@Matt MichaelsonOther residents are elderly and probably haven't looked at their attics.

The things we are considering; My son needs to live in his home for 4 months before renting it out [Nationwide insurance requirement] so he is planning on meeting his neighbors during that time, having coffee, lemonade, and cookies on the front porch and welcoming all to help themselves a couple hours a day, joining neighborhood watch, and he and my grandsons are already planning to ask a few of the elderly homeowners if it would be alright to paint or fix their fences or whatever [small stuff] Would these be good things?  

I can't speak for other locations, but for everywhere I've looked within 150 miles of me, most of the properties I look at come from elderly family members passing away and leaving behind a house with a good bit of deferred maintenance.

It doesn't matter that you didn't know or that you didn't intend to.You need only one complaint, particularly from a vulnerable party (elderly, black or other minority, someone deemed "incompetent", someone in bankruptcy, and on and on - then they pile on the charges.

And, what's more, she's friends with the elderly lady who lives in Unit 6.

He does this with SFHs, in our neighborhood one was a foreclosure that is now very nicely remodeled (he lived there during the process), and another was the home of an elderly person who had died - he fixed it up and made it a rental.
