You just need to have a good foundation repair company and a good plumber (or multiples of each) on your team.Just watch out for the big ticket items:  foundation, plumbing, electrical, roof and AC - these can quickly bust your budget if you aren't planning to repair/replace them...Remember that the older you go in terms of build year, the more of the above issues you are likely to run into.
