It doesn’t sound like you generally have problems with your home, and if you do, have you tried to work it out with the builder first?
You might also want to ask other piggs more knowledgeable, but…If you are part of a construction defect lawsuit you might have a few drawbacks.
1)If you plan on refinancing with a pending lawsuit, that *might* be a problem or if someone else is trying to buy, that might be a problem from loans.
2)Suppose that you retain the firm, the firm lists a bunch of stuff that is considered “defect”, and then after lawsuit is said and done, you get a few hundred or a few thousand after legal expenses…Not nearly enough to cover anywhere close of what they documented as a “defect”…Now you decide to sell the home…(a)Don’t you have to disclose what the law firm found?….(b)If so, then isn’t the next logically thing the potential buyer going to ask is “did you fix all those things they found were defects?”
