as far as insurance, after not much change in the last 20 years, it's jumped noticeably in the last couple of years. both homeowner's and flood insurance rates are posed to rise more. several insurance companies pulled out but hopefully, others will come into the state. keep up with the local/state news for that.
as far as looking at properties in flood zones, unless you are on the water or in a great location, i avoid flood zones for long term buy-and-hold.
also, i avoid wood frame homes, preferring concrete block here in termite country. however, St Pete and other old neighborhoods in Tampa Bay have beautiful Bungalow-style (Craftsmen, Arts & Craft) homes, many of which were built with old-growth pine, which is harder for termites to eat. but, yes, even in concrete block houses, the termites can still have a buffet on wood rafters, interior wood walls, and cabinets.
as they say, your home doesn't have termites (yet).
