I want to say sorry, this is a shitty situation but you arent all that fucked. Ive worked with guys that demo asbestos without PPE (unless higher ups/city inspectors were around). Not everyone gives a huge shit about this and its normal And most likely present in every house around you. First home I bought had old electric, lead paint disclosure, electrical panel in the mud room and unpermitted enclosed carport, it was a starter home, fuck it, made +50% on it. Everyone whos lived on an old campus during college lived in homes with lead disclosures. Some poster said – fix whats broke and put it on the market. This is what Id do. Next time dont look for anything you arent prepared to fix. You only got to disclose what you know.
