The landscape of real estate in the U.S. and Canada is shifting. Climate change is no longer a distant threat; it’s a present reality. Rising sea levels, wildfires, and severe storms are reshaping property values and mortgage lending practices. The stakes are high, and the need for a radical rethinking of risk management strategies is urgent.

In the U.S., coastal states like Florida and Texas are feeling the heat. Flood-prone areas are seeing property values plummet. A staggering $44 billion in overvalued properties was reported in 2021. By 2024, that figure ballooned to $520 billion, according to Milliman. Homeowners are grappling with rising insurance costs, making it harder to keep up with mortgage payments. The numbers tell a grim story: properties in these regions are becoming financial burdens.

California is not immune. Wildfires are a constant threat, and their impact on home values is tangible. A study by Dr. Hongwei Dong revealed that home prices in wildfire-affected areas dropped by 2.2% after major events. This is not just a statistic; it’s a wake-up call for homeowners and investors alike.

Canada faces its own set of challenges. British Columbia’s coastal areas are grappling with rising sea levels, while the interior provinces are increasingly vulnerable to wildfires. Fort McMurray is a case study in climate impact. Between October 2022 and October 2023, home prices in this region fell by 16%. The average price dropped from $336,000 to $282,000. Over the past decade, single-family home prices have plummeted from $700,000 to $467,848. The trend is clear: climate risks are translating into financial losses.

Mortgage lenders in the U.S. are starting to take notice. They are integrating climate risk assessments into their lending practices. This shift is crucial as they navigate the complexities of financing properties in high-risk areas. The Intergovernmental Panel on Climate Change (IPCC) and other organizations are providing models to help lenders understand potential risks. However, the political landscape complicates matters. With a Republican administration, there’s concern that climate regulations may be rolled back, leaving lenders and homeowners exposed.

In disaster-prone areas, lenders are tightening their belts. Higher down payments and interest rates are becoming the norm. This is a direct response to declining property values and rising default risks. Homeowners in these regions are caught in a vicious cycle. Higher insurance costs and mortgage obligations can lead to homelessness and forced migration. The aftermath of hurricanes Helene and Milton serves as a stark reminder of this reality.

Miami is a microcosm of the broader issue. Homeowners in flood-prone areas are facing insurance premiums that could reach $7,000 annually. This financial strain is unsustainable. If left unchecked, the compounding effects of climate change will only escalate, undermining efforts to manage risks effectively.

In Canada, the situation is similar. Mortgage lenders are reevaluating their strategies in light of climate risks. The Canadian Mortgage and Housing Corporation (CMHC) is taking a proactive approach, recognizing climate risks as a key component of its risk management framework. This is a step in the right direction, but concerns about systemic risks remain.

The implications of these climate challenges extend beyond individual homeowners. The entire real estate market is at risk. As property values decline, investment decisions become more complicated. The insurance sector is also feeling the pressure, with rising premiums and increased claims. This creates a ripple effect that can destabilize the economy.

Both countries must adopt fresh strategies to stabilize their real estate markets. The need for resilience is paramount. Canada’s stringent building codes offer some protection, but they are not a panacea. U.S. lenders are beginning to catch up, but the pace of change is slow. The integration of climate risk into property portfolios is essential to avoid substantial losses.

Political leadership plays a crucial role in shaping the future of climate risk management. The recent U.S. presidential election has raised questions about the direction of climate policy. A rollback of regulations could hinder progress, leaving the real estate sector vulnerable. The uncertainty surrounding climate policy can lead to market volatility, impacting property values and investment decisions.

In the face of these challenges, proactive measures are essential. The real estate sector, along with banking and insurance, must accelerate efforts to integrate climate risk into their business practices. This is not just about protecting investments; it’s about safeguarding communities and ensuring a stable economy.

The climate crisis is here, and it’s reshaping the real estate landscape in both the U.S. and Canada. As extreme weather events become more frequent and severe, the urgency for action grows. The time for complacency has passed. It’s time to rethink, adapt, and build a resilient future. The stakes are high, and the cost of inaction is too great to ignore.
