What Is a Bridge Loan? Buying Before Selling

A bridge loan exists because of a timing problem that money cannot normally solve. You have equity, sometimes a great deal of it, and it is locked inside a house you still live in. The house you want is available now, the seller wants a clean offer now, and the equity will not be liquid until a stranger signs a contract on your current home at a price you cannot yet name. A bridge loan turns that future, uncertain cash into present, spendable cash, and charges you for the privilege in a way that is easy to underestimate.

This breakdown works through what the loan actually is, how lenders size and secure it, the shape its cost takes across interest and fees, what qualifying looks like while you carry two housing payments, and the four common alternatives with honest numbers against each. Every figure is illustrative and carried unchanged through the body, both charts, the companion, and the questions at the end. If you want the equity mechanics behind all of this first, our loan-to-value breakdown sets out how lenders measure the room you have, and the HELOC rundown covers the cheaper cousin that has to be arranged earlier. You can price your own version in about a minute with the companion calculator below.

What a bridge loan actually is

A bridge loan is a short-term loan secured by real property and designed to be repaid from a specific, identifiable event: the sale of a home. It is sometimes called bridge financing, swing financing, or a gap loan, and in the residential world it almost always sits alongside a purchase that is happening on a schedule the borrower does not fully control. The loan is not a mortgage in the ordinary sense, even though it is secured by a house, because a mortgage is repaid out of monthly income over decades and a bridge is repaid out of a lump sum within months.

That distinction is worth holding onto because it explains the whole product. When repayment depends on an event rather than a paycheck, the lender’s central risk is not whether you can afford the payment. It is whether the event happens on time and produces enough money. Underwriting therefore concentrates on the collateral, on how salable it is, and on what happens if the timeline slips, which is a different set of questions from the ones a first-mortgage underwriter asks.

Bridge loans also come from a different part of the lending market. Conventional first mortgages are largely standardized because they are written to be sold into a secondary market with published rules. Bridge loans generally are not, which means each lender writes its own credit policy, its own fee schedule, and its own extension terms. Two quotes for the same borrower on the same house can differ far more than two first-mortgage quotes would, and there is no published rate sheet you can check against.

The problem it solves: equity you own but cannot spend

Picture the position without the loan. You have paid down a mortgage for years, prices have moved, and the difference between what your home is worth and what you owe on it is substantial. On paper you are in an excellent position to buy. In practice you cannot write a down payment cheque against a balance sheet entry, and the only mechanism that converts that entry into money is a completed sale with a settlement statement attached.

The alternative most people try first is a contingent offer, meaning an offer to buy that is conditional on their own home selling. That works, and it costs nothing on a fee sheet, but it moves the cost somewhere less visible. A seller comparing two offers at the same price will usually prefer the one that does not depend on a third party’s mortgage approval, so the contingency is effectively paid for in negotiating power, in price, or in not getting the house at all.

The second thing people try is to sell first and rent. That is financially the cleanest route and it is genuinely a good answer for many households. It also means two moves, storage, a lease, and the risk of watching the market you intend to buy back into move while you sit in it. A bridge loan exists for people who have decided the cost of two moves and a rental exceeds the cost of a few months of expensive interest.

Where the figures in this breakdown come from

Every dollar figure here is constructed rather than quoted. RefiNook does not publish live bridge pricing, and no article honestly can, because bridge terms are quoted individually against a specific property, a specific appraisal, a specific credit file, and a specific lender’s appetite in a specific week. What follows is arithmetic on one set of illustrative inputs, chosen to be round and ordinary, and carried unchanged through the body, both charts, the calculator, and the questions at the end.

Those inputs are a departing home valued at $500,000 with a $250,000 mortgage balance on it, a lender working to an 80 percent combined loan-to-value cap, a $150,000 bridge at 10.5 percent interest-only with a 1.5 percent origination fee and about $2,500 of third-party charges, a six-month term with an extension option priced at 1 percent, a new home at $650,000 with 20 percent down, and a new first mortgage of $520,000 at 6.5 percent over thirty years. Selling costs on the old home are taken at an illustrative 6 percent.

