Realtor.com® Flood Risk Data Tool

Louisiana REALTORS • September 14, 2020

For REALTORS®, more knowledge is more power.

Realtor.com® recently released a new tool on its platform - an addition that enables you to see the flood risk of both for-sale and off-market properties. The tool combines data from the Federal Emergency Management Agency (FEMA) and the First Street Foundation's Flood Factor™ feature to produce a risk score ranging from 1 (minimal risk) to 10 (extreme risk) and an indication of whether that risk is increasing, decreasing or constant over the next 30 years.

In addition, a graph shows the cumulative risk of flooding for a property over the typical 30-year period of ownership, along with the FEMA-categorized flood zone for the property, and whether flood insurance is required. 

This information can be used by REALTORS® to provide additional context, guidance and insights to your buying and selling clients.

This new tool allows REALTORS® to:
  1. Make this risk an early part of the home search discussion.
  2. Enable buyers to factor this risk into their evaluation of a property.
  3. Incentivize owners to make necessary home improvements to mitigate flood risk.
  4. Help buyers and owners ensure they have adequate insurance coverage.
  5. Reduce the likelihood that a home sale is derailed by unexpected flood risk information late into a transaction.
Here's how the data from both sources (FEMA and Flood Factor™) will work together to help you as a trusted REALTOR®:
