Property Insurance Is the Operating Expense That Reprices Faster Than Rent

Property insurance in CRE is the operating expense that reprices faster than rent. Rent is contractual. It moves once a year at renewal, bounded by the lease, the market, and the tenant's willingness to pay. Property insurance answers to none of that. It reprices annually against replacement cost, catastrophe models, and reinsurance pricing set half a world away. In the hard market of 2020 to 2024, that asymmetry turned a routine line item into the fastest-moving number on the operating statement, and it compressed income in buildings where rent barely moved.

Key Takeaways

Property insurance reprices every 12 months at policy renewal against replacement cost and catastrophe risk, while rent reprices slowly and only inside the bounds of existing leases.
Federal Reserve research found real multifamily insurance cost rose from about $39 per unit per month in 2019 to $68 in 2024, an increase of more than 75 percent, while national apartment rent grew roughly 1 percent in 2024.
The Federal Reserve Bank of Minneapolis reported multifamily insurance premiums rising at an average annual rate near 45 percent in 2024, a single-year move rent cannot match.
Insurance reprices in both directions: Marsh reported US commercial property rates falling 10 percent in the first quarter of 2026, the underwriting must survive the next hard market, not the current soft one.
An expense that moves faster than income belongs in your underwriting as a variable, not a fixed line trended at inflation.

Why does property insurance reprice faster than rent?

Property insurance reprices faster than rent because the two prices answer to different clocks and different inputs. Rent is set by contract and moves at renewal, constrained by the lease term and local market. Insurance is repriced every year against replacement cost, loss history, and reinsurance capacity, none of which the operator controls.

A lease is a brake on rent. It fixes the number for the term, staggers renewals across a rent roll, and caps how fast income can climb even in a strong market. Insurance carries no such brake. At every renewal the carrier reunderwrites the risk from scratch, marks the building to current replacement cost, and passes through whatever reinsurance now costs. When Gulf Coast hurricanes and wildfire seasons pushed reinsurance rates up, that increase arrived in the operator's next renewal in full, not amortized over a lease term.

Attribute	Rent	Property insurance
Reprice frequency	At lease renewal, staggered	Annually, whole policy at once
Basis	Market and contract	Replacement cost, catastrophe models, reinsurance
Direction constraint	Bounded by lease and market	Unbounded up or down
Operator leverage	Negotiable at renewal	Price-taker
Speed of pass-through	Slow, lease by lease	Immediate, portfolio-wide

The result is structural. Rent is a slow, bounded, staggered variable. Insurance is a fast, unbounded, synchronized one. In a hard market they move in opposite proportions, and the operating statement absorbs the gap.

How much did property insurance costs actually rise?

Property insurance costs rose faster than almost any other line on the operating statement during the last hard market. Federal Reserve researchers found real multifamily insurance cost climbed from about $39 per unit per month in 2019 to $68 in 2024, an increase of more than 75 percent over five years while general inflation and rent growth ran far below that.

The concentration is worse than the average suggests. In the September 2025 Federal Reserve note by Samuel Hughes and Raven Molloy, 29 of the 94 metropolitan areas studied recorded more than 100 percent real growth in property insurance cost between 2019 and 2024, led by coastal and catastrophe-exposed markets in Florida, Texas, Louisiana, and the Carolinas. The Federal Reserve Bank of Minneapolis reported multifamily premiums rising at an average annual rate near 45 percent in 2024 alone.

Set that against income. National apartment rent grew roughly 1 percent in 2024 by Fannie Mae's multifamily commentary. A line item moving 45 percent in a year sits inside a revenue line moving 1 percent. No trending assumption reconciles those two numbers, which is why insurance broke so many pro formas written before 2022. Understanding where underwriting models go wrong on net operating income starts with the expense line that moves fastest.

What does insurance repricing do to net operating income?

Insurance repricing compresses net operating income directly, because it hits the expense side faster than the rent side can respond. When an expense line rises by more dollars than a year of rent growth adds, the property loses income even in a market that looks healthy on the revenue line. The operating expense ratio climbs, and value falls with it.

