Frequently Asked Questions

Flood insurance landscape?

NFIP (FEMA): up to $250k structure / $100k contents. Risk Rating 2.0 in effect, premium tied to actual flood risk. Private flood: higher limits ($500k–5M), often cheaper than NFIP for low-risk, more expensive for high-risk Special Flood Hazard Areas (SFHA). Required by lender for SFHA properties. Annual cost: low risk $400–800, moderate $700–2k, high SFHA $1.5k–6k+. Elevation certificate: critical document, $300–600 cost, can save 30–60% premium. Mitigation: elevation, dry/wet floodproofing, openings reduce premium significantly.

How is this insurance cost determined?

Property and liability insurance pricing depends on construction class, occupancy class, sprinkler/alarm, location (CAT exposure: hurricane, earthquake, flood, wildfire), claims history, deductibles, and policy limits. Hard market 2022–2025: rates +20–60%, capacity tighter, deductibles higher. Soft market typical 2010–2019: stable to declining. Underwrite for cycle.

Coverage adequacy?

Property: replacement cost vs ACV, coinsurance penalty if under-insured (80–100% requirement). Business interruption: 12–24 months typical, period of restoration triggers. General liability: $1–2M/$2–4M, umbrella to $5–25M depending on occupancy. Pollution legal liability: critical for environmental-risk assets. Builders risk for construction. Match coverage to actual exposure.

Deductible strategy?

Higher deductibles save 5–25% on premium but require risk capital. Wind/hail named storm deductibles: 2–10% of TIV in CAT zones. All-other-perils: $5–25k typical. Self-insured retention (SIR) for sophisticated operators: $50k–500k. Captive insurance: $1M+ minimum, complex but effective for portfolios. Match deductible to financial strength and risk tolerance.
