When a rate cap expires mid-hold, the bridge loan math inverts fast

The 400k loss is a sequencing problem, and the assumption doing the most work is that the business plan timeline and the rate cap term were the same number. They were never the same risk. The business plan is the optimistic case. The cap needs to cover the realistic case plus a margin for the delays that show up on almost every value-add: permit holds, contractor scheduling, a slow appraisal, a lender's underwriting queue.

The structural error is treating the cap expiry as a soft deadline. Once the cap expires on a floating-rate bridge loan with SOFR at 4.8, the carry cost is no longer a rounding error in the waterfall, it is eating into the refi proceeds before the refinance even closes. The DSCR floor fails because the trailing income looks worse at the higher in-place rate, and the appraisal gap that the buffer was supposed to absorb has already been consumed by carry. The sequence collapses from the inside.

The 90-day clearance question you raised is the right frame, but 90 days assumes a clean refi process. Agency execution on a stabilized asset can run longer if there is any noise in the rent roll or if the appraiser comes in light on value. Some allocators working with bridge lenders on value-add multifamily are sizing caps to clear the projected refi date by 120 to 150 days, and some are buying extension optionality on the cap itself at origination rather than at month 17 when it is expensive. Confirm the specific cost and availability of that extension feature with your lender in writing, because it varies by cap provider and market conditions.

The risk this post does not name: the LP capital call at month 19 is a relationship event, not just a financial one. A capital call after the timeline has already slipped changes LP behavior on the next deal.

What does your current cap term look like relative to the projected stabilization date, before the refi application even goes out?

On my Elk Grove duplex refi last year, the appraisal alone took 11 weeks when the lender quoted four.

That 90-day buffer number is too thin if your market has any appraisal backlog at all. I would not go under six months past projected refi close, not after what I saw. What does your contractor's draw schedule look like at month 18, because that is usually where the real slip happens?

The cap term is the deal's hidden critical path, and almost nobody builds the extension scenario into their initial underwriting.

Take a 24-month business plan where the realistic delay distribution on a value-add of that size runs three to five months for permitting, two months for contractor slippage, and another two for the appraisal queue. That is a seven to nine month exposure window sitting outside the business plan timeline before you even account for DSCR seasoning requirements that most agency lenders want to see for 90 days of stabilized occupancy. So the cap that matches a 24-month plan actually needs to cover roughly 33 months to give the refi a clean runway, and the cost difference between an 18-month cap and a 30-month cap at purchase is usually modest compared to one month of unhedged carry at the spread described above.

The number doing the most work in this scenario is not the exit basis or the renovation budget. It is the assumption that the refi approval timeline is frictionless, which it never is when the appraisal is already being squeezed by a tightening DSCR floor.

A structure worth comparing: some sponsors buy the shorter cap and include a contractual extension option at origination, which locks the strike and term at a price set when rates and volatility are lower. That beats repricing in an open market 18 months later when SOFR has moved and cap premiums have widened with it.

What is the bridge lender's position on a cap extension option baked into the loan docs at closing, and have they quoted the premium difference?

The cap cost itself is worth modeling as a variable, not a line item you accept from the broker's term sheet.

Take a 6.2 million bridge loan where a 24-month cap costs 180k and an 18-month cap costs 90k. The 90k savings looks clean until month 19 delivers 8.3 percent all-in on a loan that was underwritten at 5.5. At 48 units averaging 1,300 a month gross, the carry gap from that single rate jump runs roughly 14k a month in extra interest. Six months of that is 84k, which nearly erases the cap premium you saved. The syndicator in the original example did not save money buying the shorter cap, they borrowed against timeline certainty and lost.

The piece I want to add to what is already in this thread: the cap strike price deserves as much attention as the term. A cap struck at 2 percent SOFR when SOFR is already moving toward 3 gives you less real protection than the nominal ceiling suggests, because the in-the-money distance shrinks fast and the premium you paid reflects a floor that the market had already partially priced. A cap struck well above current SOFR on a short term can be cheaper and still leave you naked exactly when the loan is most vulnerable.

The question worth asking your lender before you price the cap: does the extension option on the bridge loan require a new cap purchase, and if so, at what strike and term, because that second cap purchase at elevated rates can cost more than the first one did.

What is the extension language on the bridge you are looking at, specifically whether the extended term requires a fresh cap or accepts an endorsement on the existing one?

The risk nobody named: if the cap provider is a small counterparty without a high credit rating, the cap may not perform even while it is still nominally in effect, because the payout depends on the counterparty's ability to fund it when SOFR spikes hardest.

My Dayton STR refi last year took 4 months longer than underwritten because one appraiser quit mid-process.
