My question involves landlord-tenant law in the State of: Indiana
I was given a letter by my landlady on February 14, 2017 stating she is selling the property and her closing date is March 27, 2017. In the notice she stated she was keeping our security deposit as March 2017 rent. She also request we be out by March 25, 2017. Our lease expired and we are currently on a verbal month to month lease and are current with our rent.
We found a place to rent beginning March 1, 2017. We called the landlord and left a message on February 21, 2017, to see if she would do a walk through early so we could get our deposit back for the new place. She had not returned our call and we called again on February 25, 2017 and left a message. On Friday 26th, we received a letter in our mailbox stating she gave us over 30 days notice so we didn't have to eel rushed,, we were rude, and she still has to do a walk through and check for normal wear and tear. Needless to say, we were unable to move out by March 1, 2017.

My questionson are:
1. Can we expect to receive a refund from the prorated rent for March, if we mover out earlier than the date she gave us 3/25/17?
2. Since the property is closing on 3/27/17, can she legally keep the security deposit?
3. Do we have any recourse for her non compliance of our request for an early walk through which caused us to not be able to move March 1, 2017?
4. Can our landlord use our security deposit as the last month's rent?

Thanks.
