Premiums have outrun rent growth for five years running. Here’s what that means for the budget model, the reforecast, and the line owners can no longer treat as boilerplate.
For most of the last decade, property insurance was a line item you updated with a modest percentage bump and moved on. That era is over.
Nationally, the Federal Reserve found that real per-unit multifamily insurance costs jumped more than 75% between 2019 and 2024. Moody’s Analytics put the 2024 year-over-year increase alone at 45%. Insurance now accounts for roughly 8% of apartment building operating expenses, nearly double its share five years ago, and the share is still climbing in coastal and storm-exposed markets.
In New York, NYU’s Furman Center found premiums on rent-stabilized buildings have surged 150% since 2019. Commercial Observer reported in April that some New York assets have seen premiums more than double since 2024 alone, prompting a visible pivot among sophisticated owners toward captive insurance structures as a way to claw back control.
This is no longer a renewal surprise. It’s a structural shift in the P&L.
Three forces are stacked on top of each other, and none of them unwind quickly.
Reinsurance capacity has tightened after consecutive years of catastrophe losses. Replacement-cost inflation has pushed insured values up, which inflates premiums before a single rate change hits. And underwriters are tightening terms in ways that rarely show up in the headline number: higher deductibles, wind and named-storm carve-outs, coinsurance requirements, and stricter loss-history reviews. A flat-rate renewal can still cost you materially more in exposed dollars.
First American’s analysis traces part of the pressure to climate-driven loss frequency, part to construction cost escalation, and part to capital recalibrating risk across the whole commercial book. Whatever the mix, the net effect at the property level is the same: the line you used to auto-populate is now one of the most volatile items on the schedule.
Insurance doesn’t just show up in the opex column. It moves NOI, and NOI moves value.
InvestingInCRE’s February analysis estimated that properties in the most affected categories could see NOI and value drop 12% from insurance pressure alone, and that owners need roughly 1.3% of additional annual rent growth just to hold NOI flat. With rent growth compressed and concessions still common in several major metros, that math doesn’t pencil by accident. It pencils only if the budget and the strategy catch up.
Lenders are watching the same line. Debt service coverage ratios tighten as insurance climbs, and that shows up in smaller loan proceeds, tighter covenants, and more cautious appraisals. The 2026 maturity wall is unforgiving enough already. Insurance-driven NOI pressure makes it harder to scale.
The response is getting more sophisticated, and fast.
Some owners are forming or joining captives. Commercial Observer highlighted Real Property Captive, a protected-cell captive platform that launched with $8.3 million in committed premiums from midsize multifamily, single-family, student housing, and industrial operators. Formation costs typically run $85,000–$150,000, plus $250,000–$500,000 in regulatory capital, and implementation takes six months to over a year, but for portfolios spending seven or eight figures annually on coverage, the math increasingly works.
Others are rethinking deductibles, bundling coverage across portfolios, accelerating risk engineering spend on roofs and water mitigation, and pricing catastrophe exposure explicitly in underwriting. Almost everyone is tightening the reforecast cadence. Annual budgets that lock insurance assumptions in October don’t survive a January renewal anymore.
Four practical shifts show up across the teams handling this well.
First, treat insurance as a scenario, not a number. Build budgets with a base, a mid, and a storm case. Know which assets swing the portfolio, and model it.
Second, separate premium from program. A 10% premium bump with a doubled deductible is not a 10% problem; it’s a retained-risk decision. Capture it that way in the model.
Third, push reforecasts closer to the renewals. If your quarterly process can’t ingest a February renewal before the March variance review, the variance review is the wrong conversation.
Fourth, keep the portfolio view. Insurance decisions at one property (deductible, sub-limits, named-storm coverage) have implications for risk transfer across the whole book. A budgeting platform that rolls up by owner, by region, or by risk class beats a stack of workbooks every time.
If the answers are vague, the budget model is the bottleneck. That’s the work.
Kardin was built for exactly this kind of moving target. When an insurance quote lands, the right platform lets you reforecast the affected assets, roll the change up to the portfolio, and see the NOI and valuation impact before the conversation with ownership, not after.