Work a 200-unit property. Average rent is $1,500 per unit per month, so gross potential rent is $3,600,000 a year. Apply a 1 percent rent increase, near the 2024 national figure, and revenue gains $36,000. Now the insurance line. Using the Federal Reserve per-unit path, take insurance from roughly $566 per unit in 2023 to $821 in 2024, a 45 percent move consistent with the Minneapolis Fed reading. That is a $255 per-unit increase, or $51,000 across 200 units.

Line	Amount
Gross potential rent (200 units, $1,500/mo)	$3,600,000
Rent gain at 1 percent	+$36,000
Insurance, 2023 (200 x $566)	$113,200
Insurance, 2024 (200 x $821)	$164,200
Insurance increase	-$51,000
Net effect on NOI before other lines	-$15,000

In one cycle a single expense line rose by $51,000 while the entire year of rent growth added $36,000. The building lost $15,000 of net operating income before any other cost moved. At a 6 percent cap rate, that $15,000 swing is $250,000 of value, erased by a line that was 4 or 5 percent of the operating statement. The magnitude of the expense is not the point. Its speed is.

Is the current soft market a reason to relax underwriting?

No. The soft market is the same mechanism running in reverse, and it is temporary. Insurance reprices in both directions on the same annual clock, so today's rate cuts are not a floor. Marsh's Global Insurance Market Index reported global commercial property rates down 9 percent in the first quarter of 2026, with US property off 10 percent, the seventh consecutive quarter of decline.

The Council of Insurance Agents and Brokers recorded commercial property premiums falling in the fourth quarter of 2025 as capacity returned and reinsurance costs eased. That relief is real, and it is exactly why underwriting should not anchor to it. The property that penciled in 2019 broke in 2023 because insurance reunderwrites every year and the model treated it as fixed. A pro forma built on 2026 soft-market pricing will break on the next catastrophe cycle the same way.

The discipline is to read the insurance line as a variable that moves with catastrophe exposure and reinsurance, not a fixed cost trended at CPI. When you pull a seller's trailing twelve months, isolate insurance and ask what renewal, not what the last policy, will cost. Reading what the T-12 line items reveal about the seller's story is where a stale insurance number gets caught before it becomes your problem. Underwrite the renewal, not the trailing figure, and size replacement reserves and contingency against a repricing you do not control.

Frequently Asked Questions

Why does property insurance reprice faster than rent in CRE?

Rent is fixed by lease contracts and moves only at staggered renewals, bounded by the market. Property insurance is reunderwritten every year against replacement cost, loss history, and reinsurance pricing, none of which the operator controls, so it moves faster and in larger single-year steps.

How much did commercial property insurance rise in the last hard market?

Federal Reserve research found real multifamily insurance cost rose more than 75 percent from 2019 to 2024, and the Federal Reserve Bank of Minneapolis reported an average annual increase near 45 percent in 2024. Coastal and catastrophe-exposed metros saw more than 100 percent growth over five years.

Does the 2026 soft market mean insurance risk is over?

No. Marsh reported US commercial property rates down 10 percent in early 2026, but the same annual repricing that cuts rates now raised them sharply from 2020 to 2024. Rates move both ways on a yearly clock, so underwriting should assume the next hard market, not the current relief.

How should I underwrite property insurance in a pro forma?

Treat insurance as a variable tied to catastrophe exposure and reinsurance, not a fixed line trended at inflation. Underwrite the next renewal rather than the trailing policy, and carry contingency for a repricing you cannot control.

Conclusion

Property insurance in CRE is the operating expense that reprices faster than rent because it answers to a different clock. Rent is bounded by leases and moves once a year in small steps. Insurance reunderwrites the whole risk every twelve months against replacement cost and reinsurance an operator cannot negotiate. That asymmetry compressed net operating income across the last hard market and will do it again when the current soft market turns. Underwrite the insurance line as the fast-moving variable it is, size the renewal not the trailing number, and the fastest line on your operating statement stops writing the surprise into your returns.
