I don't really get this mentality. Yes, its good to have your home go up in value, but when you sell, are you moving to South Dakota? If not, then the houses your hoping to move into have ALSO gone up in value. The difference being that nobody can afford 'starter homes' at the low end, so people have a harder time selling them, and moving up to a nicer house.
A lot of people view their home as part of their retirement plan. Buy house, raise kids, retire and sell house. Buy new house outside of work center. House prices in places like Redding CA are in the 200K range. Same house in the bay area is around 1million.
To me it certainly seems worse than other retirement approaches. You are forced into making a single asset a huge percentage of your net worth, which utterly destroys your diversification. Real estate is also notoriously illiquid, so if something forces you out of the area, you could take an enormous loss.
If someone proposed another retirement investment strategy with these characteristics that didn't involve your home, people would say, "I'll pass... that sounds like a really bad deal."
