You are living next door for a year so your choice to rent to someone may have a direct impact on your life (unless you are not home most of the time).Cheers and good luck!

The long-standing average here in Milwaukee is $200 per door.

I agree with @Michael Baum.I recently had a guest who lit fireworks and put the hot shells in the outdoor trash can which started a fire and burnt up the garage door, stucco, and facia before it was put out. 

Oh boy, another post about what amount of doors equals x amount per month

I found this odd, so I decided to call Cobb County and they advised that a basement can only be rented by one adult with some kind of square footage per person limitation, and I could not wall off the basement door.

When picking a market, I would recommend first looking at whether or not the state is landlord friendly and then the macroeconomics (population & job growth / any additional drivers that are helping the local economies) of the various cities you're potentially targeting.

Some settling of a property is to be expected but if it significant enough to be causing issues such as slanted floors, door openings not being square, windows that won't open, etc.

I also have no lawyer so, requesting of tenant to contact with my lawyer is not an option.There is only one window in the unit because of the layout of the unit, it is not zoned as legal unit so it looks like one big corridor with a door on one end and window on the other end.

Personally, I own 137 doors and am happy to weigh in!

I also have just recently broken through having a dozen doors.
