Abandoned Property

Myself and my husband have been living in a two bedroom rented apartment for the past four months, we signed the lease for period of one year. Recently my sister got a job in the city and wants to move in with us for a month. But my landlord is refusing to let her stay, saying that there was a clause in the lease agreement which prohibited outsiders from staying in the apartment for more than fifteen days. Will I violate the terms of the lease if my sister stays with us?

I am living in a rented apartment in downtown New York. It is an old apartment built in 1950s. Due to the recent earthquake huge cracks have opened up on the walls and ceilings and floorboards have broken away in many places. I want to move out of the place but my landlord is insisting on me paying the rent for the rest of the lease period. Does the law require me to pay the whole rent if I break the lease?

I moved into an apartment in White Plains, New York about two months back. In the lease agreement signed by me, there was a provision stating that the landlord had undertaken all repairs necessary to make the apartment fit for living and the tenant is completely responsible for the maintenance of the house from the date of handing over of possession till the expiry of the lease. It has been raining for the past two days and I saw that the roof is leaking resulting in my living room becoming wet and damp. I never expected that the apartment would have such major problems. Can I force my landlord to pay for the cost of repairing the roof?

Our tenant, who was on a month to month lease, sent an email on 3/4/14 stating that she vacated the premises as of 3/2/14. She did not give 30 days prior written notice, therefore violating the terms of the Lease. She stated that she had movers come in and move everything out and leave the keys for us in a drawer in the kitchen. When we went to the home yesterday, 3/5/14, there were several pieces of big furniture, and lots of other items left in the home, along with lots of trash, dog urine ruined carpet and floor boards. Are we, required to store those belongings for a certain period of time before we can dispose of it all? Or, because the Tenant stated that she vacated as of 3/4/14, are we legally able to dispose of all remaining items so that we can begin the work it will take to return the home to a habitable condition?

I own property in which there exist a Mobile home, the person living in the home had been paying lot rent. I find out that he moved away and left the home. This mobile home has been on the property at least 10 years, maybe longer. This is also the only mobile home on the property, it was there when I purchased the land which I use for another business. I agreed he could stay just pay lot rent which he did and does not owe any money to me. The mobile home does not belong to me, it is abandon and he owes $26 grand to the mortgage company. The home is also in a place that moving it will very difficult. I want to charge the mortgage company storage fees. What do you suggest?
