Month to Month Leases in PA
Hello everyone I need advice! I am about to move into an apartment and sign a month to month lease. I live in PA and I filled out an application about 3 weeks ago and the landlord and I have been in close contact for at least once a week. Well every time I talk to him he asks me for different things. For instance when I filled out the application he didn't ask me for a fee or anything. I am a single mother of 2 children and he asked me for my children's birth certificate and I thought that it was very weird of him to ask me for those things. Well I supplied those things and he also asked me to make up a paper and sign it so that he can check my background. My problem is that he didn't ask me for these things when I filled out the application. He just keeps on adding on different things every time I talk to him. To make a long story short I want to know what is the law of month to month leases in PA. Also am I liable to pay for a background check when he never asked me for any money when I signed the lease and he just added that at the end? Shouldn't he have asked me for everything in the beginning?
Thank you for your time!!
