If you want to buy your next home before your current one sells, the two financing tools most homeowners hear about are a bridge loan and a home equity line of credit (HELOC). Both use the equity in the home you already own. They differ in how money is released, how long it lasts, what lenders allow once your home is listed, and how expensive a slow sale can become.

This guide compares the two for an owner-occupant moving up or across town. It does not quote current rates, because pricing changes daily and varies by borrower; use the framework below and get written quotes.

What each tool is designed to do

A bridge loan is short-term financing secured by your current home (and sometimes the new one) that is meant to be repaid when the current home sells. Terms are usually measured in months, not years, and some bridge products allow interest to accrue or be paid at payoff rather than monthly. Availability, structure and fees vary widely by lender.

A HELOC is a revolving line of credit secured by your home. The CFPB describes a draw period during which you can borrow and repay, followed by a repayment period; many HELOCs carry a variable rate tied to an index. You can draw what you need for a down payment and repay the line from your sale proceeds.

Confirm every row with the specific lender. These are structural differences, not guaranteed terms.

Listing status and lender approval limits

Timing matters more with a HELOC, and two separate questions apply:

  • Opening a new line after you list. Whether a lender will approve a new HELOC on a home that is already listed for sale is a matter of that lender's product policy. Some lenders do not; ask in writing before you list and plan the application before the listing date.
  • Keeping an existing line available. Once a line is open, federal rules limit when a lender can freeze it or reduce the limit to specific conditions, such as a significant decline in the home's value, or a material change in your financial circumstances that leads the lender to reasonably believe you will be unable to meet the repayment obligations under the plan, as written into your agreement (Regulation Z, 12 CFR 1026.40). Listing the home is not, by itself, one of those listed conditions, but read your agreement and ask the lender how it applies to you (CFPB: HELOCs).

A bridge loan is designed for the listed-home situation, but the lender will still review your credit, income, equity and the marketability of your current home. Neither tool removes underwriting for the new mortgage.

Carrying two homes: qualification, cash and a slow sale

The new-home lender decides whether your current housing payment and the bridge or HELOC payment count against your debt-to-income ratio. Do not assume either payment will be excluded; ask for the lender's treatment in writing.

  • Cash reserve: plan for two mortgages, two sets of utilities, insurance, taxes and HOA dues for longer than you expect.
  • Sale delay: if the current home sells later or for less than planned, a bridge term can expire or a variable HELOC payment can rise.
  • Offer strength: removing a home-sale contingency can make an offer cleaner, but it moves the risk of a slow sale onto you. It does not guarantee your offer is accepted.

If you prefer to keep a sale contingency, our home sale contingency guide for Washington explains how that route works.

Scenario: comparing total cost with stated assumptions

The numbers below are hypothetical inputs for illustration only, not current market quotes. Replace every value with the written terms each lender gives you. For a bridge loan, ask the lender which disclosure applies to that product. A HELOC is an open-end line of credit and does not come with a Loan Estimate (CFPB: loans that do not receive a Loan Estimate); use the HELOC disclosures, the fee list and the line agreement instead.

Assumption (hypothetical)Bridge loanHELOC
Amount borrowed$200,000$200,000 drawn
Annual rate used for the example9.0%8.0%
Upfront fees used for the example$4,000$1,000
Interest over 4 months (simple)$6,000$5,333
Interest over 9 months (simple)$13,500$12,000
Financing-cost subtotal at 4 / 9 months (interest + upfront fees only)$10,000 / $17,500$6,333 / $13,000

Simple interest = amount x rate x months / 12. The example assumes the full $200,000 is outstanding the whole time at a constant rate with interest-only cost; a variable HELOC rate, partial draws or required principal payments would change it.

This table is only a financing-cost subtotal. It is not the total cost of moving. Estimate these separately, and if your mortgage payment already includes an escrow for taxes and insurance, do not count those again:

  • Payments on both homes while you own both (principal and interest, plus taxes and insurance only if not already in the payment)
  • Utilities, HOA dues and upkeep for the home you are leaving
  • Bridge extension fees, or HELOC early-closure or annual fees
  • Any rate change on a variable line during the months you carry it

The point is not which tool wins; it is that months of carrying time often matter more than the headline rate. Also price the cost of the alternative: selling first and renting or using a rent-back.

Documents and conditions to confirm before you sign

  • Bridge loan: the lender's written terms and whichever disclosure applies to that product
  • HELOC: the HELOC disclosures, fee list and line agreement (a HELOC does not receive a Loan Estimate)
  • Whether the lender will open a new HELOC on a listed home, and the conditions in your agreement under which an existing line can be frozen or reduced
  • Bridge term length, extension options and cost of extension
  • Whether payments are monthly or due at payoff
  • Index, margin, rate caps and any minimum draw for the HELOC
  • How the new-home lender counts both payments in your DTI
  • Prepayment or early-closure fees
  • A realistic sale timeline and price range for your current home

Frequently asked questions

Is a bridge loan the same as a cash offer?

No. It can let you make an offer without a home-sale contingency, but the new mortgage still has its own financing terms unless you are paying entirely in cash. Sellers evaluate the full contract.

Can I get a HELOC after I list my home?

That depends on the lender's product policy; some lenders do not open new lines on listed homes, so ask in writing before listing. An existing line is a separate question: it can be frozen or reduced only under conditions allowed by federal rules and stated in your agreement, for example a significant decline in the home's value, or a material change in your finances that leads the lender to reasonably believe you cannot meet the repayment obligations.

Which one is cheaper?

It depends on fees, rate, and especially how long you carry the debt. Compare each lender's written terms using several sale-timing scenarios, and remember the financing cost is only one part of the cost of owning two homes.
