This is standard when someone sells their house, as I understand it. There’s a disclosures form you have to fill out so that potential buyers (me) can see all the awful shit you would prefer not to tell anyone about. I assume you legally have to tell, though. So it’s a professional water testing outfit. I’ve never sold a house, so I haven’t done this myself before.
Damn. No one will ever buy this house. What a shame. It’s absolutely gorgeous in every other way.
