The problem is that typically you buy a house attached to a piece of property. So if the house is 20 years into a 25 year life, you have an issue of trying to 1) dispose of the house at the 25 year mark, and 2) finding a place to live for several months while the house is demolished and rebuilt. The only way this would work is with manufactured homes. Even then, I haven't heard of anyone having their existing home hauled away while a new one is wheeled in place the same day (except on the lower end, with park model campers).
