Insurance is the new cap rate.

Before Ian, commercial property insurance for a typical Florida strip center ran $0.80–$1.40 per square foot per year. After Ian, renewal quotes for comparable coverage arrived at $2.20–$4.50 per square foot — increases of 100–250% in a single policy cycle. For an asset underwritten at a 7% cap rate, the incremental insurance cost alone is sufficient to compress the effective yield by 80–150 basis points.

The magnitude of the increase is important, but the structural drivers behind it are more so. Florida's property insurance market was already stressed before Ian: Citizens Property Insurance Corporation, the state's insurer of last resort, had grown its commercial policy count by 40% between 2020 and 2022 as private carriers exited the state. Six private insurers became insolvent in 2022 alone. Ian did not create the crisis — it accelerated a retreat that was already underway.

The underwriting impact

In a standard retail acquisition model, insurance is typically budgeted as a stable percentage of gross revenue — 4–6% in non-catastrophe markets, 8–12% in Florida. Post-Ian, insurance in Florida should be modeled at 14–20% of gross revenue for windstorm-exposed assets, and the variance around that estimate is wide enough to change the sign of a deal's return profile.

Consider a 40,000-square-foot strip center generating $720,000 in gross revenue. Pre-Ian, insurance ran roughly $56,000 (7.8% of gross). Post-Ian, the same coverage costs $130,000–$160,000 (18–22% of gross). The difference — $74,000–$104,000 annually — flows directly to the bottom line and, at a 7% cap rate, translates to $1.1–$1.5 million in implied value destruction. This is not a rounding error. It is a repricing event.

Mitigation as alpha

In this environment, the operators who will outperform are those who treat insurance cost reduction as a core competency rather than an administrative function. The levers are specific: wind mitigation certifications (new roofing, impact-resistant glazing, hurricane shutters) can reduce premiums by 15–30%. Higher deductibles — moving from 2% to 5% of insured value on named-storm coverage — can reduce premiums by another 10–20%, though this trades premium savings for balance-sheet risk.

In Florida commercial real estate, the best capital improvement you can make in 2023 is a roof — not because the old one leaks, but because the insurance savings will repay the investment in three years.

We have budgeted $1.2 million in wind-mitigation capital expenditures across our Florida portfolio for 2023, targeting premium reductions of 20–25% on the next renewal cycle. The underwriting on these expenditures shows payback periods of 2.5–3.5 years — faster than any tenant-improvement investment we have modeled in the last decade. When insurance is the largest controllable expense in the P&L, mitigation is not maintenance. It is a return-generating capital allocation.
