I do hear you! We are considering FT RVing in retirement for that reason. Maybe an undeveloped lot as a home base.
The first FL home we considered buying was solid poured concrete- not block. 2 stories plus daylight basement plus metal hip roof- really pretty home. VERY storm resistant. But being near the gulf (even though on a small hill 30’ above high tide), all lenders required a supplemental flood insurance rider. THE MONTHLY FLOOD INSURANCE COSTS WERE MORE THAN DOUBLE THE MORTGAGE! Soon, imo, lenders will REQUIRE flood, sinkhole, and vanishing land riders to all policies- as the waters rise & lots disappear. The foreclosure rates will be off the charts as people become unable to pay it. JMO, MOO, etc.
