On March 13, the company announced it will include three new climate risk factor scores on property pages: heat, wind and air. Using a 1-10 scale, the portal will display current risk factors for a property as well as the expected change for each risk in 15 and 30 years, the length of a typical mortgage.

Climate risk on the minds of buyers — and insurers

The new tools come at a time when most buyers are weighing climate risk when shopping for a home. And with destructive climate events on the rise, some insurers are no longer offering homeowner policies in high-risk areas, or are sharply increasing insurance rates in those regions. 

Climate risk data can help buyers weigh the benefits and potential downsides of buying a home with a higher risk factor.

What the risk scales show

Heat factor indicates how many days a property experiences a heat index at or above the local definition of a hot day, what the high temperature in the hottest month actually feels like, and how the heat index is expected to change in the future. According to, nearly a third of U.S. homes will experience "severe or extreme" heat this year.

Wind factor assesses property-level risks of being exposed to wind gusts exceeding 50 mph. estimates that around 18% of homes are at risk of hurricane wind damage in 2024.

Air factor measures poor air quality days, defined as an AQI above 100, which is expected to affect about 9% of U.S. homes this year.

How agents can use the data

While agents may be concerned that risk information could make it harder to close a deal, said the data will improve transparency and help agents provide their clients with accurate and actionable insights. 

For buyer agents, the company said, offering the information to clients could help buyers avoid unknowingly purchasing a high-risk property, or enable them to decide whether they're willing to accept the risks.

And for listing agents, the data could give their sellers an opportunity to mitigate potential risks before putting the house on the market.

"It may also help reduce surprise costs related to insurance by helping buyer and seller clients perform better due diligence and plan accordingly," the website stated.
