Something has quietly shifted in the American housing market over the past few years, and it’s not just interest rates or pandemic corrections. In certain corners of the country, home values are eroding for a reason that buyers didn’t used to factor into their calculations: climate risk. Rising flood exposure, hurricane frequency, wildfire threat, and the insurance chaos that follows all of these events are now directly moving prices in specific communities.
The data is increasingly clear and hard to ignore. Climate change-driven disaster risks are having a measurable impact on property insurance rates and home values. What’s more telling is where that impact shows up most sharply. Below are five real zip code areas where the numbers are falling fast, and the reasons why.
Cape Coral, FL (33904 / 33909) – The Canal City That Insurance Built and Is Now Helping Unwind
Cape Coral seemed unstoppable just a few years ago. Home values in Cape Coral soared by more than roughly 60% from 2020 to 2022, creating an unsustainable price level that’s now correcting. The correction is real and measurable: the median home value for the Cape Coral-Fort Myers metro area declined by 10% over the past year, as of October 2025.
The flood risk picture here is striking. Nearly 89% of all properties in Cape Coral are at risk of severe flooding over the next 30 years, and flood risk is increasing faster than the national average. Add to that the fact that every single property in Cape Coral carries extreme risk of a severe wind event over the next 30 years, with the city most exposed to hurricanes, and the market dynamics become less surprising. An analysis showed home prices in Cape Coral-Fort Myers have dropped by 11% over the last couple of years, with more than half of homes experiencing price cuts.
Fort Myers Beach, FL (33931) – Still Stalled After Hurricane Ian
Fort Myers Beach and the surrounding zip codes in Lee County have faced a prolonged recovery that shows no clean end point. According to Realtor.com data, listing prices in Lee County were still about 7.5% lower than pre-Ian levels as of May 2025 – nearly three years after the storm hit. That kind of sustained suppression is unusual, and it signals something structural rather than temporary.
Ground-level properties in flood zones faced the toughest economics: higher insurance premiums, major structural repairs, and in some cases special assessments for condo owners. Cape Coral also has the highest percentage of homeowners underwater in the country, with nearly 8% owing more on their mortgages than their homes are worth. The broader Lee County market remains gridlocked, and homes that once attracted short-term rental investors are now sitting idle at deep discounts.
Sarasota, FL (34231 / 34242) – From Peak Boom to Stalled Retreat
Sarasota was one of the most sought-after markets in Florida during the pandemic migration wave. That has changed considerably. Real estate is down roughly 15 to 20% from its peak in the Sarasota area and is stalled out in the Fort Myers region as a holdover from Hurricane Ian. Insurance costs in this corridor are among the most severe in the country.
A homeowner in Lakewood Ranch or Sarasota who was paying $2,400 per year in homeowners insurance in 2019 may now be paying $6,000 to $8,000 or more. That’s a line item that completely changes affordability math for buyers. Climate issues of the past four to five years have also slowed the migration to Florida from the Northeast, cutting off a key source of demand that had propped up prices during the peak years.
New Orleans Metro, LA (70114 / 70117) – A Market That Insurance Has Nearly Abandoned
Louisiana’s climate risk story is arguably more severe than Florida’s in terms of the insurance collapse alone. At least a dozen home insurers left Louisiana following four major hurricanes endured by the state in 2020 and 2021. When that many carriers exit a single market in such a short window, the effect on buyers and property values is predictable and lasting.
In 2024, the average insurance premium in Louisiana hit $10,964 – the second-highest in the nation after Florida. That’s more than three times the national average, and for many zip codes in greater New Orleans, it tips marginal properties into effectively unfinanceable territory. In Louisiana, somewhere between 30 and 40% of mortgage loan applications fail specifically because of high home insurance costs – a figure that reflects just how thoroughly climate risk has infiltrated the transaction itself.
Los Angeles Wildfire Fringe, CA (91001 / 91024) – Inventory Surge, Value Stagnation
The 2025 Los Angeles wildfires put wildfire-adjacent zip codes across the San Gabriel Valley and foothill communities under a harsh spotlight. In the immediate aftermath, new listings within 5 miles of the fire perimeters surged nearly 194% in January 2025 compared with December 2024 – more than double the increase seen in areas further from the fires – and remained 45% above pre-fire levels by November 2025. A flood of listings pushing into the same market without equivalent buyer demand does one thing to prices.
Following the 2025 wildfires that plagued Los Angeles, roughly 4 in 10 insurance policyholders experienced insurability issues, including huge premium increases and dropped coverage. The risk data had actually flagged this. According to First Street data available on Zillow listings, 94% of properties that burned in the 2025 fires were labeled as having severe or extreme wildfire risk – yet many buyers had never seen those scores before closing. More than one in five borrowers within the 2025 Eaton and Palisades wildfire zones fell behind on their mortgage payments the month following the fires.
What’s Actually Driving the Decline Across All Five Areas
The price drops in these zip codes aren’t happening in a vacuum. They share a common mechanism: insurance costs rising to the point where they change who can afford to buy, and on what terms. Research found that the rise in reinsurance prices for homes in the riskiest 10% of zip codes led to declines in home values of $43,900 from 2018 to 2024 relative to what they otherwise would have been. That’s not a rounding error in a real estate portfolio.
Research shows that rising premiums have resulted in a major repricing of climate-exposed housing assets, causing a relative home price decline of 11% among zip codes that are highly exposed to increasing risk and in the top decile of catastrophe exposure. Meanwhile, the broader mortgage market is adjusting too. In June 2024, Freddie Mac released rules requiring mortgage issuers to use full flood risk premiums in calculating housing expense-to-income and debt payment-to-income ratios for homes within special flood hazard areas – a structural change that tightens access to credit for buyers in high-risk zones and further constrains demand.
The Transparency Gap That Makes This Worse
One of the more troubling dimensions of this trend is how little buyers know before they close. Just over a year after adding climate risk scores, Zillow removed them from more than 1 million listings after real estate agents complained that the information was causing them to lose sales – even though Zillow had noted that more than 80% of buyers consider climate risks when purchasing a home. Pulling back that information doesn’t make the risk go away.
Estimates suggest that from 2013 to 2024, roughly $31 billion of total residential real estate value in the U.S. may have been lost due to flood risk alone. Based on analysis of home values, homes in at-risk communities could face a value correction of between $1.7 and $2.7 trillion if property markets reprice to fully reflect the threats posed by increasingly intense storms, subsidence, sea level rise, and wildfires. That’s the full scale of what markets are still in the process of pricing in – and in these five zip code clusters, that process is already well underway.
