Floating-Rate Bridge Debt and the Rate Cap That Expires
A derivative with an expiry date, bought at closing, protecting a loan whose term is longer and a business plan whose timeline is longer still. The gap is where the trouble sits.
A repositioning property usually cannot obtain permanent financing, because permanent lenders want an asset already performing to their standards. So value-add deals are financed with bridge debt: shorter, more expensive, and usually floating.
Floating means the interest rate is set as an index plus a spread, and the index moves. A lender will generally require the borrower to buy an interest rate cap — a contract that pays out when the index exceeds a strike rate, limiting the effective cost.
The cap has an expiry date. That date is the subject of this article.
The three timelines that do not match¶
A syndication with bridge debt runs three clocks, and they are deliberately different lengths.
| Clock | Typical relationship | Why |
|---|---|---|
| The rate cap | The shortest | Caps are priced by term; a longer one costs materially more at closing |
| The loan | Longer than the cap, with extension options | Extensions usually require performance tests the property may not meet |
| The business plan and hold | Longest of the three | Renovation, lease-up and stabilization take as long as they take |
The consequence is a renewal event inside the hold period, at which a new cap has to be bought at whatever it costs on the day.
Why the replacement is expensive precisely when it is needed¶
A cap's price reflects the market's expectation of the index over its term. When rates are low and expected to stay low, caps are cheap. When rates have risen, caps are expensive — and both conditions arrive at once.
This is the asymmetry that matters: the original cap was bought when caps were cheap, and the replacement is bought when they are not, because the same conditions that make the replacement necessary are the conditions that make it costly. A budget line sized at the original price is not a budget for the replacement.
Where the reserve does not cover it, the money comes from operating cash flow — which means suspended distributions — or from the investors, which means a capital call.
What a cap does and does not do¶
A cap limits the index, not the total payment. The spread continues regardless, so a capped loan is not a fixed-rate loan.
It also has no effect below the strike. A cap struck well above the rate at closing is inexpensive precisely because it is unlikely to pay out, and a deal relying on such a cap has bought less protection than the existence of a cap implies. The strike rate is therefore worth reading alongside the fact of the cap.
And a cap protects the borrower's payment, not the property's value. Rising rates that pass through to capitalization rates reduce what the asset is worth at sale, and no cap addresses that. See pro forma assumptions on the exit rate.
Where the cap shows up in the documents¶
Four places, and they are not the same place.
The sources and uses shows the cost of the original cap, usually inside financing costs. The debt terms section of the memorandum gives the index, the spread, the strike and the expiry. The risk factors disclose the consequence of expiry, frequently in a single sentence inside a block of generic financing risk. The pro forma shows what debt service the model assumes after the expiry date, which is where an optimistic assumption hides most comfortably.
Reading all four together is the check. A model assuming constant debt service across a period in which the cap expires has disclosed the risk in one document and declined to model it in another — both accurate, and the combination is the finding. See reading the risk factors.
The alternative and its cost¶
Fixed-rate debt removes this whole category of risk and brings its own.
It is generally more expensive at closing on a transitional asset, where it is available at all. It usually carries prepayment penalties — defeasance or yield maintenance — that make an early sale costly, which constrains the exit flexibility a value-add plan may need. And permanent lenders, including the agency programs, size loans on current income, which a repositioning property does not yet have.
So bridge debt is not a mistake. It is the instrument that fits the strategy, and its risks are the strategy's risks made explicit. What is worth resisting is treating the cap as though it removed them: it converts an open-ended exposure into a dated one, and the date is the thing to write down.
The related reading is refinance risk, which is the same problem arriving at the loan's maturity rather than the cap's expiry, and how syndications fail for where both sit in the sequence.

Questions readers ask
What is an interest rate cap?
A purchased contract that pays the borrower when a floating index exceeds a strike rate, limiting the effective interest cost. Lenders on floating-rate loans commonly require one.
Why does a rate cap expire before the loan?
Because caps are priced by term and a longer cap costs substantially more. Sponsors buy the shortest term the lender will accept, which keeps the closing cost down and creates a renewal event later.
What happens when a cap expires?
A replacement must be purchased, at whatever it costs on that day. Where rates have risen since the original was bought, the replacement can cost several times as much, and the money has to come from reserves, cash flow, or the investors.
Is fixed-rate debt always better?
No. Fixed-rate debt costs more up front, usually carries prepayment penalties, and can be difficult to obtain on a property that is not yet performing. Bridge debt exists because repositioning assets cannot get permanent financing.
What should I check in an offering?
Whether the debt floats, the index and spread, the cap strike rate and expiry date, how the expiry compares with the projected sale, and whether the reserve budget includes a replacement.
