Also, I never allow pictures. It’s my stuff all over the apartment, and that’s private. If anyone pulls out a camera, I just say “no pictures, please.”
I once had a broker try to come on shabbos because I didn’t answer the phone. He accosted me when I came home, with a prospective tenant, and asked if he could come in and see the apartment. I said, “no, call my phone,” went inside and locked the chain.
