FWG,

There are a lot of sites that support house exchanges, but they are oriented toward short-term vacations. There is one possibility that I am pursuing: house exchange with seniors. The site is seniorshomeexchange.com. Younger persons often can't move for just one year, but a retired couple has more flexibility. Right now, they're having a $49 special.

Have you considered renting your house? There are lots of complexities: storage for your items; tax implications; property manager; etc. But you might find a way to make it work.

Good Luck.
