tenant left before the annual lease date

[Tina Lee]

Hi all, one of my tenant left few month earlier then lease edns date, she moved out and turn in the key to us for showing, I told her she would still be responsible for rent until we find next person to take over her lease. she didn't respond to me on email but arrange to move out date and provide us the key.

as today we find a new tenant for march 1st, however she( the old tenant who moved out earlier) did not pay for feburary rent. so i emailed her and she say she doesn't live the place anymore and she gave me the key so she is not paying the rent for a place she doesn't live.

I have her 1 and half month security deposit with me, now should i go ahead and deduct one month rent on deposit and refund the rest? she is a social worker i wander if that job will more likely make her take me to court because i kept her deposit.

she made a lot fake complaint about things same day she informed me that she is going to leave the apartment that she doesn't feel safe there. later we find out the complaint she made are all fake as well i answer the email if there is any issue she should email me first to fixed it not complaint at same day then informed me she is going to move out next weeks.

i got some crazy wave from her, what's the best aproach to deal with tenant like that? thank you
