How a Bridge Loan Actually Works
Program and regulatory figures verified September 25, 2026. Details change; confirm your scenario with us.
A bridge loan is a short-term loan against equity you already have, repaid from the sale of the home you are leaving. Everything else follows from that sentence.
The mechanic
You own a home with equity. You want to buy the next one before that equity is liquid. A bridge loan advances against the equity now so it can serve as a down payment, and it is repaid when the sale closes.
Because the exit is a sale rather than a payment schedule, the underwriting question differs from an ordinary mortgage. The lender is assessing whether the departing home will sell, at roughly what value, and in roughly what timeframe.
What it is not
A bridge loan is a loan. No lender is buying your home, nobody is promising it will sell, and nothing here puts a floor under your sale price. If the departing home sells for less than expected, that outcome is yours.
Where the cost sits
- Closing costs on the bridge itself, incurred for a loan you intend to hold briefly.
- Carrying cost while both properties are in your name.
- Reserves, less a cost than a liquidity requirement, and the constraint most files actually meet.
- The tax picture at the exit, which in Massachusetts can reduce what the proceeds are actually worth to you.
We do not publish rate or pricing information on these pages. Pricing depends on the file.
The two alternatives
Carrying both payments and recasting afterward avoids a second lien. You qualify holding both, then apply net proceeds to principal and re-amortize, lowering the payment without a refinance.
Converting the departing home to a rental removes the timing dependency and, in Massachusetts, realises no capital gain in the current tax year. Under Fannie Mae B3-3.8-05 the rental income can offset that property's own payment though it never adds qualifying income. See the Form 1007 page.

Frequently asked questions
How does a bridge loan get repaid?
From the sale proceeds of the home you are leaving. The loan is short-term by design and the exit is the sale, which is why underwriting evaluates the departing home's expected value and marketing time rather than only your income.
Is a bridge loan the same as a company buying my house?
No. A bridge loan is a loan against equity you already own. No lender purchases your home and no sale price is promised.
What usually stops a bridge loan from working?
Reserves, more often than income. Lenders tier reserve requirements against how long homes are taking to sell in the relevant market, so a slower submarket increases the months required.
What are the alternatives to a bridge loan?
Qualify carrying both payments and recast the new loan after the sale, or convert the departing home to a rental where Fannie Mae B3-3.8-05 lets the rent offset that property's payment. In Massachusetts the rental route also realises no gain in the current tax year.
