Bridge Loans in California: How to Buy a Home Before You Sell Yours

By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.

To buy before you sell in California, you generally need one of four tools: a bridge loan secured by your current home, a home equity line of credit (HELOC) opened before you list, an offer contingent on the sale of your home, or a sale with a rent-back so you can stay put while you shop. Each one trades cost, risk and offer strength differently, and the biggest risk in the first two is carrying two housing payments if your current home takes longer to sell than planned.

Below is how each option works, how lenders count your existing home when you qualify, and the questions to settle before you commit. We do not quote rates; get current terms in writing from lenders.

The four ways to bridge the gap

Bridge loans

A bridge (or "swing") loan is short-term financing secured by the home you already own, used to fund the down payment and costs on the new one, and repaid when the old home sells.

What Fannie Mae allows when your new mortgage is conventional. The Fannie Mae Selling Guide, B3-4.3-14 treats a bridge loan as an acceptable source of funds for the purchase, with conditions:

• The bridge loan cannot be cross-collateralized against the new property.
• The lender must document that you can carry the payments on the new home, your current home, the bridge loan and your other obligations.
• Fannie Mae sets no specific limit on the bridge loan’s term; the bridge lender sets its own.

How your current home’s payment is counted. Under Selling Guide B3-6-06 (topic dated 09/02/2026), if your current principal residence is pending sale but will not close before the new purchase, the lender counts both housing payments (principal, interest, taxes, insurance and association dues) when qualifying you. The exception: if you provide the executed sales contract on the current home and confirmation that the buyer’s financing contingencies have cleared, the lender does not have to count that payment.

That rule is why a buyer with strong income but a slow-selling current home may qualify for a bridge loan, while another buyer cannot. Jumbo and portfolio lenders set their own rules, which can be stricter.

Questions to ask a bridge lender:

• What is the maximum combined loan-to-value on my current home, and how is the value set?
• Are payments due monthly, deferred, or taken from the sale proceeds?
• What is the term, and what happens if my home has not sold when it ends?
• What fees apply, and are any refundable if I do not use the loan?
• Is there a prepayment penalty?

Compare at least two written offers. For a regular mortgage, the CFPB explains that a lender must give you a Loan Estimate within three business days of your application, on a standard form that makes side-by-side comparison easier. Ask each bridge lender which disclosure it will provide.

Using a HELOC as a bridge

Some owners open a HELOC on their current home before listing and draw on it for the next down payment. The CFPB’s booklet, What You Should Know About Home Equity Lines of Credit (updated August 2022), lays out the points that matter here:

• HELOCs usually carry a variable rate (an index plus a margin), so your payment can change even without new draws.
• The lender can generally freeze or reduce your line if your home’s value falls or your finances change, which could happen right when you need the money.
• When you sell the home, you generally must repay the HELOC in full.
• Costs can include appraisal, application and closing fees, and some plans charge annual, inactivity or early termination fees.
• Federal law gives you three days after opening to cancel the line in writing and receive a refund of fees paid.

Timing matters. Open the line well before you list, and ask the lender directly whether it will open or keep open a line on a home that is about to be marketed. The HELOC payment, like a bridge loan, will usually be counted when your new lender qualifies you.

Contingent offers

The lowest-cost approach is an offer contingent on selling your current home. The C.A.R. purchase agreement handles this through a separate addendum; our guide to the home sale contingency in California explains it in detail. In general terms, the seller can keep marketing the property and, if a better offer arrives, ask you to remove the contingency or step aside.

A contingent offer still needs a full loan contingency plan. And because your sale proceeds are the down payment, a delay on your sale delays your purchase. Listing your home first, or having it in escrow, makes a contingent offer more credible to sellers.

Selling first with a rent-back

Selling first removes the two-payment risk: you close, hold the cash, and become a non-contingent buyer. A seller rent-back lets you stay in the home after closing while you shop. Our guide to the seller rent-back in California covers the C.A.R. forms, how stays of 30 days or more change the legal relationship, and why your buyer’s lender occupancy rules can cap how long you stay.

The trade-off is pressure on the back end. If the rent-back ends before you find and close on your next home, you may need short-term housing and storage. Build that into your budget and timeline.

Risks to weigh before you commit

• Two payments. If the sale takes months longer than planned, you carry both homes, plus bridge or HELOC interest. Run the numbers at three and six months, not just one.
• Price risk on the old home. If you need a fast sale to retire the bridge loan, you may accept less. Start from a realistic home valuation and a seller net sheet.
• Variable cost. HELOC rates and many bridge loans float. Ask how a rate change would affect your payment.
• Taxes. A sale can trigger capital gains questions; see capital gains on a home sale in California. Your new home will also generate a supplemental tax bill. Owners 55 and older may be able to carry their assessed value to a replacement home under Proposition 19; the Board of Equalization says you can buy first if the original home sells within two years of that purchase. Read our Prop 19 base-year transfer guide and confirm timing with your county assessor before you sequence the two sales.
• Insurance and vacancy. If the old home sits empty while listed, confirm with your insurer how vacancy affects coverage.

California and county specifics

The financing rules above are national, but timing in our market varies by property type. Rural parcels in Sonoma, Napa, Mendocino and Lake counties, homes with wells or septic, and properties in high fire hazard areas can need longer escrows for inspections and insurance, which lengthens the bridge period. Multifamily owners in Alameda, Contra Costa and Santa Clara counties selling a tenant-occupied property face different timelines again. When we plan a buy-and-sell for a client, we set the listing date, the offer strategy and the financing deadlines together. Start with our selling and buying teams so the two transactions are planned as one.

Questions people ask

What is a bridge loan on a house?

A short-term loan secured by your current home that funds the down payment and costs on a new home, repaid when the current home sells.

Can I qualify for a new mortgage while I still own my current home?

Often, but the lender will usually count both housing payments. On Fannie Mae loans, your current home’s payment can be excluded only if you provide the executed sales contract and confirmation that the buyer’s financing contingencies have cleared.

Is a HELOC or a bridge loan better for buying before selling?

It depends on cost, timing and lender terms. A HELOC can cost less to set up but is usually variable-rate and can be frozen or reduced. A bridge loan is built for this purpose but often has higher fees. Compare written offers for both.

Can a bridge loan be secured by the new home?

Not when the new mortgage is sold to Fannie Mae: its guide says the bridge loan cannot be cross-collateralized against the new property.

Do sellers accept contingent offers in California?

Some do, especially when the buyer’s home is already listed or in escrow. Sellers commonly keep marketing and can ask the buyer to remove the contingency if another offer comes in.

How long can I rent back after selling?

It is negotiated. Stays of 30 days or more generally create a landlord-tenant relationship, and your buyer’s lender may limit the length. See our rent-back guide.

Will I have to repay my HELOC when I sell?

Generally yes. The CFPB notes that you usually must repay the full balance when you sell the home.

Do you provide bridge loan rates?

No. Rates and fees change and depend on your finances. Get written terms from lenders and compare them.
