The son installed it there so his elderly (now deceased) mother wouldn't have to walk the steps. 

Add to that a basically exploitative model based on stealing equity from uneducated or elderly sellers I would argue this whole business model needs to made illegal with no ambiguity.

Another factor that is important to look at is how many renters are retired/elderly.

You might call some companies that do elder care in those smaller home settings- perhaps they're looking for places like this.

Buying a house near an elderly person is always good.

The home does have a section 8 elderly tenant in the home who has been paying for rent for 20 years.Any ideas on what I can do here, it would be nice to take it off her hands maybe assume the note?

if you appealed to an elderly tenant if could be a viable proposition.If anyone has ever had aging parents who insist on living alone a housekeeper/maid would be a great idea.A couple of Gay friends of ours did just that with their respective active mothers who were already good friends.

Even pre-covid it was closer to $100k to get rid of tenants who don't want to leave (and that assumes they were willing to be bought out, there were only a couple of them, none disabled or elderly).

Elderly?

Maybe you could figure out a different niche like student housing at UNC Asheville, vacation rentals, mobile homes, housing for elderly since a lot of people retire there, etc.
