Bridge vs HELOC

Bridge financing vs HELOC: how do you buy before you sell?

When your new home closes before your old one, you need short-term money to cover the down payment until your sale funds arrive. Bridge financing is purpose-built for exactly that gap — fast, short, and tied to your firm sale. A HELOC can work too, but only if it's already in place on your current home. Here's which fits your timing.

The short answer

Use bridge financing if your purchase closes before your sale and you have a firm (sold, conditions waived) sale on your current home — the lender advances your down payment for the few days to a few months between closings, secured by the equity you're about to receive. It's fast, short-term, and the default tool for this exact situation. Use a HELOC instead only if you already have one registered on your current home with room available — you can draw the down payment from it and repay when you sell. The catch: you usually can't set up a new HELOC fast enough once you're mid-deal, and many lenders freeze or require discharge of a HELOC on a home that's listed. Plan ahead, and bridge is almost always the cleaner answer.

The problem both solve: closing dates that don't line up

In a perfect world your sale and purchase close the same day, your sale proceeds roll straight into your new down payment, and you need no extra money. In reality the dates rarely match — your new home might close a week, a month, or occasionally longer before your old one does. During that gap you owe a down payment you don't have yet, because it's tied up in a home you haven't been paid for.

That's the entire job of bridge financing: it advances that down payment for the in-between period and is repaid automatically when your sale completes. A HELOC can fill the same gap by letting you draw the cash from your current home's equity. The difference is less about what they do and more about timing and setup — which is what determines which one is actually available to you when you need it.

Why bridge financing is usually the right tool

Bridge financing is designed for this and only this, which makes it clean and fast. Your lender looks at your firm sale — a sold deal with conditions waived — and advances your down payment against the equity you're guaranteed to receive. Because the repayment source is locked in, lenders are comfortable arranging it quickly, often right alongside your new mortgage with the same lender. The cost is modest: interest for the short period (commonly prime plus a margin) and a small administration fee.

The key requirement is that firm sale. Bridge financing generally needs your current home to be sold with conditions removed — lenders bridge against a sure thing, not a hope. If your home is listed but not yet sold, bridging is harder (some lenders won't, others charge more). So the practical move when you're buying before selling is to get your sale firm first, then bridge the gap to your purchase. Our bridge financing guide walks through the mechanics.

When a HELOC is the better fit (and when it isn't)

A HELOC can be the smarter, cheaper option in one specific scenario: you already have one open on your current home, with enough room to cover the down payment. In that case you simply draw the funds, complete your purchase, and repay the HELOC when your sale closes — no new application, and the rate may be lower than a bridge.

But two things trip people up. First, you usually can't set up a new HELOC fast enough once you're already mid-purchase — HELOC approval involves full underwriting and registration, which doesn't fit a tight closing timeline. Second, many lenders freeze or call a HELOC on a home that's listed for sale or under contract, because the security is about to disappear. So a HELOC is a great gap solution only if it was set up well in advance and your lender permits drawing on it while the home is being sold. If you're already planning a move, opening a HELOC early — before you list — is a savvy way to keep options open. See smart uses of home equity.

The real lesson: plan the financing before the dates bite

Whichever tool you use, the mistake is leaving it to the last minute. Buyers often focus entirely on finding the home and negotiating the price, then discover at the eleventh hour that their closing dates leave a funding gap. By then, options narrow fast — a new HELOC is too slow, and a bridge needs your sale to be firm.

The fix is simple: talk to us before you write offers. We'll map your likely timing, line up bridge financing with your new mortgage, or — if a move is on the horizon — set up a HELOC on your current home well ahead of listing so you have flexibility either way. This is also where working through a broker pays off: we coordinate the sale, the purchase, and the gap financing as one plan rather than three scrambles. Maya can sketch your timing in minutes, any time.

Your situation

Which is right for you?

New home closes 2 weeks before your sale

Usually: Bridge financing

The classic case. Get your sale firm, then bridge the down payment for the short gap — repaid automatically when your sale closes.

You already have a HELOC with room

Usually: HELOC

Draw the down payment from your existing line and repay it from your sale. Often cheaper than a bridge — if your lender allows it while listed.

Home listed but not yet sold

Usually: Bridge (once firm) or wait

Most lenders bridge only against a firm sale. Get conditions waived first, or line up a HELOC before you list to keep flexibility.

A move is on the horizon, not imminent

Usually: Set up a HELOC now

Opening a HELOC before you list gives you a ready-made gap solution and general flexibility — set it up early while it's easy to qualify.

What's the difference between bridge financing and a HELOC?

Bridge financing is a short-term loan built specifically to cover your new down payment during the gap between your purchase closing and your sale closing — it's arranged fast against your firm sale and repaid automatically when you sell. A HELOC is a revolving line of credit on your current home you can also draw for the down payment, but only if it's already set up with room available. Bridge is the purpose-built default; a HELOC works mainly if it pre-exists.

Do I need a firm sale to get bridge financing?

Usually, yes. Most lenders bridge against a sold, firm deal (conditions waived) because that's the guaranteed source of repayment. If your home is listed but not yet sold, bridging is harder — some lenders decline it, others charge more or require a larger equity cushion. The clean path is to get your sale firm first, then bridge the gap to your purchase.

Can I use a HELOC to buy before I sell?

Yes, if you already have a HELOC on your current home with enough available room and your lender permits drawing on it while the home is listed or sold. The problem is timing: you usually can't open a new HELOC fast enough once you're mid-deal, and many lenders freeze a HELOC on a home that's being sold. So it works best when set up well before you list.

How much does bridge financing cost?

Typically interest for the short bridge period (often prime plus a margin) plus a small administration fee — usually a few hundred dollars. Because the term is so short (days to a few months) and it's secured by your firm sale, the total cost is modest relative to the convenience of buying your next home without waiting for your sale to close.

When should I arrange gap financing?

Before you write offers. The most common mistake is sorting out closing-date financing at the last minute, when a new HELOC is too slow and a bridge needs your sale to be firm. Talk to a broker early so we can map your timing and line up bridge financing with your new mortgage — or set up a HELOC on your current home ahead of listing to keep options open.
