What is a bridge loan in real estate?
A bridge loan is temporary financing that carries a property from where it is today to where a permanent lender will finance it. On apartment buildings, that usually means a building with high vacancy, dated units or weak management that won’t yet qualify for a Fannie Mae, Freddie Mac or HUD loan.
The business plan is the reason the loan exists. The sponsor buys, renovates, raises rents and pushes NOI up, then pays the bridge loan off with a refinance or a sale. If that plan works, the bridge loan is a means to an end. If it stalls, the short term becomes a deadline.
How a bridge loan works on an apartment building
Most multifamily bridge loans share the same building blocks, even when lenders label them differently. Read the term sheet for each one, because the details decide how much cash you’ll need and how much time you really have.
- Interest-only payments: you pay interest on the amount drawn, not principal, which keeps payments low while income is down.
- Floating rate: the rate is usually a spread over an index such as Term SOFR or 30-day Average SOFR, so the payment moves every month with the index.
- Initial term plus extensions: a short initial term with one or more extension options, each usually conditioned on tests such as a minimum DSCR or debt yield, no default and an extension fee.
- Renovation holdback: part of the loan is held back and released in draws as work is completed and inspected.
- Interest reserve: money set aside at closing, from the loan or from equity, to pay interest while the building’s income can’t cover it.
- Rate cap: a purchased interest rate cap that limits how high the index can push your payment.
- Fees: origination at closing, and often exit or extension fees spelled out in the loan documents.
How SOFR rate caps work on floating-rate loans
An interest rate cap is a contract that pays you when the index rises above a set strike rate, which limits the rate you effectively pay on a floating loan. You buy it upfront from a cap provider the lender approves, usually for the initial term of the loan, and the lender holds it as collateral.
The cap has three parts: the notional amount (usually the loan amount), the strike (the index level where payments kick in) and the term. If SOFR sits above the strike, the provider pays the difference on the notional, and that payment offsets the higher interest. Your total rate is capped at the strike plus the loan’s spread.
Caps cost more when rates are high, volatile or expected to rise, and when the strike is close to the current index. Lenders often require you to buy a replacement cap before extending, and some make you escrow monthly for it. Fannie Mae’s structured ARM term sheet, for example, requires the borrower to buy a cap from an approved provider and escrow monthly for the next one when the loan outlasts the cap. Price the replacement cap into your extension math, not just the first one.
How bridge loans are sized: loan-to-cost and as-stabilized value
Bridge lenders size the loan on the total project cost and on what the building should be worth once the business plan is done, and you get the lower of the tests. Loan-to-cost (LTC) is the loan divided by purchase price plus renovation budget, and sometimes closing costs and reserves.
Loan-to-stabilized-value compares the loan with the appraiser’s as-stabilized value, which assumes the renovations are finished and the units are leased at the new rents. Many lenders also check debt yield, which is NOI divided by the loan amount, on today’s income and on projected income. Debt yield matters because it doesn’t depend on the interest rate, so it shows how the loan will look to the next lender.
A high LTC doesn’t mean a cheap deal. The more the loan relies on future NOI, the less room you have if rents come in short or the renovation runs late.
Hard money lender vs bridge lender vs debt fund vs bank
Hard money lenders, bridge lenders, debt funds and banks can all fund a transitional apartment deal, but they price risk and set terms differently. The labels overlap, so judge each lender on its term sheet and track record, not the name.
| Lender | How it usually works | Often fits |
|---|---|---|
| Hard money lender | Private or individual capital, asset-focused underwriting, fast closings, often fixed rate with points | Small buildings, quick closes, rough properties |
| Bridge lender | Institutional loan programs, floating rate over SOFR, holdbacks, extension options | Value-add buildings with a clear refinance plan |
| Debt fund | Investor capital deployed as loans; some fund larger, heavier renovations and hold the loan or finance it through a CRE CLO | Larger deals and complex business plans |
| Bank or credit union | Balance-sheet loans, often recourse, relationship driven, may want deposits | Experienced local sponsors and lighter renovations |
Are bridge loans covered by the Truth in Lending Act?
Most bridge and hard money loans on apartment buildings fall outside the Truth in Lending Act’s consumer rules because they are business-purpose credit. Regulation Z exempts credit extended primarily for a business or commercial purpose and credit extended to anyone other than a natural person, such as an LLC, under 12 CFR 1026.3(a).
The CFPB’s official commentary goes further: credit to buy, improve or maintain rental property that isn’t owner-occupied is deemed business purpose, regardless of the number of units. That’s why consumer disclosures, ability-to-repay rules and many fee limits don’t apply. State usury and licensing laws still can, and they vary, so your lender’s counsel and yours should check them.
