I'm the OP—just chiming in, I can just hardly live off the rental income I make, but its a lot less than my salary as a senior SDE. Yes what I am is not analogous to someone renting out a few extra rooms. I just think my experience is analogous to that of a small time landlord in that I know each tenant very well and we have good relationships—and I manually handle each part of their tenant experience. To add more detail, I share a bedroom in a 25 bedroom house that I own, which accounts for a bit more than half of my tenants.
