I live in Maryland and have a 1 year lease. I received a 30 day notice to quit because my landlord received rent late twice. The first time that they received the rent late is when I first moved in and the address that I had to send the rent to was an insufficient one. The second time the rent was late and I included the late charge which is a condition of the lease. I was never given a warning that this was a problem and the 30 day notice to quit does not give time to correct a problem. What I need to know is do I have any rights?