None of those numbers are predictions. Bridge rates in the market vary by a wide margin between lenders and move with conditions; origination fees, extension pricing, and combined loan-to-value caps are set by individual credit policy rather than by rule; and selling costs depend on your agreement with your agent and on local transfer charges. Treat the structure of the arithmetic as the transferable part and replace every figure with your own quote.

The illustrative move this breakdown runs on

Hold one move in mind for the rest of this article. You own a home worth roughly $500,000 with $250,000 left on the mortgage, giving you $250,000 of equity. Your current housing payment runs an illustrative $2,100 a month, of which about $1,650 is principal and interest and about $450 covers property taxes and homeowners insurance. If the composition of a housing payment is unfamiliar, our PITI breakdown walks through the four parts.

You want to buy at $650,000 and put 20 percent down, which is $130,000, and you expect closing costs on the purchase of roughly $9,750. That means you need about $139,750 in cash at the new closing, and you do not have it sitting in an account, because it is sitting in a house. The new mortgage would be $520,000 at 6.5 percent over thirty years, which carries a principal and interest payment of about $3,287, and with an illustrative $700 a month for taxes and insurance the new housing payment is roughly $3,987.

Note what is not in dispute. You can afford the new house once the old one sells. The entire problem is a window of a few months in which you own two houses, owe on both, and have not yet received the proceeds that make the arithmetic work. The bridge is a tool for surviving that window, and its cost should be judged against what the window is worth to you rather than against a mortgage rate.

How lenders size a bridge loan

Bridge sizing generally starts with the collateral, not with you. The lender takes a value for the property being pledged, applies a maximum combined loan-to-value from its own credit policy, subtracts any existing liens, and what remains is the ceiling. On the illustrative figures, an 80 percent cap on a $500,000 home allows $400,000 of total secured debt against it. The existing mortgage takes $250,000 of that, so the bridge ceiling is $150,000.

Three things move that ceiling. The cap itself varies, and a lender working to 75 percent instead of 80 percent would allow only $375,000 total, cutting the bridge to $125,000 on the same house. The value is set by an appraisal or an accepted valuation rather than by your estimate, and a valuation that lands below your expectation shrinks the loan directly. And the existing balance keeps falling as you pay it, which is the one input moving in your favour.

Some lenders size against both homes at once, called cross-collateralization, which can raise the ceiling because there is more property backing the loan. That flexibility comes with a real cost: two properties are now encumbered, and releasing the new home from the lien after the old one sells is an administrative step with its own timing and paperwork. Ask how the release happens and how long it takes before you agree to pledge the house you intend to keep.

What secures the loan: one house, the other, or both

The most common residential arrangement puts the bridge lien on the departing residence, behind the existing first mortgage. That keeps the new purchase clean, which matters because the new first-mortgage lender has its own rules about what else can be recorded against the property it is lending on. It also means the bridge is a second lien, repaid only after the first mortgage is satisfied out of sale proceeds, which is one of the reasons it is priced the way it is.

A second arrangement puts the lien on the new home instead, functioning as a second mortgage behind the new purchase money loan. This shows up when the departing home is hard to value, hard to sell, or already encumbered close to the cap. It is less common precisely because it burdens the asset you are keeping, and because many purchase-money lenders restrict simultaneous secondary financing they have not approved.

The third arrangement is cross-collateralization, where the lender records against both. From the lender’s side this is the safest structure and it often produces the best pricing. From the borrower’s side it concentrates risk: a problem with the sale now touches the home you just bought, not only the one you are leaving. If a lender offers a materially better rate for cross-collateralizing, the discount is real, and so is the reason they are offering it.

Whatever the structure, the practical mechanics run through the title company. The bridge lender records a lien, the payoff is ordered when the departing home goes to closing, and the settlement agent wires the payoff before any proceeds reach you. That is why the loan feels invisible on sale day and why an error in the payoff demand is one of the few things that can delay a closing at the last minute.

