How do you know if a property has been inherited?

[Victor Barboza]

Hi everyone! I was driving around a neighborhood in Phoenix, AZ. I found a decent amount of properties that could be potential leads. However, there is one that stands out a lot to me. It has boarded windows, the mailbox has been nailed, has normal wear, but nothing to big and looks like it could be a great deal. I looked into the home and found the owner using my local tax assessor's website. I proceeded and looked up the owner on white pages, and figured out that he was really old mid 90's. So, I took a yellow letter to the home and put it on their door since the mailbox was nailed. Got no response, did it again two weeks later and again no response. I asked a neighbor if there was anyone living in that property or what was the deal with it. They let me know that they have not seen the original owner in a while, but other people had moved a sofa in a few days before.

How would I know if this property has been inherited? There is also no other mailing address for the homeowner when I look on my tax assessor's website. Is there any tips or tricks that have worked in the past for you guys?

- Thank You!
