As a matter of fact, one of the parents asked me if the room is occupied by a female student or not.

Both of these solutions would still have a solid-sized living room.

(She can live there, and we can rent out the other two rooms)-Is there a way to put the property under my name/share the title with my mom instead of "buying" it?

That home is now a rooming property yielding $1400/mo

(Bad faith retention)Other things that have happened over the course of tenancy, which I understand has nothing to do with the Security Deposit, just wanted to give you the full picture of who I am dealing with: - She attempted to AirBnb one of the rooms, AND the entire apartment for when she would be on her boat (2 separate listings) without my permission. 

I've considered having them vacate in order to AirBnb each room.

Paying anything less than a grand you are betting on getting nothing than warranty issues.

Should I list each room separately or list the whole apartment and let the tenants figure it out?

I struggle with whether I should take some money off the table and sell off some properties, reinvest in other areas that cash flow with some more room to grow on the apprecIation side, or just play the long game and ride it out.

The partner’s sons will not trouble you much, but look out that some boys poorer, much poorer than yourselves, whose parents cannot afford to give them the advantages of a course in this institute, advantages which should give you a decided lead in the race–look out that such boys do not challenge you at the post and pass you at the grand stand.
