I was looking at some model homes and spoke with one lady who lost her house. She indicated she was caught up in the appraisal process–the insurance carrier thought the property was worth less than what was owed/insured for, so they only paid what it was worth, not the policy limit even though it was completely lost.
Anyway, she said that both she and her neighbors were going to rebuild, but it was taking months to come up with plans (they were all looking at model homes for ideas). My guess is that most of them are content renting while they come up with their house plans. The insurance companies usually pay for housing expenses for a certain period of time–maybe they are living this up.
