Tenant said he'd be naked when I'm doing tours for new tenants

[Jack B.]

They gave notice of move out end of March. I've had two showings in about 1.5 weeks. Usually I do an open house in summers but it's slim pickings and waiting for enough people to justify an open house is not feasible, it would take a month and they would find another place by then.

The one room mate asked about an open house and I explained this to him.

Now the other room mate (there are four of them) called me after I gave notice that there would be a tour tonight at 6 PM (2 days in advance) that he doesn't want me there, it's valentines day, etc.

I explained to him I don't need his permission to enter the house, their lease and the law requires them to allow me to show the house. Interfering with that will result in a 10 day notice to comply or vacate....

He said he couldn't guarantee that he wouldn't be naked in the house...

What to do? Serve him 10 day notice to comply?
