I haven't done any scientific research on this subject, but anecdotal evidence tells me that:
(a) If someone in financial precariousness could sell a property, they would.
(b) If someone in no financial precariousness could sell a property at a really nice profit, they would.
(c) If someone in no financial precariousness could sell a property at a small profit, they wouldn't. SoWal is too awesome to give up.
(d) I have a family member with a really nice beach-near lot who has held off on building because of the hurricanes and not being able to at minimum break even if they were to decide to sell.
I mean, we've talked about buying a beachfront condo and selling our home, but then we'd be back in the baby-poops-in-pool-closed mode or having to pack up to go to the beach. I'd rather just sell and rent than go back to those inconveniences.
How does this relate to hurricanes? The arrival of a hurricane takes both an emotional and financial toll - boarding up (or spending a kajilion dollars on hurricane shutters), wondering if your home will still be intact when you drive back to inspect it after a hurricane. Every time we leave our home after boarding up and arrive after the storm, we're on the verge of puking. It's very emotional.
We've decided that we're strong enough to deal with it, although I don't know if we'll feel the same way in, say, ten years.
In the meantime, our house is always on the market at a price that we cannot refuse (as in The Godfather ).