Worked example: $4 million purchase plus $800,000 renovation
A sponsor buys an apartment building for $4,000,000 with an $800,000 renovation budget, so total cost is $4,800,000. The lender offers 75% loan-to-cost, or $3,600,000. It funds $2,800,000 at closing (70% of the price) and holds back $800,000 for renovation draws. The sponsor brings $1,200,000 of equity plus closing costs.
To keep the math simple, assume a 9.0% interest-only rate and a 1% origination fee of $36,000. If the renovation draws come in evenly over 12 months, year-one interest is about $291,000. Once the full $3,600,000 is drawn, interest runs $27,000 a month, or $324,000 in year two.
In-place NOI is $200,000 in year one, leaving a $91,000 shortfall that the interest reserve has to cover. If NOI reaches $300,000 in year two, another $24,000 is needed. That’s $115,000 of carry the sponsor must fund on top of the equity and the rate cap. Two years of interest total $615,000.
| Item | Calculation | Amount |
|---|---|---|
| Total project cost | $4,000,000 + $800,000 | $4,800,000 |
| Bridge loan (75% LTC) | $4,800,000 × 75% | $3,600,000 |
| Funded at closing | $3,600,000 − $800,000 holdback | $2,800,000 |
| Sponsor equity | $4,800,000 − $3,600,000 | $1,200,000 |
| Origination fee (1%) | $3,600,000 × 1% | $36,000 |
| Year-one interest | 9.0% on the balance as draws fund | About $291,000 |
| Year-two interest | $3,600,000 × 9.0% | $324,000 |
| Interest reserve needed | $91,000 + $24,000 shortfall | $115,000 |
Exit risk: refinancing a bridge loan into agency debt
The biggest risk on a bridge loan is the exit, because the refinance depends on NOI, cap rates and interest rates at a future date you don’t control. Run the exit at today’s numbers and at worse ones before you sign.
In the example, the sponsor plans an agency refinance at 75% LTV and 1.25x DSCR on a 30-year schedule. If stabilized NOI hits $372,000, the building is worth $6,200,000 at a 6.0% cap rate. At a 6.25% rate, the DSCR test allows about $4,027,823, which pays off the $3,600,000 bridge loan with about $427,823 left before refinance costs.
Now change three assumptions: NOI reaches only $340,000, the cap rate is 6.75% and the new loan costs 7.25%. Value falls to about $5,037,037, and the DSCR test allows only about $3,322,699. The sponsor now has to bring about $277,301 to refinance, sell, or extend and hope.
This isn’t theoretical. Between March 2022 and July 2023, the Federal Reserve raised its federal funds target range from 0–0.25% to 5.25–5.50%. Floating bridge payments jumped, replacement caps got far more expensive and higher permanent rates shrank refinance proceeds, which squeezed sponsors who had bought in 2021 and early 2022 on floating-rate debt.
| Exit test | Base case | Stress case |
|---|---|---|
| Stabilized NOI | $372,000 | $340,000 |
| Cap rate / value | 6.0% / $6,200,000 | 6.75% / $5,037,037 |
| 75% LTV limit | $4,650,000 | $3,777,778 |
| 1.25x DSCR limit | $4,027,823 at 6.25% | $3,322,699 at 7.25% |
| Versus $3,600,000 payoff | About $427,823 surplus | About $277,301 short |
How to lower the risk on a bridge loan
Exit risk is baked into every value-add deal and can’t be removed, but you can buy yourself time and margin. These levers matter most.
- Underwrite the refinance at a higher rate and cap rate than today’s, and size equity so the stress case still works.
- Negotiate extension tests you can realistically meet, and know the extension fee and replacement cap cost in advance.
- Fund the interest reserve fully, and keep separate working capital for vacancy and overruns.
- Prefer a longer initial term over a cheaper spread when the renovation is heavy.
- Check the prepayment and exit fee terms, so selling early is a real option.
- Keep a second exit in view, such as a sale, an assumable loan or a HUD 223(f) loan with longer amortization.
Bridge loans in a syndication: what passive investors should check
If you invest passively in a value-add apartment syndication, the bridge loan terms shape your risk as much as the property does. Ask for the term, extensions, rate cap strike and term, interest reserve and the refinance assumptions in the sponsor’s model.
A plan that only works if rates fall, or that assumes a cap rate lower than today’s, depends on the market more than on the sponsor. Look for the stress case and ask what happens to distributions and capital calls if the exit slips a year.
