Buying Before You Sell: How Bridge Loans Work and When They're Worth It

Meta description: A bridge loan lets you make a non-contingent offer using your current home's equity. Here's what it costs, what the risk is, and the cheaper options to rule out first.

You find the house. It's right, it's priced fairly, and it will be gone by Sunday. But your down payment is sitting in a house you haven't listed yet, so the only offer you can write comes with a home sale contingency attached.

In a competitive market, that offer loses to a clean one at the same price. Often at a lower price.

A bridge loan is one way out of that. It's also not the only way, and it isn't free, so it's worth understanding all three parts before you commit.

How it works

A bridge loan is short term financing, usually six to twelve months, secured against the equity in your current home. You use it for the down payment on the new house, then pay it off from the sale proceeds when your old home closes.

Say your current house is worth $800,000 with $350,000 left on the mortgage. A lender capping you at 80% combined loan-to-value would look at $640,000, subtract your existing balance, and leave roughly $290,000 of accessible equity. That's your bridge, minus costs, and it becomes your down payment on the new place.

Payments are typically interest-only. Some programs defer payments entirely until payoff, which helps your monthly cash flow but doesn't make the interest disappear. It accrues either way.

What it costs

Expect origination points, a rate meaningfully above a conventional first mortgage, and sometimes an exit fee at payoff. On a six month bridge you're often looking at several thousand dollars in interest plus a point or two upfront.

Whether that's worth it depends on what the alternative costs you. If a contingent offer means losing the house, or winning it at $30,000 more to compensate the seller for the risk, the bridge is cheap. If your market is slow and sellers are accepting contingencies without a premium, it isn't.

The part that deserves a straight answer

The risk is that your house doesn't sell.

If the bridge term runs out with your old home unsold, you're paying an extension fee, still carrying both mortgages, and now under real pressure to cut your price. People got hurt by exactly this when the market shifted in 2022. The bridge didn't cause the problem, but it converted a slow sale into an expensive one.

So before you take one, get honest about two things. What are comparable homes in your neighborhood actually taking to sell right now, not what your agent hopes, and could you carry both payments for three months past the bridge term if you had to? If the answer to the second question is no, the risk may be larger than it looks from inside a market where things are moving fast.

None of this means don't do it. It means price the downside before you sign.

Cheaper options to rule out first

A HELOC on your current home. Usually far cheaper than a bridge loan. The catch is timing: most lenders won't open a HELOC on a home that's listed, and the process takes several weeks. So this only works if you set it up before you go to market. If you're thinking about moving next spring, open the line now while your house is still just your house.

A cash-out refinance on the current home, same logic and same timing constraint.

A rent-back. Sell first, then lease the house back from your buyer for 30 to 60 days while you close on the next one. This solves the double-move problem, costs almost nothing, and gets skipped constantly because people forget it's available. In a market where buyers are competing, plenty of them will agree to it.

Minimal down now, recast later. Put down what you can on the new house, then after your old home sells, apply a large principal payment and ask the lender to recast the loan. Recasting recalculates your payment on the lower balance at your existing rate, usually for a few hundred dollars in fees rather than the cost of a refinance. Not every loan permits it, so ask before you close, but when it's available it's an elegant solution.

A contingent offer with a kick-out clause. In a slower market this is sometimes perfectly acceptable to sellers. Ask your agent how contingent offers are actually being received in your specific area before assuming they're dead on arrival.

When a bridge is the right call

It usually makes sense when you have substantial equity, your local market is moving quickly enough that you're confident in a sale, the house you want won't wait, and you could absorb a delay without it becoming a crisis.

It's a harder call when your equity is thin after costs, when inventory in your neighborhood is sitting, or when the numbers only work if everything goes right.

One qualification note

You'll generally need to show you can carry both mortgage payments unless your current home is already under contract with contingencies cleared. That surprises people who assumed the bridge itself solves the qualification problem. Worth knowing early, because it determines how much house you can actually buy.

We do bridge financing, and we'll also tell you when a HELOC opened three months from now, or a rent-back, gets you the same result for less money. That conversation is most useful before you list, not after you've found the house.