How the payments are structured

Three payment shapes dominate, and the difference between them is entirely about cash flow during the overlap. The most common is interest-only monthly. On the illustrative $150,000 at 10.5 percent, that is $150,000 multiplied by 0.105 and divided by twelve, or $1,312.50 a month, which most term sheets would round to about $1,313. Principal does not move; the entire balance is repaid at the sale.

The second shape is deferred or accrued interest, sometimes marketed as a no-payment bridge. Nothing leaves your account monthly, and the interest is added to the balance and settled in the lump payoff. This is genuinely useful when the overlap would otherwise break your monthly budget, and it is more expensive than it looks, because the balance you owe grows and the payoff at closing is larger than the amount you borrowed. Ask whether the accrual is simple or compounding and how often it is applied.

The third shape is a hybrid where a portion of the interest is paid monthly and the rest accrues, or where the lender withholds an interest reserve at closing. A reserve means part of your loan proceeds are held back to cover several months of payments, which quietly reduces the cash you actually receive. On the illustrative loan a three-month reserve would hold back roughly $3,938, so the money you can spend at the new closing falls by that amount even though your balance does not.

Typical term lengths and what maturity means

Residential bridge terms are commonly written for six to twelve months, sometimes shorter, occasionally longer for unusual properties. The term is not an estimate of how long you will need the money. It is a hard date on which the entire principal becomes due, which is what makes a bridge a balloon loan rather than an amortizing one. There is no schedule that gradually retires the debt, and no month in which it becomes smaller on its own.

Extension options are common and they are options, not rights. A term sheet may allow one or more extensions of a few months each, typically priced as a percentage of the loan amount, and typically at the lender’s discretion. In this breakdown an extension is taken at an illustrative 1 percent, which on $150,000 is $1,500 for the additional period. Read whether the extension is automatic on payment of the fee or subject to re-approval, because those are very different protections.

Prepayment deserves the same attention from the other direction. Many bridge loans have no prepayment penalty, which is what you want if the house sells quickly. Some carry a minimum interest provision, meaning you owe a set number of months of interest even if you repay in week three. A three-month minimum on the illustrative loan means you cannot pay less than $3,938 of interest regardless of how fast the sale closes, and that clause is easy to miss in a term sheet.

The cost shape: interest plus fees

Bridge cost has two parts that behave in opposite ways, and separating them is the single most useful thing you can do with a quote. Interest scales with time: every extra month adds $1,312.50 on the illustrative loan. Fees do not scale with time at all: they are charged once, at closing, and they are the same whether the house sells in three weeks or nine months.

On the illustrative loan the upfront side is an origination fee of 1.5 percent, which is $2,250, plus roughly $2,500 of third-party charges covering the appraisal or valuation, title work, escrow or settlement fees, and recording. That is $4,750 spent before a single day of interest accrues. It also means the $150,000 loan puts only about $145,250 on the table if the fees are netted out of proceeds rather than paid separately.

Add six months of interest at $7,875 and the all-in cost of the illustrative bridge is $12,625. Of that, $4,750 is fees, which is roughly 38 percent of the total. That ratio is the reason a bridge cannot be judged by its rate alone. A lender quoting a lower rate with a higher origination fee can easily be more expensive over a short hold, and the only way to know is to compute the total both ways for the timeline you actually expect.

Why the shortest bridge is the most expensive per year

Because fees are fixed and interest is not, the effective annual cost of a bridge falls as you hold it longer, which is the reverse of the intuition most borrowers bring. Selling quickly is unambiguously good for your bank balance and simultaneously produces a terrible-looking annualized rate, because you paid $4,750 of fixed cost to use money for a very short time.

Read the arithmetic behind two of those bars. Selling at month six costs $12,625, which on $150,000 borrowed for half a year works out to roughly 16.8 percent a year once fees are counted. Selling at month two costs $7,375, which sounds much better and annualizes to something close to 29.5 percent, because the same $4,750 of fees was spread over one sixth of a year instead of half of one.

The practical lesson is not to hold the loan longer. It is to stop comparing a bridge’s headline rate to a mortgage rate, because they are not the same kind of number. Compare total dollars for your realistic timeline, then ask what the total would be if the timeline slipped by three months, and decide whether both answers are survivable.

