I can give you my opinion on this on how it applies to me. In my case and if I were alone, I would rent if possible. A single elderly woman, especially one without helpful adult kids, is a favorite target of dishonest repair and sales people. And since the roof over one's head is one of the most expensive, involved things to repair or replace, you're better off if that's someone else's problem. Sure, there can be problems with landlords, but it so happens that in my state, most renters have pretty good legal rights (except for most mobile home park tenants).
I've heard that around here, the best bet is to rent someplace that is owned by a rental company or corporation. Renting from a private person or couple, you run into the problem of the owner getting old and dying or moving permanently into skilled nursing, their family swoops in and says "We don't want to be landlords; we live miles away; so this place is going up for sale; you've got 60 days to move out."
Of course, conditions are different in different places, but good luck with whatever you decide. (I wish I could move.)
