I am renting a condo for three months. The landlord did not go through the proper channels of the condo building (no background check or credit check which he was supposed to do) so I am not in the system or listed as a resident. He told the building I am a guest but did not tell me this would mean I wouldn't be able to receive mail and packages. Everything that comes with my name on it is being sent back. I spoke to the front desk and they confirmed that since I am not in the system I cannot receive mail. Is this a valid reason to break the lease? I told the landlord and he hasn't done anything about it. I am one month into the lease and haven't been able to receive anything at this address the entire month.
