In my case they have helped with rent, cared for the tenant when required, moved them, and even cleaned out the apartment after the elderly tenant died.

The risk of driving or flying on a plane also doesn't exponentially increase among elders like it does with covid-19.

I mean geez when I was a kid I can remember only a blind person An elderly widow or a guy that got hit in the head with something at work was sitting at home on disability .

He now owns several in the street he resides in because he was tired of them deteriorating & attracting groups of kids etc.He then did the 'rent to own' thing with several of his elderly parishoners & in fact maintains them with a landscaping crew etc.He finally admitted it will be a nice retirement income boost when the time comes.

I know I didn't hear that from the elders I talk with.

It hastened the deaths of hundreds of thousands of the very elderly who would have died within a few years, and it hastened the inflection point at which maturing families decide to leave NYC, as they always have within a few years. 

And here's why: As @Nick Elder points out, in just the past month, we've seen 6.7% appreciation for SFHs in Denver and almost 20% in the last year.

I only own one house there and it is rented by an elderly couple with a voucher.

At the Housing Authority we had a 15 pound limit, that takes in all the lapdogs popular with the elderly tenants we would get or others.

In fact many of the tenants in our SFRs tend to move on to purchase their own houses, whereas many of the tenants of our multifamily properties are on fixed income and/or are elderly and intend to continue to rent.The quality of tenant will depend on the quality of the neighborhood, the quality of the building, the management style of the landlord, the lifestyle the tenants are seeking and what they can afford.
