For most of the past several years, the conversation around housing affordability in America has revolved around two familiar culprits: home prices and mortgage rates. When rates climbed sharply and home values stayed stubbornly high, buyers felt the squeeze in ways that were easy to measure and simple to explain. But in 2026, a third variable has entered the equation with enough force to change where people can afford to live, which properties lenders will finance, and potentially what homes are actually worth. That variable is homeowners insurance, and according to the kind of deep, research-driven analysis that Abraham Sanieoff has long championed in real estate, ignoring it is one of the most costly mistakes a buyer, seller, or investor can make right now.

This summer, as buyers across the country navigate an already complicated housing market, the cost of insuring a property is no longer a line item to review at closing. It is a foundational part of the affordability calculation, and in many cases it is the number that breaks a deal, shrinks a buyer pool, or quietly erodes a property's long-term value. Understanding this shift is essential for anyone thinking seriously about real estate in 2026.

The Numbers That Are Quietly Redefining What Affordable Means

The scale of the insurance problem in residential real estate is larger than most buyers realize until they are already deep into a transaction. A July 2026 analysis by Realtor.com found that nearly 23.1% of U.S. homes, representing approximately $11.2 trillion in residential real estate, face severe or extreme wind, flood, or wildfire risk. That is not a niche problem confined to a handful of coastal towns or fire-prone mountain communities. It is a structural feature of a significant share of the American housing stock.

At the same time, the cost of insuring those properties has been rising sharply. Research summarized by the National Bureau of Economic Research found that average nominal homeowners insurance premiums increased 33% between 2020 and 2023. That kind of increase does not simply raise monthly housing costs in isolation. The NBER research estimates that insurance-market shocks reduced 2023 home values by an average of roughly $8,400, with stronger effects in markets where climate risk is growing. A 2026 GAO analysis added geographic texture to the picture, finding substantially greater premium increases in some disaster-prone locations, including increases of 25% or more in southern coastal areas during the period it examined.

The National Association of Realtors captured the broader affordability impact in a particularly striking way. When elevated homeowners insurance costs were incorporated into its March 2026 Housing Affordability Index, the index fell from 113.7 to 109.0, a roughly four-point deterioration. That may sound like an abstract figure, but it represents a measurable reduction in the share of households that can comfortably afford median-priced homes in their markets. It is the kind of number that should change how buyers, agents, and investors approach every transaction.

How Abraham Sanieoff Thinks About the True Cost of Homeownership

One of the core ideas that runs through Abraham Sanieoff's approach to real estate is that the sticker price of a home is never the whole story. The traditional affordability calculation that buyers have used for decades looks something like this: purchase price, plus the monthly cost of a mortgage at a given interest rate, plus property taxes. Add those up, compare them to household income, and you have a rough sense of what is affordable.

That model is no longer adequate. The calculation that reflects the actual cost of owning a home in 2026 looks considerably different. It includes the mortgage payment, property taxes, homeowners insurance, any separate flood or fire coverage required for the property's specific risk profile, HOA fees where applicable, and the expected cost of maintenance or risk-mitigation work that may be necessary to keep coverage in force or prevent losses. When you add all of those together, what you get is something more honest: the true monthly cost of ownership.

This reframing leads to one of the most useful concepts for navigating today's market, which is the idea of an insurance-adjusted home price. Consider a buyer comparing two properties. The first is listed at $450,000 in a lower-risk area with insurance that is readily available and reasonably priced. The second is listed at $425,000 but sits in a flood zone or wildfire corridor, carries annual insurance premiums that are thousands of dollars higher, and may require separate specialized coverage on top of a standard policy. Once the true monthly costs are calculated, the cheaper property may not be cheaper at all. The $25,000 difference in purchase price can disappear quickly when insurance costs are annualized over a standard mortgage term.

This is not a theoretical exercise. It is a practical reality that buyers are encountering this summer in markets across the country, from Florida's Gulf Coast to the foothills of California to the rapidly developing areas of the Texas coast.

The Questions Every Buyer Should Ask Before Making an Offer

One of the most actionable insights that flows from taking insurance seriously as part of affordability is a shift in timing. Buyers have traditionally thought about insurance near the end of a transaction, often during the final stages of the due diligence period. In 2026, there are strong reasons to investigate insurance during the initial affordability analysis, before a buyer falls in love with a property and before emotional investment makes it harder to walk away.

