I felt very sleepy a lot of times in class and had to fight off falling asleep - even more than from the usual boring class.  

What if you get a problem tenant that stops paying and fights eviction?

I have been investing in single family homes exclusively.  The thought of a multi-family building quite honestly made me nervous.  More tenants, definitely bigger numbers and property managers.  It seems my investment...

There is always drama - moving boyfriends in without permission, fighting, smoking (and fires that go with it), often unable or unwilling to pay the tiny amount of their portion of the rent, not paying utility bills, helpless to do minor maintenance, unpermitted pets, frivolous inspection failures... after all this, when they finally leave, you have to rehab the entire apartment because it's trashed.   

Why fight with someone over $100 if they are paying 15K, 18K a year and are long time tenants.

I really wouldn't worry about her leaving much.Keep her deposit and give it to the new owner as compensation for losing the tenant if they get upset about it.Let the loser go without a fight so she doesn't trash and damage the place on the way out the door.Tell the new owner it's a wonderful opportunity to raise the rent for the next tenant.

Feels like everything is an emergency and you end up fighting fires from the time you get up until the time you go to sleep.

I know fighting mice is tough going. especially if behavior encourages it.

Sure you could . . . you'd forfeit your security deposit if you broke the lease, but I'm sure if you had a conversation with your landlord and explained that your options are to stay and fight him or leave and move out, he'd be willing to negotiate on the deposit issue.
