I'm with sexo, at least talk to some of the real estate property managers in your area and get a handle on cost, advantages and disadvantages. I can't see any disadvantages except cost, and of course not dealing directly with the tenants, no chance of getting a penalty blowjob if they are a day late with the rent.
Oh, and decide if you want to restrict renters, like no cats, or no dogs, maybe no Boa Constrictors, or children.
