If the OP wasn’t the target audience, then I must ask, who is? Bored 8 year olds who make financial transactions based on who can spell the worst?
If the realtor would have posted, “Hot Oral Sex” on the sign it would get equally as noticed, and still the realtor would be sitting inside staring at the paint dry.
If anything, a sign like this alienates people who just may be interested. Have you considered how many people will NOT go inside after seeing such a sign? Just how many potential clients are LOST due to such a stupid tactic?
I’m one such potential buyer, and I certainly would think twice about wasting my time with such a realtor.
