My family is renting an apartment in a private home and 1 other tenant on the first floor. For the past almost 3 years us tenants have been maintaining the home, inside and out. Nothing was deducted from our rents.as the home was being neglected. We have a new property manager who states that the home is not generating enough income(so no repairs will be made) and is storing salvaged cars in the back yard. He is stating that we should not have access to the backyard because it is a luxury.he says he can do whatever he wants with the property. Last summer our kids could not play in the back yard because as a security hazard they were forced to tear down th eold garage. No where in our lease does it state that we do not have access to the backyard. I am not on a program and i pay cash every month. The tenant on the first floor has section 8. Also we were given the apartment dirty and stuff left from the old tenants which we took care of ourselves.what rights do we have/ please help. Owner lives in brooklyn,ny
