What Is a Bridge Loan for Buying a Home?
Selling one home and buying another rarely happens on the exact same day. A bridge loan exists for the gap in between, when a buyer’s equity is tied up in a house that hasn’t sold yet but a new purchase is ready to move forward.
The short answer
A bridge loan is a short-term loan that lets a homeowner borrow against the equity in their current home to cover a down payment or purchase costs on a new home, before the current home actually sells. It’s meant to be temporary, typically repaid once the existing home closes, and it generally carries higher interest rates and fees than a standard mortgage in exchange for that short-term flexibility.
How the mechanics typically work
A lender evaluates the equity in the borrower’s current home and extends a short-term loan against it, often structured so the borrower makes interest-only payments, or in some cases no payments at all, until the current home sells and the loan is paid off in full. Because it’s secured by the existing home’s equity, the borrower generally needs meaningful equity built up already for this to work, which is one reason bridge loans tend to come up for people who have owned their current home for a while rather than recent buyers.
Where it fits in the home-buying timeline
Bridge loans typically enter the picture after a buyer has found a new home they want to purchase but hasn’t closed on the sale of their current one. It sits alongside other early transaction steps like earnest money and the loan estimate process for the new mortgage, but it’s a separate, parallel piece of financing rather than part of the new home’s primary loan. Once the old home sells, the bridge loan is generally paid off from the sale proceeds, closing out that short-term obligation.
Who this tends to apply to
This structure applies most directly to buyers in a specific bind: enough equity in a current home to make the math work, a competitive local market where a contingent offer (one dependent on selling first) is less attractive to sellers, and a need to move quickly on a new purchase. It’s less relevant for first-time buyers, who don’t have an existing home’s equity to borrow against, and it tends to be more common in markets where sellers strongly prefer offers that aren’t contingent on another sale.
How it compares to the alternative
The main alternative to a bridge loan is a contingent offer — making an offer on a new home conditional on successfully selling the current one first. A contingent offer avoids taking on short-term debt but can be a weaker offer in a competitive market, since sellers may prefer a buyer without that condition attached. A bridge loan effectively removes the contingency by providing cash upfront, at the cost of extra interest and fees, and the risk that the current home takes longer to sell than expected, which extends how long the borrower carries both the bridge loan and the new mortgage.
A common mistake
A common mistake is underestimating how long the current home might take to sell, which extends the period of paying for a bridge loan on top of a new mortgage payment, sometimes alongside the old mortgage too if it hasn’t been paid off yet. Because carrying multiple loan payments at once can strain a budget and affect how a lender views a borrower’s debt-to-income ratio on the new mortgage, it’s worth thinking through a realistic, even conservative, timeline for the sale rather than assuming the best-case scenario.
What to weigh
A bridge loan solves a specific, timing-related problem — needing funds from a home that hasn’t sold yet — at the cost of higher short-term borrowing expenses and the risk of an uncertain sale timeline. Because terms, availability, and typical costs vary by lender and local market conditions, and because carrying two properties’ worth of financing is a meaningful commitment, it’s worth weighing the realistic range of outcomes rather than assuming the fastest-case scenario will happen.
