Major Non-disclosed Issues - HELP

[Emily Smith]

Hi all! I just bought a SFH a week ago and am not discovering MAJOR plumbing issues throughout the entire basement (botched bathroom addition, horrible French drain system, drilled holes in the sump pumps…) that has resulted in the whole basement concrete/subfloor being saturated. Somehow, my inspector didn't catch any of this - will obviously not be using him for anything else. The sale has gone through but none of those stuff was disclosed, including the work done on the basement where stuff was clearly done illegally and not up to code in various places.

Is there anything I can do here? It’ll be $70-100k to rip out all the basement flooring and redo the sump pumps and pipe work. Is there any RE equivalent to lemon laws or anything at all that could save me from ripping my hair out right now? This is my first property and it’s in Virginia in case there are state-specific saving graces anyone knows about
