I haven't gotten rid of mine. Sometimes I'm tempted to, but I doubt I ever will.
My relationship with rentals is a mix of love and hate, as I'm sure many landlords can understand.
The tax benefits and streams of income (when they aren't eaten up by repairs and maintenance) are great, but they do complicate my tax return and accounting, and they weren't really reliable as a source of income until I owned several of them.
It's one of those REI strategies you have to either go all-in on, or don't bother with them at all. A lot of people like to dip their toes in the water to try them out, and get frustrated when they don't deliver all the freedom and income they thought they would get. They can be great a great source of income, but most people won't see the full benefits unless they chase after the dream with everything they've got.
