Key Takeaways
- Interest rate risk is the single largest macro risk in commercial real estate — a 200 basis point rate increase can reduce levered equity returns by 30–50% and cut property values by 10–20% through cap rate expansion
- The 2022–2024 rate cycle destroyed billions in CRE equity, primarily affecting operators who used floating-rate bridge debt without adequate hedging. Fixed-rate borrowers were largely insulated
- Debt structuring isn't about finding the cheapest rate — it's about matching the debt profile to the business plan. Fixed-rate for stabilized holds, floating-rate with mandatory rate caps for short-term value-add execution
Between 2020 and 2022, commercial real estate operators could borrow at 3–4% on floating-rate bridge loans and underwrite to a refinance at similar rates. By late 2023, those same loans had reset to 8–9%. Debt service payments doubled. Refinance proceeds that were modeled to return investor capital couldn't even cover the outstanding loan balance. Capital calls went out. Properties were sold at losses. Sponsors who had built multi-billion-dollar portfolios in the low-rate era were returning partial capital — or nothing at all.
That's not a market downturn story. It's a debt structure story. The properties were still standing. The tenants were still paying rent. The NOI was often meeting or exceeding projections. What broke wasn't the real estate — it was the capital stack.
Understanding Interest Rate Exposure
Interest rate risk in CRE manifests in three distinct ways, each requiring a different mitigation strategy:
| Risk Type | Mechanism | Impact |
|---|---|---|
| Payment Risk | Floating-rate debt service increases as benchmark rates rise | Direct reduction in cash flow to equity; potential DSCR covenant breach |
| Valuation Risk | Rising interest rates push up cap rates, reducing property values | Reduced exit proceeds; negative leverage on refinance; LTV covenant breach |
| Refinance Risk | Loan maturity in a higher-rate environment with tighter lending standards | Cash-in refinance; forced sale; extension at unfavorable terms |
The dangerous part? All three risks compound simultaneously. When rates rise, your payments increase (payment risk), your property is worth less (valuation risk), and your ability to refinance is constrained (refinance risk). This is exactly what happened to the 2021–2022 vintage multifamily deals that fueled some of the largest write-downs in CRE history.
Fixed vs. Floating: The Core Decision
Every CRE debt decision starts with one fundamental question: fixed or floating? The answer should be driven entirely by the business plan — not by the rate environment.
When Fixed-Rate Debt Makes Sense
Fixed-rate debt is the right choice when the business plan calls for a stable, predictable hold period. If you're acquiring a stabilized property and plan to hold for 5–10 years, fixed-rate debt eliminates payment risk entirely. You know exactly what your debt service will be for the entire hold period, which means your cash-on-cash returns are predictable and your distributions to investors are reliable.
The trade-off is the premium: fixed-rate debt typically costs 50–100 basis points more than the initial floating rate, and it comes with prepayment provisions (defeasance or yield maintenance) that make early payoff expensive. But for a buy-and-hold strategy, that predictability premium is almost always worth paying.
When Floating-Rate Debt Makes Sense
Floating-rate debt is appropriate for short-term business plans where the exit or refinance is expected within 12–36 months. Value-add acquisitions that involve significant renovation and re-leasing before stabilization often use floating-rate bridge loans because: (1) fixed-rate lenders won't lend against unstabilized properties, (2) bridge lenders will finance renovation budgets through future-advance structures, and (3) the borrower expects to refinance into permanent fixed-rate debt once the property is stabilized.
The critical requirement for any floating-rate strategy is a rate cap — a financial instrument that limits the maximum interest rate the borrower will pay. Without it, a 300 basis point rate increase on a $10M floating-rate loan translates to $300,000 in additional annual debt service — money that comes directly out of investor returns.
A rate cap is essentially an insurance policy against rising interest rates. The buyer pays an upfront premium (think of it as the insurance premium) and sets a "strike rate" (the maximum rate they're willing to pay). If the benchmark rate (SOFR) exceeds the strike rate, the cap seller pays the buyer the difference.
Example: A borrower has a $10M floating-rate loan at SOFR + 250bp. They purchase a 2-year rate cap with a 4.00% SOFR strike for $65,000. If SOFR rises to 5.50%, the cap pays the borrower 1.50% × $10M = $150,000/year, effectively keeping their all-in rate at 6.50% (4.00% + 2.50% spread) instead of 8.00% (5.50% + 2.50%).
