Bridge Financing: Buying Before Your Sale Closes

Your new home closes two weeks before your old one sells. Bridge financing is the short-term loan that covers your down payment in the meantime.

The short answer

Bridge financing is a short-term loan that lets you use the equity from your current home — which hasn't sold yet — to fund the down payment on your new home when the closing dates don't line up. It's typically arranged through your existing mortgage lender and repaid the moment your old home's sale closes.

Why the timing gap happens

It's common for a buyer's new home to close before their existing home's sale closes, whether by a few days or a few weeks — closing dates are negotiated independently for each transaction and rarely line up perfectly by coincidence. That gap creates a real problem: you may need your equity from the home you haven't sold yet to fund the down payment on the home you're about to close on.

How bridge financing actually works

A bridge loan is a short-term loan, usually arranged through the same lender handling your new mortgage, that advances you funds against the equity in your current, unsold home — funds you'll use toward your new purchase's down payment. It's automatically repaid the moment your existing home's sale actually closes and those proceeds land, which is why lenders generally require a firm, unconditional sale agreement on your current home before approving one; a merely listed home isn't enough.

What it costs

Typical bridge loan interest ratePrime + 2-3%
Approximate interest cost, 12 days~$600–$800
Administration fee (lender-dependent)$200–$500

Because it's short-term, the total dollar cost is often manageable even though the annualized rate looks high — but it's a real cost that needs to be part of your closing budget, not an afterthought.

When you might not need one

If you can arrange your closing dates to align — either by negotiating a longer closing on your purchase or a rent-back arrangement after your sale closes — you can sometimes avoid needing bridge financing altogether. It's worth raising this possibility with your realtor early in the process, since it's much easier to negotiate matching dates upfront than to arrange bridge financing under time pressure later.
