if one is paying $1650 a month that is like buying a $359K house (estimated).
a $359K house is very nice in itself, a person to rent at that price would probably want to buy instead.
being a manager isn't easy;
1) you would have to be some sort of a handy man or know people who are willing to do minor repairs at a discount. getting an electrician out to your property to switch a circuit breaker from "OFF" to "ON"
cost Duma $500 and a handjob (you better know someone who has a cheaper service). a plumber's visit just to find out what's wrong with your drain is about $80...cost for repair and manual labor is additional.
2) at $1650 a month does not always guarantee good tenants. these are probably good people (employed, stable jobs and etc) but have poor credit. Poor credit means they are bad at making payments, that is why they can't afford a home of their own. once they settled they'll more than likely to become squatters (promising to pay a little but never the full amount...
because law says if you accept even a penny for a month's rent, you can't kick them out.
3) eviction is a court process that is a hindrance and inconvenience, when attempting to remove renters from your property. renters never like to be evicted, they will leave your house in shambles (holes on the wall, broken glass, and full of mess).
not trying to discourage you, i just want you to rent to me, for free! ha!
