Bridge Loan vs HELOC: Buy Before You Sell
Use a HELOC if you can open it before you list your current home and you want the cheapest, most flexible way to fund the next down payment; use a bridge loan if you have already listed, need a large lump sum fast, or want a short-term loan you repay in full when the old home sells. The deciding factor is timing: HELOCs must be set up while you still qualify, bridge loans are built for the gap after you have committed to buying.
The move-up buyer's problem, in one sentence
Your down payment for the next house is locked inside the walls of the house you still live in. You cannot list it, sell it, and cash out before you make an offer, because the home you want will be gone by then. A bridge loan and a home equity line of credit (HELOC) both solve this by letting you borrow against your current equity so you can buy first and sell second. They work in opposite ways, and the right one depends almost entirely on when you start planning.
In California, where a departing home often carries $400,000 to $900,000 of equity and the next purchase closes in 21 to 30 days, the stakes are real: choose wrong and you either pay far more than necessary or find yourself unable to qualify at all. Save Financial (NMLS #377740), a mortgage broker serving Newport Beach and Marina del Rey, structures both routes, so this is a comparison of tools, not a sales pitch for one.
How a HELOC works for buy-before-you-sell
A HELOC is a revolving line of credit secured by the equity in your current home. Once approved, you draw only what you need, when you need it, and pay interest only on the drawn balance. For a move-up buyer, the play is simple: open the line, draw enough to cover the down payment and closing costs on the new home, buy the new home, then pay the line back to zero when the old home sells.
The catch that trips up most buyers is sequencing. Lenders will not approve a new HELOC on a home that is already listed for sale, and many freeze or reduce lines the moment a property hits the market. You must open the HELOC while the home is not listed and while you still qualify on your current income and debt load. A HELOC opened three weeks before listing is a powerful tool; a HELOC you try to open after the sign goes in the yard usually does not exist.
Typical California HELOC terms in 2026: credit limits up to 80% to 90% combined loan-to-value, variable rates tied to the Prime Rate (Prime plus a margin), a 10-year draw period, and closing costs that are often $0 to a few hundred dollars. Interest is charged only on what you draw, so a line that sits unused costs almost nothing.
How a bridge loan works for buy-before-you-sell
A bridge loan is short-term financing, usually 6 to 12 months, that gives you a lump sum secured by your departing home, your new home, or both. You use the proceeds for the down payment (and sometimes to pay off the old mortgage entirely), close on the new home, then repay the bridge loan in full from the sale proceeds of the old home. Many bridge loans require no monthly payments during the term, or interest-only payments, with the full balance due when the old home sells.
The advantage is speed and timing freedom. A bridge loan can be arranged after you have already listed or even after your old home is in escrow, which is exactly when a HELOC is off the table. It hands you a large, certain sum rather than a line you have to draw against, and it can make your offer on the new home look like a non-contingent, cash-strong bid in a competitive market.
The cost is higher. California bridge loans commonly carry rates several points above conforming mortgage rates, plus origination fees of 1% to 3% of the loan amount and administrative costs. You are paying a premium for a short-term, higher-risk loan that a lender expects to be repaid within a year.
Head-to-head: bridge loan vs HELOC
| Factor | Bridge loan | HELOC |
|---|---|---|
| Structure | Short-term lump sum | Revolving line of credit |
| Secured by | Departing home, new home, or both | Departing (current) home |
| Must be set up | Can arrange after listing or in escrow | Before you list the home |
| Repaid when | Old home sells (6 to 12 months) | Old home sells, then reusable during draw period |
| Typical rate | Higher, several points above mortgage rates | Variable, Prime plus a margin |
| Upfront cost | 1% to 3% origination plus fees | Often $0 to a few hundred dollars |
| Monthly payment | Interest-only or none until payoff | Interest-only on drawn balance |
| Best for | Already listed, need speed and a lump sum | Planned ahead, want low cost and flexibility |
The single most important row is the third one. A HELOC is cheaper on almost every measure, but it is only available to buyers who plan far enough ahead to open it before listing. Miss that window and the bridge loan is often the only remaining option.
Timing and qualification differences
Qualification. A HELOC underwrites like a conventional loan: the lender checks your credit, income, and debt-to-income ratio, and must be comfortable that you can carry your current mortgage plus the new HELOC payment. If you cannot qualify while both debts are on your books, the line will not be approved. A bridge loan leans more heavily on the equity and the expected sale, so lenders can approve borrowers who look overextended on paper, precisely because repayment comes from a sale rather than monthly income.
Speed. A HELOC typically takes 2 to 4 weeks to open, which is why it must be started before you list. A bridge loan can often close in 1 to 2 weeks, matching the compressed timeline of a live purchase.
The listing line in the sand. The moment your current home is publicly for sale, most HELOC lenders will decline a new line or freeze an existing one. Bridge lenders expect a sale to be underway and price for it. This is the practical fork in the road: plan early and the HELOC is yours; act late and the bridge loan carries you across.
Cost and risk: what you actually pay and where it can go wrong
Cost. On a $150,000 need for down payment and closing costs, a HELOC held for four months might cost a few thousand dollars in interest and almost nothing upfront. A bridge loan for the same amount over the same period can cost several thousand more once origination fees and the higher rate are counted. Over a short holding period the dollar gap is real but not enormous; over a longer-than-expected timeline it widens fast.
Risk. Both products assume your old home sells on schedule. If the market slows and your home sits, a HELOC keeps accruing interest on a home you are still carrying, while a bridge loan can come due before the sale closes, forcing an extension (with more fees) or a price cut to sell quickly. You are, in both cases, temporarily carrying two housing debts. The prudent move is to price the deal assuming the old home takes longer to sell than you hope, and to confirm you could survive three to six months of overlap.
A bridge loan concentrates that risk into a hard deadline; a HELOC spreads it out but never stops charging interest. Neither is free, and neither removes the underlying exposure of owning two homes at once.
The bottom line
Open a HELOC on your current home if you are planning your move at least a month ahead of listing: it is the cheaper, more flexible tool, and you draw only what you need. Choose a bridge loan if you have already listed, if your equity is strong but your monthly income would not qualify you for a HELOC, or if you need a certain lump sum fast to win a competitive California offer. The decision is made almost entirely by timing and qualification, not by which product sounds better.
