If you are real laid back and don't care what stupid crap the renters do, then rent it out.
I had a duplex in the early 80's as my first house so that I would have rental income to offset the mortgage payment that was 12.5%.
Once I could afford to, I quit renting out the other side.
But did come to the conclusion that if I did have to rent out anything,
the best tenant is a not so good looking girl with no boyfriends.
