There pictures you posted with this comment. Are they in the attic? Next question, is this area the only place where these stickers are? Is the attic accessible? Do they have a monitor on them?
If any of these answers are negative, I am not sure if I would live here. Also I am not sure if I would want to be the one to inspect these. The notice in the attic, where one would see it.
Even if you did not miss anything but one day you wake up and on the news here is this house. Blown apart. Not sure if I want to live with that one.
Interesting pics. Re-development of municipal (and other) waste disposal sites is not a new idea; many recreational and commercial facilities have been constructed on formerly active and now capped and reclaimed waste sites. Re-dev. for residential subdivisions is a bit less common. In either case, any sizable landfill’s going to produce, among other things, a significant quantity of methane gas for many centuries to come.
Starting at $675K for 1800 sq. ft. and up to $790K for the 2100 sq. ft model (tri-level). Zero-lot-line, gated community (which equates to association dues).