Why the rate is higher than a first mortgage

Six separate factors push bridge pricing above first-mortgage pricing, and none of them are arbitrary. The first is lien position. A bridge recorded behind an existing mortgage is paid second out of sale proceeds, so it absorbs loss first if the sale disappoints. Subordinate debt is priced higher everywhere in finance, and our piggyback breakdown shows the same spread appearing in a very different structure.

The second is term. A lender spends real money to originate any loan: underwriting, valuation, title, documentation, servicing setup. Spread across 360 payments that cost is trivial per month. Spread across six, it is not, so short-term lenders recover it through fees and a wider rate.

The third is the repayment source. A first mortgage is repaid by income the underwriter has documented. A bridge is repaid by a sale that has not happened, at a price nobody knows, on a date nobody controls. The fourth is that bridge loans generally are not eligible for sale into the conventional secondary market, so they are held on a balance sheet by a portfolio or private lender whose cost of funds is higher than the agency market’s.

The fifth is the borrower’s own position: for the length of the loan you are carrying two housing payments plus bridge interest, which is objectively a stressed profile. The sixth is the absence of an insurance market. High loan-to-value first mortgages can be de-risked with mortgage insurance, and there is no equivalent product standing behind a residential bridge. The lender carries that risk directly and charges for it.

The fees to ask about by name

Term sheets vary enough that the only reliable approach is to ask about each charge specifically rather than to ask for a total. Origination is the headline, usually quoted as a percentage of the loan and sometimes called points. On the illustrative loan, 1.5 percent is $2,250; a lender quoting 2 percent on the same amount would take $3,000, and that $750 difference outweighs a quarter point of rate over a short hold.

Then the third-party costs: appraisal or a lender-accepted valuation on the departing home, title search and lender’s title insurance, escrow or settlement fees, recording, and sometimes a document preparation charge. These land around $2,500 in this breakdown and vary considerably by state and by whether an existing title policy can be reissued at a discount.

Then the ones that only appear later. Extension fees, which we have priced at an illustrative 1 percent. Minimum interest or prepayment provisions, which set a floor on what you owe regardless of speed. Exit or release fees charged when the lien is discharged. Draw fees if the money comes in stages. Interest reserve withholding, which is not a fee at all but reduces the cash you receive. And on cross-collateralized loans, a fee to release the second property.

The useful question to a loan officer is blunt: assuming I borrow $150,000 and repay in full at month six, what is every dollar that leaves my hands, and what changes if it becomes month nine? A quote that cannot answer that in writing is not a quote you can compare against anything.

Qualifying while carrying two housing payments

Bridge underwriting looks at collateral first, but it does not ignore you, and the new first mortgage on the house you are buying will scrutinize the whole picture closely. The central question is how many housing obligations count against your debt-to-income ratio at the same time. In the strictest treatment, all three count: the departing home’s $2,100 payment, the bridge interest of $1,313, and the new home’s $3,987, which totals $7,400 a month.

Add an illustrative $600 of other monthly debt obligations and you are at $8,000. Against a debt-to-income limit of 45 percent, that implies gross income around $17,778 a month, or roughly $213,000 a year, before any lender-specific overlay. That arithmetic is why bridge borrowers skew toward high equity and high documented income, and why the product is far less broadly available than its marketing suggests.

There is an important exception. Many lenders will exclude the departing home’s payment from the ratio when there is a signed sale contract with the buyer’s own contingencies removed, because at that point the exit is close to certain. That single condition can move a borderline file into approval, which is why some households list first, get under contract, and only then bridge the gap to a purchase closing.

Beyond the ratio, expect the usual reserve and documentation requirements to tighten. Lenders commonly want several months of both housing payments held in verifiable reserves, a strong credit profile, and clean documentation of where the down payment came from. Our credit score breakdown covers how score bands tend to move pricing and approvals on the mortgage side, and the same directional logic applies here with less standardization.

What the overlap month actually costs you

It helps to write out one full month of the overlap, because the number is larger than most people picture. The old house costs $2,100 in principal, interest, taxes, and insurance, and it keeps costing that until the day it closes. The bridge costs $1,313 in interest. The new house costs $3,987. That is $7,400 a month, and it does not include utilities on two properties, lawn care and snow clearance on an empty house, or the vacant-property endorsement your insurer may require on a home nobody is living in.

Insurance is worth its own sentence, because it surprises people. Standard homeowners policies often restrict or exclude coverage on a dwelling that has been vacant beyond a set number of days, and continuing full coverage on an empty house typically means an endorsement or a specialty policy at additional cost. Confirm the terms with your own insurer before the house is empty rather than after, since a lapse there is a much bigger problem than the premium.

Then add the ordinary friction of selling: staging, minor repairs the inspection turns up, a price reduction if the first month is quiet. None of these appear on the bridge lender’s fee sheet and all of them arrive during the same window. The honest budget for the overlap is the $7,400 plus a contingency you would rather not need.

How the loan unwinds at the closing table

The exit is mechanical, which is reassuring, and it is worth understanding so nothing surprises you on the day. When your departing home goes to closing, the settlement agent orders payoff demands from every recorded lienholder. The first mortgage servicer sends one, the bridge lender sends another including per-diem interest through the expected funding date, and both are paid from the sale proceeds before anything is disbursed to you.

On the illustrative sale, $500,000 comes in. Selling costs at 6 percent take $30,000. The existing mortgage takes its $250,000 payoff. The bridge takes its $150,000 principal, since interest was being paid monthly in this version. What remains is $70,000 of cash to you, which the stacked chart above shows as the 14 percent slice. If the bridge had been the accrued-interest kind, its payoff line would be larger and that final slice correspondingly smaller.

Two details matter on the day. Per-diem interest means the payoff figure is only valid through a stated date, so a closing that slips by a week costs a few hundred dollars more and requires an updated demand. And the lien release has to be recorded afterward; if the bridge was cross-collateralized, confirm in writing that the release covers the new home too, because a stale lien on the house you are keeping will surface at the worst possible moment years later.

The break-even sale price nobody quotes you

Here is the calculation to run before you sign anything, and it is not on any term sheet. The sale has to produce enough to cover both payoffs after selling costs. Add the $250,000 mortgage payoff to the $150,000 bridge principal for $400,000 of debt. Divide by one minus your expected selling cost rate, so $400,000 divided by 0.94, and the answer is about $425,532.

That is the price at which you walk away from the closing table with exactly nothing and owe exactly nothing. Below it, you bring cash to close the sale of your own house. Against the $500,000 you believe the home is worth, the cushion is $74,468, or roughly 15 percent of value. That percentage is the honest measure of how much of a bet the bridge represents.

Run it once more with a thinner starting position to see the sensitivity. If the existing mortgage were $300,000 rather than $250,000, an 80 percent cap allows only $100,000 of bridge, total debt becomes $400,000 again, and the break-even is identical at about $425,532 while the cash you receive at the new closing falls sharply. Cap-driven sizing has the quiet property of holding your break-even roughly constant while shrinking what the loan does for you.

The number to be uncomfortable with is a cushion under about 5 percent, because ordinary price negotiation, a repair credit after inspection, and a slow month can consume that easily. At that point the bridge is not smoothing a timing problem. It is a leveraged position on your own listing price, and it should be evaluated as one.

The real risk: the old house does not sell

Everything above is arithmetic. This section is the actual risk, and it is the reason bridge loans deserve caution rather than merely comparison shopping. The entire structure assumes a sale within the term. If the sale does not happen, nothing about the loan adapts. The interest keeps accruing, the maturity date keeps approaching, and the collateral is a house you are still paying for.

The failure mode compounds. A house that has not sold in four months is usually a house that will need a price reduction, which lowers the proceeds that were supposed to clear the payoffs. Meanwhile the overlap has been costing $7,400 a month, so reserves are thinner than when you started, and the extension fee arrives at the same time. Each of those pressures makes the others worse.

There is also a market-wide version of the same risk. Bridge loans are sized off a valuation taken at one moment. If conditions soften across your area between the appraisal and the sale, the cushion you computed shrinks without anything happening to your house in particular. That is not a reason never to bridge, but it is a reason to compute the break-even against a conservative price rather than an optimistic one.

