For years, property insurance was a line item investors barely thought about, a predictable, modest cost baked into the pro forma without much scrutiny. That’s no longer true in a growing number of markets, where premiums have risen sharply enough to meaningfully change a deal’s actual return.
Why Insurance Costs Have Climbed
A combination of more frequent severe weather events, rising construction and repair costs, and insurers pulling back from the highest-risk markets entirely has pushed premiums up meaningfully faster than rents in many parts of the country. In some coastal and wildfire-exposed markets, insurers have stopped writing new policies altogether, leaving investors dependent on state-backed insurers of last resort, often at a significantly higher cost.
Where the Impact Is Concentrated
- Coastal markets exposed to hurricane risk, where wind and flood coverage have both climbed
- Wildfire-prone regions, where some insurers have exited entirely rather than continue underwriting the risk
- Older properties, which often cost more to insure due to outdated electrical, plumbing, and roofing systems
- Markets with a history of frequent claims, where insurers price in loss history at the regional level, not just the individual property
How Rising Premiums Actually Affect Returns
Insurance is a fixed operating expense that doesn’t scale down when a deal underperforms, and a meaningful premium increase can convert a marginal deal into a losing one without a single change to rents or occupancy. Investors who underwrote a property years ago at a much lower premium can find their actual cash flow considerably thinner than projected once a policy renews at current rates.
How to Underwrite for This Going Forward
- Get an actual current quote before closing, not a prior owner’s premium or a generic regional estimate
- Model a meaningful premium increase at renewal, rather than assuming today’s rate holds for the life of the hold period
- Factor in property condition specifically, since roof age, electrical systems, and prior claims history all affect pricing directly
- Understand the state-backed insurer of last resort option in high-risk markets, including its cost and coverage limitations, before assuming private coverage will always be available
Key Takeaways
- Property insurance has shifted from a predictable minor cost to a major underwriting variable in many markets
- Coastal, wildfire-prone, and older properties are seeing the steepest premium increases
- Rising premiums can turn a marginal deal unprofitable without any change to rents or occupancy
- Getting a current quote and modeling renewal increases are now essential steps, not optional ones
Final Thoughts
Insurance risk is exactly the kind of underwriting detail that separates investors who get surprised by a renewal notice from those who saw it coming and planned for it.
It’s also a meaningful part of why ALM evaluates insurance costs and carrier relationships as part of the underwriting for every Mansion Builder project, well before construction begins, not after a policy renewal delivers a surprise.
