Unlike owner-occupants, owners of rental, second, and vacant homes don’t factor natural disaster risks into prices.
Absentee landlords own about half of all homes in flood-risk areas.
Overvaluation in flood zones would drop at least 15% if these properties were priced like owner-occupied ones.

The French insurance system is financed through a 20% additional premium on home insurance premiums and operates through a mechanism of cross-subsidization from low-risk areas to high-risk areas.
It benefits:
🔹second homes in the case of flooding
🔸owner-occupied homes in the case of subsidence

🔸Owner-occupied homes owned by middle income households are more exposed to subsidence.
🔹Second homes often owned by wealthy and diversified households are particularly exposed to flooding.