What happens if you reach maturity unsold

Take the failure seriously and plan for it in advance, because the options on the day are limited and none of them are pleasant. The first is an extension. Most lenders would rather extend a performing loan than pursue collateral, so an extension is often available for a fee, in this breakdown an illustrative $1,500 for the additional period. It buys months, not certainty, and the fee is real money on top of continuing interest.

The second is a price reduction sharp enough to clear the market. This is the option that actually works most of the time, and it costs whatever the reduction costs. Running the break-even calculation early tells you exactly how far you can cut before you are bringing cash to closing, which is a far better position than discovering that limit under pressure.

The third is refinancing the bridge into something longer. A home equity loan or line on the departing home might do it if the property still qualifies, though a listed or recently listed property complicates that considerably. Our HELOC and home equity loan comparison sets out how those two behave. Any refinance also means a second set of closing costs on the same equity.

The fourth is default, and it is not abstract. The loan is secured by real property, so a lender’s ultimate remedy is foreclosure on a house you still own. That path also damages credit in ways that affect the new mortgage you are carrying. The honest test before signing is simple: describe out loud what you would do in month nine if the house had not sold, and see whether the answer is a plan or a hope.

Alternative one: a HELOC opened before you list

The closest substitute is a home equity line of credit on the departing home, drawn to fund the down payment and repaid from the sale. On an illustrative $150,000 draw at 8.5 percent, interest-only runs $1,062.50 a month, so six months costs about $6,375. Line origination costs are commonly far lower than bridge fees, and at an illustrative $500 the all-in cost lands near $6,875 against $12,625 for the bridge.

That is a saving of roughly $5,750 on the same timeline, which makes the line the better product on cost alone. The catch is availability. Many lenders will not open a line on a property that is listed for sale, and some reserve the right to suspend or reduce an existing line if the property is listed or if the collateral position changes. The practical consequence is that the line has to be in place before the sign goes in the yard, ideally months before.

There is a second consideration on the purchase side. A drawn line is a debt, and the new mortgage lender counts it in your ratios exactly as it would count bridge interest, so the qualification arithmetic barely changes. What changes is the cost and, importantly, the maturity: a line has a draw period measured in years rather than a balloon measured in months, which removes the single sharpest risk in the bridge structure.

If you are reading this before you list, opening a line is very likely the cheaper path, and our HELOC rundown covers how draw periods and variable pricing work. If you are already listed, this option may simply be closed to you, which is precisely the gap the bridge product fills.

Alternative two: a contingent offer

A sale contingency costs nothing in fees and shifts the entire timing risk back to the seller of the home you want. Your purchase becomes conditional on your own home selling within a defined period, and if it does not, you generally recover your deposit and walk. On pure financial exposure it is the safest route available.

The cost shows up in competition. A seller weighing two similar offers will usually prefer the one that does not depend on someone else’s listing, someone else’s buyer, and someone else’s mortgage approval. In a market with multiple offers a contingent bid may not be considered at all, and where it is considered it often needs to be higher to compensate. If a contingency effectively costs you 2 percent of a $650,000 purchase, that is $13,000, which is more than the illustrative bridge.

Sellers also protect themselves with kick-out clauses, which allow them to keep marketing the home and give you a short window to remove your contingency if another offer arrives. That converts your safe position into a sudden deadline, and the tool people reach for to remove the contingency in a hurry is, predictably, a bridge loan arranged under time pressure at whatever terms are available.

The honest framing is that a contingent offer is not free, it is differently priced. It costs negotiating power rather than dollars, and whether that is a better trade depends entirely on how competitive your market is and how much you want the specific house.

Alternative three: sale-leaseback and buy-before-you-sell programs

A cluster of companies now offer variations on the same idea: a third party provides the cash so you can make a non-contingent offer, and recovers it when your old home sells. Some buy your departing home outright at an agreed price and then resell it, sharing any upside above that figure. Others buy the new home in cash on your behalf and sell it to you once your mortgage is ready. Some structure it as a sale-leaseback in which you sell your home, receive the equity, and rent it back for a defined period while you move.

