Insurance costs have become the hidden force reshaping where Americans can afford to buy homes. While most homebuyers focus on mortgage rates and home prices, the cost and availability of homeowners insurance is increasingly determining which markets remain viable for buyers and which are becoming financially untenable. In 2026, climate-driven insurance disruption is no longer a future concern — it is actively redirecting migration patterns, suppressing home values in high-risk areas, and creating affordability crises that extend far beyond the mortgage payment.
This guide examines how climate risk is transforming the insurance landscape, which markets are most affected, and what buyers and sellers need to understand about this rapidly evolving reality.
The Scale of the Problem
The average homeowners insurance premium for a new policy reached approximately $1,950 by the end of 2025, representing an 8.5 percent year-over-year increase. That national average, however, masks extreme variation by state and risk profile.
In Florida, the most expensive state for homeowners insurance, average premiums reached $7,136 in 2025 — nearly three times the national average. Louisiana, Oklahoma, Colorado, and Kansas round out the most expensive states, each heavily impacted by hurricanes, tornadoes, hail, wildfires, or combinations of these perils.
The premium increases are not just incremental adjustments. Insurers traditionally planned for 2 to 3 percent annual expense growth, but the escalating frequency and severity of climate-related catastrophes have blown through those assumptions. Wildfire losses in California, hurricane damage in Florida and the Gulf Coast, hailstorm damage across the Great Plains, and flooding events nationwide have collectively driven insurer losses to unsustainable levels.
The result is a market where nearly half of homeowners surveyed say insurance costs weigh heavily on their purchasing decisions, and 49 percent are considering relocating specifically due to climate concerns. Insurance has moved from a routine closing checkbox to a deal-breaking factor in the homebuying process.
Where Insurers Are Leaving
The most alarming trend is not just rising premiums — it is insurers leaving markets entirely, reducing the availability of coverage and pushing homeowners toward expensive last-resort options.
Florida
Florida’s insurance market has been in crisis for several years. Sixteen property insurers operating in the state have gone insolvent, and sixteen more have withdrawn entirely. Major national carriers including Farmers, Progressive, AAA, and AIG have either left the Florida market or dramatically reduced their exposure.
The exodus has pushed hundreds of thousands of Florida homeowners onto Citizens Property Insurance, the state-backed insurer of last resort. Citizens was designed as a temporary safety net, not a permanent market participant, and its rapid growth has created systemic risk for the state’s finances.
There are some encouraging signs in 2026. Legislative reforms enacted in recent years — including tort reform, restrictions on assignment of benefits abuse, and building code improvements — have begun to attract some insurers back to the market. Citizens policyholders are seeing meaningful premium reductions at renewal in spring 2026. However, the structural vulnerability of a state exposed to increasingly powerful hurricanes means that Florida’s insurance market remains fragile.
California
California faces a different but equally severe insurance challenge. Seven of the twelve major carriers have left or reduced their coverage in the state since 2022, including State Farm and Allstate. A total of 34 insurance companies have been identified as part of the California insurance exodus.
The primary driver is wildfire risk. As development has pushed deeper into the wildland-urban interface and climate change has extended fire seasons, insurer losses from California wildfires have reached catastrophic levels. The devastating fires in recent years accelerated carrier departures and left homeowners in fire-prone areas struggling to find any coverage at all.
California’s FAIR Plan — the state’s insurer of last resort — has seen its exposure double in less than two years and recently requested a 35.8 percent rate hike. The FAIR Plan provides basic coverage but is significantly more expensive than standard market policies and offers less comprehensive protection.
Other Affected States
Louisiana continues to face severe insurance market stress following a series of major hurricanes. Colorado’s Front Range hailstorm exposure has driven up premiums and prompted several carriers to restrict coverage. Coastal areas along the Gulf Coast from Texas through the Carolinas face varying degrees of insurance availability challenges.
How Insurance Costs Affect Home Values
The relationship between insurance costs and home values is becoming increasingly direct and measurable. When insurance becomes prohibitively expensive or unavailable, it suppresses buyer demand, which in turn puts downward pressure on home prices.
This dynamic plays out through several mechanisms. Buyers who cannot obtain affordable insurance cannot get a mortgage — lenders require homeowners insurance as a condition of the loan. Even cash buyers face the financial burden of self-insuring a property worth hundreds of thousands of dollars. As the pool of willing and able buyers shrinks in high-risk areas, homes stay on the market longer and sell for less.
