“Displaying the probability of a specific home flooding this year or within the next five years can have a significant impact on the perceived desirability of that property,” Art Carter, chief executive officer of the California Regional Multiple Listing Service, a private database for real estate brokers and agents, told the Times.

Yea, no shit. That's the point of including climate risk when it comes to choosing a property.

Flood prone areas don't pop up overnight. The people in Swannanoa NC were living in a known floodplain that had a massive flood about 100 years ago. Same with the Guadalupe River that averages a major flood every decade. Climate change is making these events larger and more frequent, but excluding data from a real estate listing to supposedly increase home value is nonsense at best and fraud at worst.