There are several specific questions worth building into that early research process:

• Is the property located in a designated flood zone, wildfire risk zone, wind corridor, or other recognized hazard area?
• What does the current owner pay for homeowners insurance, and what does that policy actually cover?
• Is the seller's current premium transferable, or will a new buyer be underwritten at current market rates, which could be significantly higher?
• What deductibles apply, particularly for wind or hail damage in storm-prone areas, where deductibles are sometimes calculated as a percentage of the home's insured value rather than a flat dollar amount?
• Does the property require separate flood insurance, wildfire coverage, or other specialized policies beyond a standard homeowners policy?
• Have major insurers recently stopped writing new policies in this area, or have any carriers non-renewed existing policies at scale?

That last question is particularly important. When insurers pull back from a market, the buyers who remain have fewer options, often at higher prices, sometimes through state-backed insurers of last resort that carry their own limitations. Mortgage lenders generally require adequate insurance as a condition of financing, which means a property that cannot be reasonably insured can become a property that cannot be financed. The implications for a buyer already stretched thin by today's prices and rates are significant.

The most important step in this process is obtaining an actual insurance quote for the specific property before submitting an offer, rather than assuming the seller's premium will be representative of what a new buyer will pay. In many markets right now, that assumption can be off by a wide margin.

What This Means for Sellers, Investors, and the Long-Term Trajectory of Home Values

The insurance dynamic is not only a buyer's problem. It is reshaping the incentives and strategies of sellers and investors as well, and understanding those shifts is part of how Abraham Sanieoff encourages a more complete view of where the housing market is heading.

For sellers, particularly those in higher-risk areas, the ability to document resilience improvements is increasingly valuable. A newer roof built to current wind-resistance standards, defensible space that satisfies wildfire mitigation requirements, drainage improvements that reduce flood exposure, or storm shutters and impact-resistant windows are no longer simply aesthetic upgrades or maintenance items. They are features that can affect whether a buyer can obtain insurance at a reasonable cost, which in turn affects the size of the buyer pool and the price that can be achieved. Sellers who proactively gather documentation of these improvements and understand how their current insurer views them are better positioned to attract serious buyers and support their asking price.

For real estate investors, the implications are broader and in some ways more disruptive. Investment models that treat insurance as a predictable expense increasing at ordinary inflation rates are increasingly disconnected from market reality. The 33% premium increase between 2020 and 2023 documented by NBER research is not a one-time adjustment. Insurance volatility can affect operating expenses, compression of cap rates, cash flow projections, and ultimately the valuations that buyers of investment properties are willing to support. Research published in 2026 has also identified insurance as a growing challenge for affordable housing development and operations, meaning the ripple effects extend beyond market-rate housing into the broader ecosystem of residential real estate.

The mechanism connecting insurance to home values is worth understanding clearly. Higher risk exposure drives higher premiums. Higher premiums raise the true monthly cost of ownership. A higher ownership cost qualifies a smaller pool of buyers for any given property. A smaller qualified buyer pool reduces demand. Reduced demand, all else equal, creates downward pressure on prices. This chain reaction does not play out uniformly, and it does not mean that high-risk properties automatically lose value. Location desirability, housing shortages, strong local economies, and meaningful price discounts can offset the insurance drag. In fact, the Realtor.com 2026 analysis found that buyers are continuing to pursue some high-risk properties specifically because the purchase-price discount is compelling enough to make the risk seem acceptable.

That tension is one of the defining features of the current market. Many buyers understand intellectually that some homes carry elevated risk, but affordability pressures are powerful enough that they accept the tradeoff anyway. The danger is accepting that tradeoff without fully understanding its scope, including the possibility that insurance costs will continue rising, that coverage availability may narrow further, or that property values in high-risk markets could face greater pressure over time as those dynamics compound.

What Abraham Sanieoff consistently emphasizes is that real estate decisions made with incomplete information are not simply less optimal. They can be genuinely costly in ways that take years to become visible. The buyer who purchases a seemingly discounted property in a high-risk area without fully modeling the insurance costs, the potential for future premium increases, and the financing implications is not getting a deal. They may be absorbing a risk that the market has already begun to price in.

The big story in real estate this summer is not simply whether home prices will soften or whether mortgage rates will ease. The bigger and more durable story is that the definition of affordable housing is changing. A property is only affordable if it can be insured at a cost the buyer can sustain, financed by a lender willing to accept the risk profile, and maintained over time without insurance-related surprises eroding the financial case for ownership. Buyers, sellers, and investors who build that full picture into their decision-making are not just being cautious. They are being strategic in a market that increasingly rewards that kind of thoroughness.
