Legal Question in Landlord & Tenant Law in Massachusetts

First, the lease is a binding contract so you have to let her move in unless you go to court and get a court to void the lease.

Second, installing cable is not putting in a dish on your roof. Without reading the lease, I cannot tell you if she violated the terms of the lease. One thing you should put in future leases that no satelite dishes may be installed.

You should check now what the cost of fixing the installation of the Satelite Dish is and determine if the security deposit is sufficient to cover the cost.

As to the actions of her daughter and boyfriend, is the daughter going to live in the home?

I would get her to sign an agreement that says if the daughter or boyfriend damage the property by abusive action such as kicking a door or breaking windows etc. that she agrees you can terminate the lease upon 30 days notice.

I would also get her to sign an agreement agreeing she is responsible for the repair of the door and any repair to the roof needed due to installation of the satelite dish. It would be better if you can state the actual amount and get her to pay it now.

If you wish to discuss the matter further, please feel free to call me on Tuesday or email me at any time.
