Returned yellow letter

[Alex Verdugo]

I have been sending out yellow letters for the past week or so. Usually about 4 a day just to get my consistency up until it becomes a habit.  So one of the letters came back as "return to sender, attempted - not know, unable to forward".  According the the county website the property is owner occupied.  

What are the possible reasons that it would be returned?  There weren't any hand written notes on the envelope to indicate that a person declined delivery. It simply looks like a standard computer decision to not deliver.

What is the next step in finding the owner?. I did a property search by his name and the only one to pop up was the property I already sent the letter to.

Is there another way to find out the status of the property? I'm not sure if its gone to foreclosure, its in probate, whatever. 

Like I've heard so many times on the BP podcast, go the extra mile and thats where the best deals are. So please help me finish this mile of the journey.
