A suburban house surrounded by floodwaters after heavy rain, showing impact of natural disaster and how climate change could trigger home foreclosures.

Imagine losing your home not because you lost your job or couldn’t make payments, but because a hurricane damaged your property and your insurance didn’t cover the repairs. Unfortunately, this scenario is becoming increasingly common—and it’s about to get much worse.

The Alarming Numbers


A groundbreaking study from First Street Research has uncovered a troubling trend that should concern every homeowner in America. According to their analysis, climate-related foreclosures could surge by 380% over the next decade. Even more shocking? By 2035, extreme weather events could account for nearly one-third of all foreclosures nationwide, compared to just 7% today.


This isn’t just about losing homes—it’s about losing the foundation of American wealth. For most families, their home represents their largest financial asset, making this crisis particularly devastating for middle and lower-income households.


The Financial Fallout


The ripple effects extend far beyond individual homeowners. Lenders are facing a tsunami of losses they never saw coming:


  • $1.2 billion in losses projected for 2025 alone
  • $5.4 billion annually by 2035
  • Billions more in indirect costs as the crisis deepens

Jeremy Porter, head of climate implications at First Street, calls these the “hidden risks” of climate change—costs that lenders simply aren’t factoring into their decision-making process.


The Insurance Gap Crisis


Here’s where things get really concerning: the very insurance meant to protect us is failing. As premiums skyrocket and insurers abandon high-risk markets, homeowners are finding themselves dangerously exposed.


The numbers tell the story:


  • For every 1% increase in insurance costs, foreclosure rates jump by roughly 1%
  • Millions of at-risk properties lack adequate flood insurance
  • Properties outside FEMA flood zones see 52% higher foreclosure rates after flood events

Who’s Most at Risk?


The communities facing the greatest danger share several characteristics:


  • High population density
  • Expensive real estate markets
  • Large numbers of underinsured homeowners
  • Coastal locations vulnerable to storms and flooding

Florida leads the pack, with 8 of the top 10 highest-risk counties in the nation. Duval County alone could see $60 million in credit losses from 900 foreclosures in a single severe weather year.


But this isn’t just a coastal problem. Louisiana, California, and northeastern states are also in the crosshairs, while inland areas face growing threats from extreme rainfall and river flooding.


The Flood Zone Blind Spot


One of the most alarming findings involves flood risk mapping. While FEMA identifies about 8 million at-risk properties in its flood zones, First Street estimates the real number is closer to 18 million homes—more than double the official count.


The problem? FEMA’s maps don’t account for extreme precipitation events, leaving millions of homeowners unaware of their true flood risk and therefore uninsured.


“About half the people with significant flood risk aren’t mapped into FEMA’s Special Flood Hazard Area,” Porter explains. “This leads to massive underinsurance across the country.”


What This Means for You


Whether you’re a current homeowner, potential buyer, or real estate professional, these trends will likely impact you:


For Current Homeowners:


  • Review your insurance coverage immediately
  • Consider flood insurance even if you’re not in a designated flood zone
  • Budget for potentially rising insurance costs

For Potential Buyers:


  • Factor climate risk into your home search
  • Expect tighter lending conditions as banks wake up to these risks
  • Prepare for higher home prices and interest rates

For the Market:


  • Lending practices will likely become more stringent
  • Property values in high-risk areas may face downward pressure
  • Insurance requirements could become more comprehensive

The Path Forward


The solution isn’t simple, but it starts with awareness. Lenders need to integrate climate risk into their underwriting processes, even though this might make homebuying more challenging in the short term.


As Porter notes, “It’s going to increase the price of homes. It’s going to increase interest rates.” But the alternative—widespread foreclosures and financial instability—could be far worse.


Updating flood maps alone could cost $11.8 billion according to industry estimates, but this investment pales in comparison to the projected losses from inaction.

The Bottom Line


Climate change isn’t just an environmental issue—it’s a financial crisis in the making. As extreme weather becomes more frequent and severe, the traditional approach to homeownership and lending is proving inadequate.
