Why Multifamily Insurance Costs Keep Rising, and What It Means for Investors

Read Time: 7 min

Ask any multifamily owner what changed the most about their operating budget over the past few years and insurance is near the top of nearly every list. Premiums on apartment communities have moved up at a pace that outstrips rent growth in most markets, which means insurance has gone from a modest line item to one that genuinely affects deal economics. For passive investors evaluating a syndication, understanding why this is happening and how a sponsor should respond to it is worth as much attention as the cap rate or the rent growth assumptions in the underwriting.

What's Actually Driving the Increases

Reinsurance Markets Are Repricing Risk

Property insurers do not hold all of their risk themselves. They pass a portion of it to reinsurers, and reinsurance pricing has moved up as the reinsurance industry recalculates the cost of catastrophic events, from hurricanes to severe convective storms in parts of the country that historically saw less of this activity. When reinsurance gets more expensive, that cost flows down to the primary insurer and eventually to the property owner's premium.

Replacement Costs Have Moved Up

Insurers price a policy in part based on what it would cost to rebuild the property if it were destroyed, and construction costs for materials and labor have climbed. A policy written a few years ago may no longer reflect what it would actually cost to replace the building today, and insurers have been adjusting coverage amounts and premiums accordingly as replacement cost estimates catch up to current conditions.

Fewer Carriers Are Willing to Write Multifamily Risk

Some insurers have pulled back from writing coverage on older buildings, certain construction types, or properties in specific geographies altogether, which reduces competition among the carriers still willing to quote a policy. Less competition in a given market or property type tends to push pricing higher regardless of what is happening with any individual property's claims history.

How This Shows Up in Underwriting

A sponsor underwriting a new acquisition today has to model an insurance line that may look meaningfully different from what the seller was paying, particularly if the seller has held the property for several years and never faced a renewal at current market pricing. Deals that assume the seller's trailing insurance expense will carry forward unchanged are a common source of underwriting error, and it is one of the first things a careful passive investor should ask about when reviewing a deal's operating assumptions.

Underwriting Question	Why It Matters
Is the insurance line based on a bound quote or a trailing expense?	A trailing expense from the seller can understate what the buyer will actually pay at closing
Does the projection include an annual escalation for insurance?	Flat-lining insurance costs across a five-year hold has been a common and costly underwriting mistake
Has the sponsor obtained an actual quote before closing?	A bound or firm quote removes guesswork that a rough estimate cannot
How does the property's construction type and age affect insurability?	Older buildings and certain construction types can face higher premiums or narrower carrier options

What Sponsors Can Do About It

Experienced operators respond to a harder insurance market in a few consistent ways: shopping the policy across multiple carriers and brokers rather than renewing on autopilot, investing in property-level risk mitigation such as updated roofing, plumbing, or fire suppression systems that can improve insurability, and building a realistic annual escalation into the underwriting rather than assuming costs stay flat. None of these fully offsets a market-wide repricing of risk, but together they can meaningfully narrow the gap between a naive projection and what a property will actually cost to insure.

How Red Brick Equity Approaches Insurance in Underwriting

We build a realistic, escalating insurance line into every deal's underwriting rather than assuming the prior owner's expense carries forward unchanged, and we shop coverage across multiple carriers before closing rather than defaulting to whatever policy the seller happened to have in place. Given how much insurance costs have moved in recent years, treating this line item as a fixed, minor expense is one of the more common ways a deal's actual performance can fall short of its projections, and it is a discipline we apply consistently across our portfolio.

How Rising Insurance Costs Can Affect Distributions

Insurance is an operating expense that sits above the net operating income line, which means a premium increase that was not built into the original underwriting reduces cash flow directly, dollar for dollar, before it ever reaches investors as a distribution. On a well-underwritten deal with a realistic insurance escalation baked in from the start, a market-wide premium increase is already accounted for and should not meaningfully change what investors receive. On a deal where the sponsor assumed the seller's old, below-market premium would carry forward unchanged, the gap between the original projection and the actual renewal quote comes directly out of distributable cash flow, which is exactly why this line item deserves attention before you commit capital, not after the first disappointing distribution.

Property-Level Choices That Affect Insurability

Beyond the macro trends driving the broader market, decisions made at the property level meaningfully affect what a specific building can be insured for. Updated electrical and plumbing systems, modern fire suppression and alarm systems, and a documented history of proactive maintenance all give an insurer more confidence in the risk they are underwriting, which can translate into more competitive quotes even in a difficult broader market. A sponsor's renovation plan for a value-add property should account for how specific capital improvements affect insurability, not just how they affect rent potential, since the two are more connected than they might first appear.

What This Means for Passive Investors Evaluating a Deal

When you review a syndication's offering documents, ask specifically how the insurance line was derived and whether it escalates over the hold period. A sponsor who can answer that question with specifics, rather than a vague reference to "current market rates," is generally showing a more disciplined underwriting process. Rising insurance costs are a real and durable feature of the current environment, not a temporary blip, and deals underwritten with that reality in mind tend to hold up better than ones that were not.

Why This Isn't a Reason to Delay Investing

It can be tempting to read a trend like this and conclude the right move is to wait for insurance markets to settle before committing capital. That framing misses the more useful question. The relevant issue is not whether insurance costs are elevated across the market generally, since every owner and every sponsor is operating under the same conditions, but whether a specific deal's underwriting has already accounted for that reality at today's actual cost, not a stale or hopeful estimate. A deal underwritten conservatively against current insurance pricing can still make sense even in a hard market. A deal that ignores the trend is a poor bet regardless of when you invest.

Frequently Asked Questions

Are multifamily insurance costs rising everywhere, or just in certain regions?

The pressure is broad, but it is more acute in markets with higher exposure to catastrophic weather events. Even in lower-risk regions, however, reinsurance repricing and rising replacement costs have pushed premiums up across most of the country.

How much can insurance costs affect a syndication's returns?

It varies by deal, but insurance is one of several operating expense lines that, if underestimated at underwriting, can compress the actual cash flow and returns an investor ultimately receives relative to the original projection. This is exactly why the underwriting assumptions behind this line item are worth scrutinizing.

Can a property owner do anything to lower their insurance premium?

Yes, to a degree. Physical improvements such as updated roofing, plumbing, and fire safety systems, along with shopping the policy across multiple carriers, can meaningfully affect the quote a property receives, even though they cannot fully offset a broader market-wide repricing.

Should I ask a sponsor about their insurance assumptions before investing?

Yes. Asking whether the insurance line is based on a bound quote and whether it escalates over the hold period is a straightforward, specific question that tells you a lot about how carefully a deal was underwritten.

Is rising insurance a reason to avoid multifamily investing altogether?

Not on its own. It is a reason to favor sponsors who underwrite this line item realistically rather than avoiding the asset class, since every real estate owner, in every strategy, is facing the same market conditions.
