Let me be the first then. I've been a landlord for a decade. I've paid back each and every one of my tenants the rent I collected in surplus to costs. Adjusted upwards to reflect the appreciation of the unit.
I now rent at cost, choosing to believe that it's better to help the people who live with me establish themselves and build financial safety.
In some cases we have rented a mother in law unit. Are different apartments in the same building under the same roof?
I tend to be broader about community then many folks in the States. Imo, you live with the people in your local area, whether that's house, apartment building, or block.
I was inspired by someone else who did it and posted about it on Reddit somewhere a long time ago. So there are at least two, but likely many more than two of us out there.
