We're in a similar situation, but what I feel bad about is not helping my parents out in this bad real estate market if we move. We moved from Austin to Dallas because we wanted to be nearer to our parents (who had previously moved from Memphis to Dallas to be near us, then we moved to Austin). Anyway, they were trying to sell 2 of their rental homes because they'd had really lousy luck with tenants and were just tired of being landlords (they're nice people and it's hard when you're nice but get taken advantage of). So, we moved into one of the houses while it was on the market. My dad also had been laid off almost a year without finding a job at this point. So, it was a very *good* thing to have the rent coming from us for the house we're in.
Well, fast forward to now, neither house sold, they rented out the other one, we're still in this one, and DH and I have decided we like Austin a *lot* better than Dallas (we already knew this, we just thought being near family would make Dallas a better location for us). So, we want to move, but I feel terrible. Moving away from my parents again, who want us to be near them and not giving them help on the situation with all the houses.
So, I know a little about how you feel!
