Or worse. "Forensic Files" had an episode where a creep went around looking for lone female RE agents, making an appointment to see a house, and once inside, raping and killing them.
There are attractive female agents that I know who try and bring their husband/boyfriend/brother to a showing if they don’t know the guy.
They bring a partner to an open house. And it doesn’t matter how nice the neighborhood.
A “NO GUNS” sign will actually attract illegal guns/perps.
