I disagree with Florida "dodging a bullet". Two people on my little street in Michigan, lost their Florida homes (Everglades City and the Lower Keys). Even if it look like an intact building, you never know what kind of water damage has occurred inside; and many folks didn't have Flood Insurance. Even my own condo, "safe" along with the others in our big strong building, could have suffered a terrible fate: due to the sewage Lift Stations being without power, we had a back-up, which fortunately, stayed within the confines of the kitchen sink (which then plugged up). Imagine if my neighbors had not checked our place to discover that and what a hellish smell that would have been after mellowing for another 6 weeks before we got there?
I realize there are thousands who would trade their demolished homes for my stinky sink - but the point is that just because you see a building that appears "fine" - it might not be.