The cost is usually a program fee expressed as a percentage of a purchase or sale price rather than of the amount borrowed, which makes it harder to compare against a bridge. At an illustrative 2.4 percent of the $650,000 purchase, the fee is $15,600, against $12,625 all in for the bridge on a six-month timeline. Rent during a leaseback period is typically additional, and the agreed price for a guaranteed purchase of your old home may sit below what an open-market sale would fetch.

What these programs genuinely deliver is certainty and speed, and for some households that is worth paying for. What they do not deliver is a free lunch, and the comparison is only meaningful if you price the fee against the amount of cash actually made available and the number of months it is needed. Read carefully for who captures any upside if the old home sells above the guaranteed figure.

Alternative four: borrowing from a 401k or an investment portfolio

Two non-real-estate sources come up regularly. A loan from an employer retirement plan is available only if the plan permits it, and plan rules commonly limit the amount to a share of the vested balance subject to a statutory dollar cap that changes over time. Do not plan around a specific ceiling from memory; the plan administrator can tell you the current figure and the repayment terms that apply to you. Interest is generally paid back into your own account rather than to a lender, which is the appealing part.

The risks are specific and worth stating. Repayment usually comes from payroll on a fixed schedule, which adds to the monthly load during an already expensive overlap. Leaving the employer, voluntarily or otherwise, commonly accelerates repayment, and an unpaid balance can be treated as a taxable distribution with potential penalties depending on circumstances. Those are tax questions, so put them to a qualified tax adviser rather than to a mortgage lender.

The second source is a securities-based line of credit against a taxable investment portfolio. Pricing is often lower than bridge pricing because the collateral is liquid, so an illustrative 7.5 percent on $150,000 would be about $938 a month, or $5,625 over six months, frequently with minimal origination cost. The risk is a maintenance call: if the portfolio’s value falls below a threshold, the lender can demand you post more collateral or repay immediately, and forced selling in a down market is exactly the scenario you were trying to avoid.

Neither of these is inherently better or worse than a bridge. They move the risk from your listing to your employment or your portfolio, and the right answer depends on which of those you consider most stable.

How the five routes compare

Line the options up on the same illustrative timeline and the pattern is clear. The bridge costs about $12,625 for six months, is available late, and carries a hard maturity. The line of credit costs about $6,875 on the same money, has no balloon inside the draw period, and must be arranged before listing. The contingent offer costs nothing in fees and may cost several times the bridge in purchase price or in simply losing the house.

The buy-before-you-sell program costs an illustrative $15,600 in fees plus any rent and any foregone upside, and delivers the strongest offer position and the most certainty. The portfolio line costs about $5,625 with the lowest fees and the sharpest tail risk. A retirement plan loan costs interest paid to yourself plus a tight repayment schedule and a job-change trap.

Two questions sort this quickly. First, has the house been listed yet? If not, price a line of credit before anything else, because it is usually the cheapest instrument and the window to arrange it is open. Second, how confident are you in the sale, honestly, at a price with real cushion above the break-even? High confidence favours the cheapest instrument you can access. Low confidence favours the routes that do not put a house you own behind a balloon payment.

A third question is worth asking of yourself rather than of a lender: what is speed actually worth here? If the answer is that the specific house is worth several thousand dollars of expensive interest, a bridge is a rational purchase of certainty. If the answer is that you would be nearly as happy with a different house in four months, the expensive instrument is solving a problem you do not have.

Who a bridge loan is actually right for

The profile that fits is fairly narrow, and being honest about it saves people money. It is a household with substantial equity, comfortably above the break-even cushion; documented income that survives a strict ratio treatment or a signed sale contract that lets the departing payment be excluded; reserves deep enough to carry the overlap for longer than expected; and a departing home that is genuinely salable in its market rather than unusual, over-improved, or priced on hope.

It also fits situations where speed has a specific dollar value. Relocation with a start date, a house that will not stay available, a purchase that only makes sense at a particular price, an estate or family situation with its own timetable. In each case the bridge is buying something identifiable, and the identifiable thing can be weighed against $12,625.

