Our local Craigslists always have "Property inspector" jobs listed. You go take some cell phone shots of buildings to prove they exist. The people I have spoken to who have done those say they didn't bother going to the places as often as not and took pics of some neighbors house. Even when people actually do that job and document the true state of these properties I can't help but suspect the information is buried or lost because thats not the narrative management would want.
The actual family owned housing stock got better the last two years, our population doubled for the last 3/4ths of 2020, and all those relatives did a lot of renovation and rebuilding.
