I would be careful when you say that "all landlords" capitalists because that is the Fallacy of Hasty Generalization and the Fallacy of Jumping to conclusions.
We did not purchase either of our two rental homes with the intention of renting them out to make money. The one rental was our residence for 17 years and we moved because we needed a larger house at that time, but that was in 2008 when everything tanked so we could not sell that house for what it was worth so we decided to keep it and rent it out because one cannot have a house that sits vacant...
We purchased the other house for a vacation home and an investment since I had lost my job die to state budget cuts and I got demoted into a much lower level position with much less pay... We had to rent the vacation house because one cannot have a vacant house since insurance won't cover it.
Technically, if you're making an investment, that can be considered a capitalistic venture, so I wasn't entirely incorrect. Granted, you wouldn't be at the same level as other capitalists who are the movers and shakers in society and exert a great deal of influence over media and government.
As I explained in a post above to Revoltingest, my dad and step-mom kept their old house when they needed a bigger house. But it was a lot of headache, and after 10 years of doing that, they called it quits. It was more trouble than it was worth. From what you've been saying about your own experience, it seems the same - more trouble than it's worth. Why go through all that? It just seems like a big headache. Is it really worth it?
