public records - Listings. how to ?

[Justin Heitter]

Hey guys, there is a house a few blocks from me that I am interested in .....It appears to be a 4 flex and is super run down...It looks kinda dumpy....But with the proper tlc and someone who actually gives a damn about it, it could be nice.  It is not for sale.

My question is :  how do you search for a property....and get ahold of the owner?  How can find a location in the county records and information about it, the seller, the rents if any, and any other stuff about the property??
