Psst...If there's a lock box on it...there's something "active" going on. Realtors don't leave lock boxes behind.
Bet he's got a record.
I think the lock box and sign have been gone at least since the City mowed the lawn around April. At that time the City and our HOA were searching for who is responsible for the property.
Tomorrow I’m going to try to get a copy of what ever it was he filed with the county or at least find out his full legal name.
