I have signed a lease agreement to move in a few days and the new landlord is now saying that he may want to back out of the lease. I signed the lease and submitted my security deposit, which was cashed, over a month ago. The reason is that although he promised to have new windows in and A/C units placed, he has not made it happen during the 2 months we have talked and discussed this. He calls me 2 days ago and says that his deal w/the windows fell through and b/c I am pregnant, he does not feel it will be cool enough for me. Is this legal? I am in a situation where I have no back up plan and have to be out of my current lease in 3 days. Any advice or legal recourse if he tries to pull a fast one? I am in Maryland.
