Keeping Security Deposit
My tenant was on a month to month and moved out of the apartment without my knowledge with no written or verbal notice. I found out on the 13th of the month when I called to collect rent. Place was left dirty, rent was late many times during the lease, more than one person lived on the premises during the lease even though the lease said one person. Do I have a right to keep the security depaosit (equal to one month’s rent) as final month’s rent for not being given notice of tenant moving out?

Leaking roof and mold
I wanted to know how long I needed to wait before taking action against my landlord for a leaking roof? I have been in the apartment for a little over a year and it has be leaking since the end of the first month that I moved in to it. I have called him and sent him several letters regarding the situation to no avail. Currently I have many leaking areas in the apartment as well as mold growing on the ceiling in a closet. My carpet in the moldy closet is constantly damp and when it rains it is wet and spreads into the rest of the room where the closet is located. The landlord did put a tarp on the roof but due to recent weather it has been torn to shreds and is useless. What can I do to get out of this situation without losing my security (1 1/2 months)? I have been told to just leave and give him no notice, not to pay my rent until he fixes it or escrow my rent until he fixes it. I am not sure since I am on a month to month lease.

Lease Agreement
John is selling a small automotive business and the buyer (Sam) is going to continue using the current business name. The lease is to the business name but John signed the lease agreement. Sam wants to use the current lease (month to month) because he doesn’t want to sign for a year and he thinks the landlord will raise the rent.
Besides the ethical implications, what are the legal implications for John?
