Has anyone ever gone through with a foundation fix?

[John Collins]

This has been the biggest red flag with under market properties that you wonder ... well, why can they be had at a certain price, and everyone avoids them because of how costly and risky foundation fixes are.

My question is, has anyone actually done a major foundation fix? What was the procedure, what was the price, and are there any videos online that give you an idea of what to expect contractors to do?
