Make sure you're looking at all the costs. I had basically the same choice to make about my mother's house, with very similar numbers... except that the city requires an annual rental inspection and registration, the property taxes would almost triple going from the current owner-occupied rate to the higher rate charged on non-primary residences, and the insurance on the property would go up (though only slightly) as well. So instead of the ~$800 I'd originally estimated I could clear based on the current upkeep expenses on the house, I'd be looking at closer to $500/mo in profit - nothing to sneeze at, of course, but a low enough number that it could easily be eaten up by repairs, legal costs, etc. That's not enough to be worth the risk/hassle, for me. The only way I'd have done it is if we wanted to hold on to the house for ourselves or one of the kids to call home in the semi-foreseeable future, but once we ruled that out, selling just made more sense.