The profile that does not fit is equally recognizable. Thin equity, a cushion under a few percent, reserves that cover the overlap only if nothing goes wrong, or a departing home you privately suspect is priced above what the market will pay. In those cases the bridge does not solve the timing problem, it adds a deadline to it.

There is also a middle case worth naming: the household that could bridge but does not need to. If you can carry both payments comfortably and the equity is large, a home equity line arranged early does the same job for roughly half the cost with none of the balloon risk. Reaching for a bridge when a line was available is one of the more common and most avoidable expensive decisions in this whole area.

Questions to ask before you sign the term sheet

Ask what the maximum combined loan-to-value is and what value it will be applied to, because that pair sets the loan size before anything else is discussed. Ask which property or properties will be encumbered, and if both, how and when the release on the new home happens. Ask whether the rate is fixed for the term or can move.

Ask for the complete list of charges in dollars, not percentages, for a payoff at your expected month and again three months later. Ask specifically about minimum interest and prepayment provisions, because a fast sale is the outcome you are hoping for and it should not be penalized. Ask whether an interest reserve will be withheld, and if so how much, since that reduces the cash available at your purchase closing.

Ask what the extension looks like: how many, how long, at what fee, automatic on payment or subject to re-approval. Ask what happens at maturity if the property is unsold and no extension is granted, and get the answer in writing rather than as reassurance. Ask how the payoff demand process works and what per-diem applies.

Finally, ask the new mortgage lender, separately, how the bridge will be treated in their underwriting: whether it counts in your ratios, how the down payment funds must be sourced and documented, and whether a signed sale contract on the departing home would change the treatment. That answer can change which product you should be using at all, and it is better obtained before you have paid an origination fee. Run your own version of the arithmetic with the payment calculator and the companion above before either conversation.

The bottom line

A bridge loan is short-term secured borrowing that converts equity you cannot spend into cash you can, repaid by a sale rather than by income, and priced accordingly. Sizing starts from a combined loan-to-value cap on the departing home, so an illustrative 80 percent cap on a $500,000 property carrying $250,000 of mortgage supports about $150,000. Six months of that at 10.5 percent interest-only costs about $7,875, upfront fees add about $4,750, and the all-in figure lands near $12,625 with roughly 38 percent of it in charges that do not shrink if you sell early.

The rate sits above a first mortgage for structural reasons, subordinate lien position, a term too short to spread origination costs across, a repayment source that has not happened yet, no secondary market, a stressed borrower profile, and no insurance product standing behind it. Qualifying means surviving an underwriter who may count three housing obligations at once, which on the illustrative move totals $7,400 a month before utilities or vacancy coverage.

Price the alternatives honestly rather than reflexively. A line of credit arranged before you list costs roughly half as much and has no balloon; a contingent offer costs no fees and may cost far more in price; a buy-before-you-sell program costs the most in fees and delivers the most certainty; a portfolio line is cheap with a sharp tail. And compute your break-even sale price, about $425,532 on these figures, so you know how much room the market has to disappoint before you are bringing cash to your own closing. Then take the term sheet, your real numbers, and your honest timeline to a licensed mortgage professional before you commit.

Before you act on anything above: this breakdown is educational general information from RefiNook, not mortgage, tax, legal, or financial advice, and it cannot see your appraisal, your credit file, your local market, or the term sheet in front of you. Every rate, fee percentage, cap, term length, month, and dollar amount here was constructed to make the arithmetic visible and describes no real lender, property, or borrower. Bridge lending is not standardized the way conventional mortgages are, so combined loan-to-value caps, origination and extension pricing, minimum interest clauses, collateral structures, and qualification overlays are written individually by each lender and change with market conditions. Retirement plan loan limits and their tax treatment are set by rule and revised over time, so confirm those with your plan administrator and a qualified tax adviser rather than with anything written here. Get every charge in writing, price at least two alternatives on your own expected timeline, and let a licensed mortgage professional review the whole structure before you pledge a house against it.
