This is anecdotal, but my friend’s parents are selling their 4 houses in the bay and retiring in SD. I ask him why and he said because of the weather and there are a lot more things to do here if you’re an outdoor type of people. I don’t know how many of those people are out there, but I think the timing is ripe for these people to start retiring with their riches in SD. There must be more than a few who are approaching retirement in the bay who seeks more temperate weather and have the $ to move here.
