You've done a terrific job of detailing the components of each program.

Hey @Chi Lo - I actually have a video on my YouTube page about this (lookup ClosedByMo on YouTube).Regarding walls being damp and waterproofed, it means there needs to be waterproofing on the basement retainer walls (this is something you can do post-construction and the contractors would need to dig around the house exposing the basement/foundation to apply the waterproofing). 

U want an attorney NOW to explain to you in detail the laws surrounding how the mechanics work.

I am not privy to the details of that from their perspective, but I would hesitate to assume the policies are the same; I don't believe they are.

Please reach out to me for further details.   

The support team is always happy to hop on a Video Call with me to walk me through the solution if I can't understand it via email.

Use a servicing company, you don't want to be tracking that yourself and worrying about the details.

You can hire a home inspector who does report + videos.

If you can post more of the details I’d love to give my advice!

If you approached them in a way that you had a solution to the eyesore in their neighborhood they would be very receptive to talk and perhaps share contact details about the home owners son if they have them.
