Why Does Redfin Show a High Wildfire or Heat Risk Score on a McKinney Listing When Zillow Doesn't Show One at All?
Why does Redfin show a high wildfire or heat risk score on a McKinney listing when Zillow doesn't show one at all? Redfin and Zillow pull risk data from different third-party providers with different coverage and methods, so a McKinney, TX address can show a scary score on one site and a blank space on the other.
If you've been house hunting anywhere in Collin County and bounced between Redfin and Zillow tabs on the same listing, you've probably hit this exact head-scratcher. One site flags a property with a bold red "high wildfire risk" or "extreme heat risk" badge, and the other simply doesn't mention it. Naturally, your first instinct is to wonder which one is lying, and whether you should walk away from an otherwise great house in Stonebridge Ranch or Craig Ranch because of a number you don't fully understand.
The honest answer is that neither site is necessarily wrong. These portals license climate and environmental risk data from outside research firms, and those firms don't all model risk the same way, cover the same geography with the same detail, or get rolled out to every listing at the same time. A score showing up on one site and not the other usually says more about data licensing and coverage gaps than it does about the actual physical risk sitting on that lot in McKinney. Before you cross a home off your list because of a single alarming badge, it's worth understanding where these numbers actually come from and how much weight they deserve in a real Collin County home search.
