If your'e considering purchasing a home with foundation issues, I'd get an estimate for repair, anticipate plumbing repairs (post foundation repair) and take a look at the degree of the repairs; for example if you're adjusting the home an inch or so throughout it may be something I would consider, however, if you're dealing with a cracked slab and/or adjusting the home over 3" then you may want to rethink.
