Commercial bridge loans

When a bridge loan is the right tool

A permanent lender sizes a loan on income the property earns today. A bridge lender sizes on what the property will earn after a plan works. That makes bridge debt the tool for:

• buying a building with vacancy, below-market rents or deferred maintenance;
• funding a renovation or lease-up that a permanent lender will not touch until it is done;
• refinancing a maturing loan on a property whose income dropped and will recover;
• closing fast on a purchase, then refinancing at leisure.

It is the wrong tool for a property that is already stabilized. That owner pays a bridge price for no reason.

Who lends: debt funds and mortgage REITs make most institutional bridge loans (see debt fund loans for how they structure them), banks make bridge loans to borrowers they know, often with recourse, and private lenders cover the fast and the messy end (see hard money loans). The comparison of debt fund vs bank bridge goes deeper on that choice.

Worked example: bridge to agency takeout

Illustration only. Every figure below is an assumption, not a quote.

An investor buys an 80-unit apartment building for $12,000,000. In-place NOI is $600,000. The plan spends $1,500,000 renovating units over 18 months, with stabilized NOI projected at $1,020,000.

The bridge loan. The lender commits 75% of total cost: ($12,000,000 + $1,500,000) x 0.75 = $10,125,000. It advances $8,625,000 at closing and holds $1,500,000 as future funding for the renovation, drawn as work is done.

The carry problem. At an assumed 7.15% coupon, interest on the initial advance is about $617,000 a year, more than the $600,000 of in-place NOI. Once the renovation money is drawn, interest on the full $10,125,000 is about $724,000. The lender will require an interest reserve funded at closing to cover the shortfall until rents rise. Budget it as part of the equity.

The exit test. At stabilization the investor refinances into a permanent loan. Assume the takeout lender sizes at 1.25x coverage (Fannie Mae’s conventional floor is 1.25x min DSCR³), a 6.25% rate and 30-year amortization:

Takeout scenario	Stabilized NOI	Takeout rate	Maximum permanent loan at 1.25x	Pays off $10,125,000?
Plan works	$1,020,000	6.25%	$11,044,000	Yes, about $919,000 to spare
Rates rise	$1,020,000	7.00%	$10,221,000	Barely, before closing costs
Rents fall short	$950,000	6.25%	$10,286,000	Barely, before closing costs
Both	$950,000	7.00%	$9,519,000	No: about $606,000 short

This table is the whole bridge decision. If the “both” row would sink the deal, the plan needs more equity, a smaller loan or a lender with longer extensions. Run your own version in the refinance gap calculator, and read the bridge-to-agency situation guide for what agency lenders want to see at takeout.

Costs beyond the coupon

Cost	How it works
Origination fee	Points at closing, usually on the full commitment
Exit fee	Points at payoff; some lenders waive it if they make the permanent loan
Extension fee	Paid each time you exercise an extension option
Rate cap	Bought at closing and often again at each extension
Interest reserve	Your cash, held by the lender, to cover the carry
Third-party reports	Appraisal (as-is and as-stabilized), environmental, property condition, construction budget review

The gap between a lender’s cash coupon and its all-in yield is the fee load. The largest public book reported a cash coupon of +3.08% over floating benchmark rates (mostly SOFR)⁴ and an all-in yield of +3.43%⁴, so fees added about a third of a point a year across that book.

Prepayment

Bridge loans expect to be repaid early, so the penalty is short. Most carry a minimum-interest period (the lender earns a set number of months of interest even if you repay sooner), then open prepayment, and many add an exit fee. Read whether minimum interest is charged on the funded balance or on the full commitment; on a loan with large future funding that difference is real money.

What bridge lenders check

1. The plan and the budget. Unit renovation scope, cost per unit, contractor, schedule and the rent premium the market supports.
2. The exit. A takeout sized at today’s permanent terms, not the best case, as in the table above.
3. Sponsor experience with the same property type and plan, and liquidity to fund the reserve and overruns.
4. As-is and as-stabilized value from the appraisal; the loan must make sense on both.
5. Extension tests. Debt yield, coverage or LTV hurdles at each extension date, and whether the plan reaches them in time.

Common deal killers

• No credible takeout. If the permanent loan does not cover payoff at realistic rates, the bridge lender will cut proceeds.
• Carry not budgeted. Sponsors run short of cash mid-plan when the interest reserve is too small.
• Extension tests missed because lease-up runs a few months long. That is how good plans end in a forced refinance.
• Unhedged rate risk. A cap that expires before the loan does leaves the property exposed.
• Overstated rent premiums on renovated units, the most common reason stabilized NOI misses.

Where it wins and where it loses

Bridge loans win on speed, leverage on the plan and flexibility to prepay. They lose on cost and on risk: floating rates, short terms and extension tests put the sponsor’s timeline on a clock. Once the property stabilizes, move it to Fannie Mae, Freddie Mac, a bank or CMBS. Commercial mortgages maturing in 2026 totaled $875 billion, 17% of $5.0 trillion outstanding⁵ per MBA, and many of the properties behind them will pass through a bridge loan before they reach permanent debt again.
