Bridge Loans on Long Island and Across Downstate New York

I help homeowners on Long Island and across downstate New York buy before they sell, comparing bridge loans, home equity lines and other options from the lenders I work with.

A bridge loan is short-term financing, typically secured by the home you already own, used to supply cash for your next purchase before the current home sells. The sale proceeds then generally repay it. It lets a Long Island owner buy first and sell second, but the real test is whether your budget can carry two homes if the sale runs late.

Who a bridge loan tends to fit

A bridge loan tends to fit a Long Island owner with real equity and the income to carry two homes. Most of these should be true:

• You have real equity in your current home. Values have climbed: per OneKey MLS, August 2026 single-family medians were up 7.0% year over year in Suffolk, to $760,000, and 4.7% in Nassau, to $911,000.
• Your income can carry two homes for a stretch, since lenders usually count both.
• You need to move on a specific house, such as one in another part of Nassau or Suffolk, and can’t wait to sell first.
• Your current home should sell readily at a realistic price.

If a slow sale would strain your budget or your equity is thin, selling first is usually safer.

How a bridge loan works when you buy before you sell

Typically, a lender places a short-term loan on your current home, secured by its equity. You put the proceeds toward the cash the new home needs, a new mortgage covers the rest, and when the old home sells, the closing proceeds repay the bridge loan and any existing mortgage on that home. Structure, costs and repayment vary by lender, and not every lender offers bridge loans.

Regulation Z, the federal truth-in-lending rule, exempts qualifying temporary or “bridge” loans from the ability-to-repay requirements that apply to most mortgages, so your own math matters more.

Fannie Mae’s bridge loan rules

If your new mortgage is a conventional loan sold to Fannie Mae, its Selling Guide accepts a bridge (or swing) loan as a source of funds only if the bridge loan is not cross-collateralized against the new property and the lender documents that you can carry the payments on the new home, the current home and the bridge loan, plus your other obligations. Fannie Mae sets no limit on the bridge loan’s term. Individual lenders may add stricter requirements, known as overlays. The 2026 conforming limit for one unit is $1,209,750 on Long Island, in New York City and in Westchester, Rockland and Putnam. Above it, the new mortgage is a jumbo loan with lender-specific rules; see conventional and jumbo loans on Long Island.

How lenders count two housing payments

Underwriters measure affordability with your debt-to-income ratio (DTI): monthly debts, housing included, against gross monthly income. Under Fannie Mae’s guide, if your current principal residence is pending sale but won’t close before your new loan, the lender must count both the current and the proposed PITIA, Fannie Mae’s term for the full monthly housing expense, including principal, interest, taxes, insurance and any association dues.

The exception: Fannie Mae doesn’t require the current home’s PITIA to be counted if the lender gets the executed sales contract and confirmation that any financing contingencies have cleared. So the timing of your buyer’s loan commitment can change what you qualify for. Other programs and lenders may apply different standards.

Long Island property taxes count twice here, and they vary widely across Nassau and Suffolk. Many bridge loans fund a local move, and my guides to selling and buying in Nassau County and moving across Suffolk County explain how assessments work in each county. Get the new home’s actual tax bill, then run both homes through the Long Island mortgage calculator.

Alternatives to a bridge loan

A home equity line of credit

Per the CFPB, a home equity line of credit (HELOC) is an “open-end” line you can draw on repeatedly before a repayment period begins. You draw what the purchase needs and pay it down when the old home sells. The CFPB’s cautions: rates are usually variable, payments are often significantly higher once repayment begins, and the lender may freeze or limit draws if your home’s value drops significantly or your finances change.

A cash-out refinance

This swaps your current mortgage for a larger one and pays you the difference. Since you plan to sell soon, closing costs weigh heavily, and the larger payment counts when you qualify for the new home. In New York a CEMA may limit recording tax to the new money if your current lender cooperates; see refinancing a mortgage on Long Island.

Sell first, then rent back

Selling first removes the two-payment problem. To avoid moving twice, some sellers negotiate to stay on after closing under a rent-back written into the sale contract; the attorneys set the terms, and the buyer’s lender may have its own requirements.

A contingent offer

An offer contingent on selling your home protects you from owning two, but sellers in a competitive market may prefer offers without that condition. Your attorney can explain how such a clause, and any mortgage contingency, would work.

Your own assets

Savings or investments can cover the gap; retirement money can carry taxes or penalties, so check with a tax professional first.

The risks, plainly

• Two housing payments, including Long Island property taxes on each, until the old home sells.
• A slower or smaller sale stretches the overlap and leaves less to repay the bridge.
• Costs on both ends: fees and closing costs on the bridge loan or line, plus closing costs on your new mortgage.
• Your current home is typically the security, and the CFPB warns that falling behind on a home equity line could cost you your home.

New York specifics: attorneys, two closings and taxes

An attorney on both deals

Plan on counsel for both transactions. The New York Attorney General advises using your own attorney, not one provided by the seller or the lender, to review contracts and loan documents before you sign, and with two deals in motion, both contracts need that review.

Timing two closings

If the sale closes first, there may be nothing to bridge; if the purchase closes first, you carry both homes. Back-to-back closings need attorneys, title companies and both lenders in sync, and a delay in your buyer’s loan or a co-op board review can push your sale back.

Closing taxes

Buying before you sell makes you a seller and a buyer at once. New York charges a mortgage recording tax when your new mortgage is recorded, and other taxes can apply at each closing; your Loan Estimate and closing attorney show the exact amounts. Ask your attorney how the recording tax applies to a bridge loan or credit line on your current home.

Buying before you sell in New York City and Westchester

Buying a New York City co-op: the board counts both homes

If the home you’re buying is a co-op, the board runs its own review. Many set their own limits on debt and on cash left after closing, and a bridge loan or second payment counts. If the home you’re selling is a co-op, its board has to approve your buyer, which can push your sale back.

Westchester, Rockland and Putnam

Two homes means two tax bills, and Westchester’s run high, so get each home’s actual bill. Co-ops are common here too, and the same board review applies.

Bridge loans for investors

Investors sometimes use “bridge” for short-term financing on a property they won’t live in. Under Regulation Z commentary, credit for rental property the owner doesn’t occupy is business-purpose credit, so different rules apply. See investment property financing on Long Island and, for long-term rentals, DSCR loans on Long Island.

Step by step: buying before you sell

1. Price your home honestly from recent comparable sales, and decide how long you could carry both homes.
2. Run the two-home budget: PITIA on both homes, bridge or line costs, other debts and cash for the overlap.
3. Compare routes and get preapproved. I check what the lenders I work with offer for your situation. The credit check for preapproval is only a soft one, so it won’t affect your credit score. A preapproval letter is not a final loan offer, and the CFPB notes it can expire.
4. Bring in your attorney before you sign either contract.
5. Send me your buyer’s signed contract once their financing contingency clears; it can change how your current payment is counted.
6. Close and pay off the bridge loan or line from the sale proceeds.

I arrange financing rather than lend it: the bridge loan, credit line or new mortgage comes from one of the lenders I work with. We can plan both transactions together.