Rate cap pricing varies dramatically based on: (1) the current rate environment vs. the strike rate, (2) market volatility expectations, (3) the cap term, and (4) the notional amount. In early 2022, a 2-year 3% SOFR cap on $10M cost about $15,000. By mid-2023, the same cap cost $250,000+ — a direct result of rate volatility and the expectation that rates would remain elevated.
Most floating-rate CRE lenders now require rate caps as a condition of the loan. The cap must cover the full loan term (or include a replacement cap requirement), and it must be assigned to the lender as additional collateral.
The Refinance Trap
Refinance risk is the silent killer in CRE. Unlike payment risk (which is immediate and visible), refinance risk builds slowly and only materializes when the loan matures — often at the worst possible time.
Here's a typical scenario that played out across thousands of CRE deals in 2023–2024:
Refinance Risk — A Real-World Scenario
Acquisition: 80-unit multifamily, $12M purchase price, June 2021
Original Loan: $9.6M bridge at SOFR + 300bp (all-in 3.10%), 3-year term
Business Plan: $1.5M renovation → raise rents 25% → refinance at stabilized value of $15M
Projected Refinance (2024): $15M value × 70% LTV = $10.5M proceeds → repay $9.6M → return $900K to investors
Actual Refinance (2024):
NOI hit projections: $960,000 (as underwritten)
But cap rates expanded from 4.5% to 5.8%
Actual Value: $960,000 ÷ 5.8% = $16.55M → sounds fine
New DSCR Requirement: 1.25x at 6.5% fixed rate
Max Loan Based on DSCR: $960,000 ÷ 1.25 ÷ 7.2% constant = $10.67M
But new LTV requirement: 65% × $16.55M = $10.76M
Binding Constraint (lower of DSCR/LTV): $10.67M
Outstanding Bridge Balance (with extension fees): $10.1M
Net Refinance Proceeds: $10.67M − $10.1M = $570K → no capital return to investors
The renovation worked. The rents went up. The NOI hit projections. But the rate environment shifted the math entirely — turning a projected $900K capital return into a $570K trickle that barely covered closing costs.
How to Manage Interest Rate Risk in CRE
Our debt structuring philosophy is built around one principle: don't bet on rates. We don't know where SOFR will be in 2028, and neither does anyone else. Our job is to structure deals that work regardless of the rate environment. Here's how:
Default to fixed-rate debt. For stabilized acquisitions with hold periods over 3 years, conservative operators use agency fixed-rate loans (Fannie Mae, Freddie Mac) or CMBS fixed-rate products. Yes, we pay a premium. Yes, the prepayment provisions limit flexibility. But the certainty is worth the cost — sponsors can tell investors exactly what cash-on-cash yield to expect for the next 7 years, and rate movements won't change that number.
Mandatory rate caps with substantial coverage. When we do use floating-rate debt (which is rare and limited to short-term value-add execution), we purchase rate caps that cover the full loan term plus any extension options. Our caps are struck at rates that maintain a minimum 1.25x DSCR even at the capped rate — not at the cheapest available strike.
Conservative underwriting assumptions. We underwrite exit cap rates 50–75 basis points above the going-in rate. We stress-test every deal at a refinance rate 100 basis points above current market. And we don't model any interest rate declines into our projections — if rates drop, that's upside, not part of the base case.
The operators who lost the most money in the 2022–2024 rate cycle weren't bad at real estate. They were bad at risk management. They treated debt structure as an optimization problem — finding the cheapest rate — instead of a risk management problem: ensuring the deal survives regardless of what rates do.
Match debt term to hold period. We never take a 3-year loan on a 7-year hold. That creates a mandatory refinance event in the middle of the business plan — and if rates are unfavorable at that point, you're forced to accept whatever the market offers. Our rule: debt term must match or exceed the planned hold period.\
Interest rate risk isn't something you can eliminate — it's embedded in every levered real estate investment. But it is something you can structure around, price for, and mitigate through disciplined debt decisions. The sponsors who survived the 2022–2024 rate shock aren't the ones who predicted rates correctly — they're the ones who built capital structures that didn't require rates to cooperate. That's the standard disciplined operators should hold themselves to.
