One of my customers recently moved and I was unaware that they were going to be moving. Well I found out they had moved when i sent a statement and It came back marked "RETURN TO SENDER name MOVED LEFT NO ADDRESS UNABLE TO FORWARD RETURN TO SENDER" this is not a really big ballance but it made me think, how can i find this person that just vanished and how can i keep people from doing this to me in the future. There is no forsale sign or anything and this was the home owner. Should i contact the city to see if they have records. I do have a signed contract. I am also wondering how i can prevent this. if this has been discussed before, I apologize, i couldnt find anything under the search.
