My current lease has an automatic renewal clause that gives me 90 days before the end of a 1 year lease to inform them of my intention to vacate/change lease terms. This year I was away when they sent me the renewal letter, and they automatically renewed the lease 75 days before the end of the lease. I now want to change the lease from a 1 yr to a 6 month, and the landlord (apartment complex leasing office) flatly refuse to make that change pointing to the original lease agreement. They sent me the renewal letter 105 days before the lease ended saying this was just a courtesy letter.
Do I have no right to change the lease terms even before the new lease period starts? Isn't there something I can do?
and yes, the apartment has mice and other issues which they do not fixed.
Any help in this matter will be appreciated. I live in philadelphia.
