My landlord just informed me that he wants to put the house up for sale at the end of the current lease. He wants to send a photographer to take pictures of the house, including our personal belongings, to use in promotional material (flyers, web page). We told him we were very uncomfortable with the idea, we consider it an invasion of our privacy, and asked him not to do it. He claims it is in our lease: we must let his agents, prospective buyers, etc. into the house with 24 hour notice, but it says nothing about taking pictures and making them available to the public. Can he force us to comply?
