What Is a Bridge Loan and How Does It Work?

A bridge loan is short-term financing that lets you tap the equity in your current home to help buy your next one before the first house sells. It "bridges" the gap between two closings, usually for a matter of months, giving you cash for a down payment and sometimes the breathing room to carry two housing payments for a short time. In exchange, you generally pay higher interest and more fees than a standard mortgage, and you take on the risk that your old home sells more slowly than expected. Bridge loans can make a strong, non-contingent offer possible in a competitive market, but they are one of the more expensive and higher-risk ways to solve the "buy before you sell" problem.

Bridge loan terms, rates, and even availability vary widely by lender and by state, and the specifics below should be confirmed with a licensed loan officer before you rely on them.

What is a bridge loan?

A bridge loan (also called gap financing, interim financing, or a swing loan) is a temporary loan secured by real estate that you own. In a home-buying context, it converts part of the equity you have built up in your current home into usable cash so you can act on a new purchase without waiting for your existing home to sell and close.

The key word is temporary. Unlike a 15- or 30-year mortgage, a bridge loan is designed to be paid off quickly, typically once your old home sells. It is a stopgap, not a long-term financing plan.

How does a bridge loan work?

Home equity is the difference between your home's market value and what you still owe on it, a concept the Consumer Financial Protection Bureau (CFPB) explains in its guidance on home equity borrowing. A bridge lender lets you borrow against a portion of that equity now, then repay the balance from your sale proceeds later.

The mechanics depend on how the loan is structured, but two patterns are common.

Structure 1: A loan on your current home

The lender places a loan (often a second lien behind your existing mortgage) against your current home and gives you cash. You use that cash for the down payment and closing costs on the new home. When your old home sells, the sale proceeds pay off both your original mortgage and the bridge loan. During the bridge period you may be carrying your old mortgage, the bridge loan, and your new mortgage at once, though some bridge loans are structured as interest-only or with deferred payments to ease that squeeze.

Structure 2: A loan that pays off your current mortgage

Some bridge loans are large enough to pay off your existing mortgage and supply extra cash for the new purchase. This replaces your old mortgage with a single short-term loan, which can simplify your monthly obligations during the transition. The trade-off is a larger loan balance and, often, higher costs.

The typical timeline

Bridge loans are short by design, commonly written for a period of several months up to about a year, with the exact term set by the lender. Many are structured with a balloon payment: little or no principal is due during the term, and the full balance comes due at the end, expected to be covered by your home sale. If your home has not sold by the deadline, you may need to refinance, extend, or repay the loan another way, so an honest read on how fast comparable homes are selling in your area matters a great deal.

What does a bridge loan cost?

There is no standardized bridge loan rate or fee schedule, so treat any figure you see as a starting point for questions, not a quote. In general, expect a bridge loan to cost more than a traditional mortgage because it is short-term, higher-risk for the lender, and often processed quickly. Costs typically include:

• Interest, usually at a higher rate than a comparable first mortgage.
• Origination or administration fees charged by the lender to set up the loan.
• Appraisal and title costs, since the lender needs to confirm the value of the property securing the loan.
• Closing costs on the bridge loan itself, on top of the closing costs for your new mortgage.
• The cost of carrying multiple payments for however long the bridge period lasts.

Because you may pay closing costs twice (once on the bridge, once on the new mortgage) and carry overlapping payments, the total expense can add up faster than the headline interest rate suggests. The CFPB recommends comparing the full cost of any loan offer, not just the rate, using the Loan Estimate and closing documents lenders are required to provide. Ask each lender for an itemized list of every fee and a worst-case scenario if your home takes longer to sell than planned.

What do lenders look for?

Qualifying standards differ by lender, but bridge financing generally hinges on a few things:

• Sufficient equity in your current home, since that equity is the collateral and the expected source of repayment.
• Your ability to carry the debt, at least temporarily. Some lenders evaluate whether you could handle both housing payments; others rely more heavily on the pending sale.
• Creditworthiness, including credit history and overall financial profile.
• A credible exit, such as a listed home, a strong local market, or in some cases a signed purchase agreement on your old home.

Not every lender offers bridge loans, and requirements can shift with market conditions. This is an area to review closely with a licensed lending professional before committing.

Bridge loan pros and cons

Alternatives to a bridge loan

A bridge loan is one tool, not the only one. Depending on your equity, timeline, and risk tolerance, consider:

• A home equity line of credit (HELOC) or home equity loan on your current home, which the CFPB describes as ways to borrow against your equity, often at lower cost than a bridge loan. Note that many lenders will not open a new HELOC on a home that is already listed for sale.
• A sale-contingent offer, where your purchase depends on your current home selling first. This costs nothing extra but is weaker in a competitive market.
• A cash offer or "buy before you sell" program. Some companies front the purchase so you can buy first and sell after. Home Stimulus offers cash-offer options that can serve a similar goal to a bridge loan without a short-term loan on your books; compare the total cost and terms against a bridge loan before deciding.
• Other savings or assets, such as a gift or a loan against a retirement or investment account, each of which carries its own tax and financial trade-offs worth reviewing with an advisor.

Is a bridge loan right for you?

A bridge loan can be a sensible tool if you have strong equity, are confident your current home will sell reasonably quickly, and want to make a clean, non-contingent offer on your next home. It is riskier if your local market is slowing, your budget cannot absorb overlapping payments, or your equity cushion is thin.

Because rates, terms, fees, and even the legality of certain structures vary by lender and by state, treat this article as a starting framework rather than personalized advice. Before you commit, get written estimates from more than one lender, ask a licensed loan officer to walk you through the repayment and worst-case scenarios, and compare the bridge option against a HELOC, a contingent offer, and a cash-offer program. The right choice depends on your equity, your timeline, and how much risk you are comfortable carrying while your current home is on the market.