Research has begun to quantify this impact. Properties in areas with the highest climate risk and insurance costs are appreciating more slowly than comparable properties in lower-risk areas, and in some cases, values are declining in absolute terms. The concept of a “climate discount” — where homes in high-risk areas trade at a measurable discount to similar homes in lower-risk areas — is emerging in real estate appraisal and analysis.
For homeowners who purchased in high-risk areas before insurance costs escalated, the double impact of rising premiums and declining appreciation represents a significant wealth erosion. Some homeowners find themselves financially trapped — unable to afford the insurance to stay and unable to sell for enough to leave without taking a loss.
The Migration Effect
Insurance costs are becoming a push factor in domestic migration, adding to the traditional pull factors (jobs, lifestyle, affordability) that drive relocation decisions.
Survey data shows that 58 percent of homeowners would avoid moving to Florida and 52 percent would avoid California specifically due to extreme weather risks and the associated insurance challenges. While these states continue to attract residents for other reasons (climate, lifestyle, employment), the insurance burden is reducing net migration and diverting some potential migrants to lower-risk alternatives.
Markets that benefit from this redirection tend to be in regions with lower climate risk profiles — parts of the upper Midwest, the mid-Atlantic, and the interior Northeast. These areas face fewer catastrophic weather events, maintain more stable insurance markets, and are increasingly attractive to buyers who factor total cost of ownership (including insurance) into their location decisions.
What Buyers Must Do in 2026
If you are buying a home in 2026, insurance due diligence should be a front-of-process consideration, not an afterthought at closing. Here is how to protect yourself.
Get Insurance Quotes Before You Make an Offer
Do not wait until you are under contract to discover that insurance for your target property costs $5,000 or $10,000 per year. Request quotes from at least three insurers as soon as you identify a property you are serious about. If coverage is difficult to obtain or prohibitively expensive, that information needs to factor into your offer price — or your decision to walk away.
Research the Property’s Risk Profile
Use publicly available tools to assess a property’s exposure to flooding, wildfire, hurricanes, and other climate risks. FEMA flood maps, state wildfire risk assessments, and third-party risk scoring services like ClimateCheck and First Street Foundation provide property-level risk data that insurance companies are already using to price your premiums.
Understand Flood Insurance Separately
Standard homeowners insurance does not cover flood damage. If your property is in a FEMA-designated flood zone, you will need a separate flood insurance policy through the National Flood Insurance Program (NFIP) or a private flood insurer. NFIP premiums are transitioning to a risk-based pricing model called Risk Rating 2.0, which has significantly increased costs for some properties while reducing them for others.
Even if your property is not in a designated flood zone, consider flood insurance. Approximately 25 percent of flood claims come from properties outside high-risk zones, and a single flooding event can cause tens of thousands of dollars in damage.
Factor Insurance Into Your Affordability Calculation
When calculating whether you can afford a home, include the actual insurance quote in your monthly housing cost — not an estimate, not a national average, but the real number for that specific property. A home that looks affordable based on the mortgage payment alone may become unaffordable when you add $500 or $800 per month in insurance premiums.
Ask About Mitigation Discounts
Many insurers offer premium discounts for homes with features that reduce risk: impact-resistant roofing, hurricane shutters, fire-resistant landscaping, updated electrical and plumbing, and monitored security systems. If you are buying a home that lacks these features, factor the cost of adding them into your renovation budget and calculate the premium savings they will generate.
What Sellers Should Know
If you are selling in a high-risk area, insurance is increasingly a factor that buyers will raise during the transaction. Be prepared with information about your current insurance carrier, premium amount, claims history, and any mitigation features your home has. A property with an established insurance policy and a clean claims history is more attractive than one where the buyer faces an uncertain insurance search.
Consider investing in risk mitigation before listing. A new impact-rated roof, defensible space landscaping in wildfire areas, or flood prevention measures can make your home more insurable and more attractive to buyers who are factoring insurance into their decision.
The Bigger Picture
Climate risk and insurance disruption are not temporary market fluctuations — they represent a structural shift in how real estate is valued and where people choose to live. The markets that thrive in the coming decades will be those that combine economic opportunity with manageable climate risk and stable insurance availability.
For individual buyers, this means expanding your evaluation criteria beyond the traditional factors of price, location, and schools to include climate resilience, insurance availability, and long-term risk trajectory. A home that is affordable today but faces rising insurance costs and declining value due to climate risk may be a poor long-term investment, even if it checks every other box.
The insurance market is sending a price signal that the real estate market is still catching up to. Buyers who pay attention to that signal — and incorporate it into their decision-making — will be better positioned than those who treat insurance as an afterthought.
