Name of the owner, but no forwarding address. What do I do now?

[Daryl Webb]

Hello Group... I thought that I would ask this particular forum that may have ran across the same problem that I just did...

I came across a property while working on signing contracts with another property across the street from the one I am trying to close on... I contacted the tax assessor and collectors offices and was given  the same name of the owner... but with the same address of the property in question, no other address, which is, by the way, board up and has been for quite sometime; per local residence of the block...

What can I do to take the name given me as the owner of the boarded up four family and locate the person who owns it so that I may get a chance to purchase this gem.????

Any one that dealt with this, I need your expertise right away... on...
