Has anyone done this?
We're considering a low-ball cash, sight-unseen no-survey offer for a neighbour's house (mirror of ours) that looks absolutely frightful - drooping in the middle. We'd gut it and put in a basement, probably 350K of work. Exactly how bad can it be that it would cost anything significant in the context of these kinds of works?
We'd like them to not know we're involved (unsociable neighbours), hence the stealth.
