Because you are looking for something so specific, creating a direct mail campaign which focuses on exactly what you are looking for might be the best strategy.  

One of the best ways to find motivated sellers is by "knocking on doors" and "driving for dollars" and leaving/mailing hand-written notes and making notes for calls to talk to the people trying to FSBO's and rental signs and calling owners on vacant looking houses that are under maintained.Looking at county tax offices can provide you some ownership basic information on names, addresses, and possibly phone numbers and possibly a neighbor that has basic contact information.  

Fellow BP friends,If I have an property address, what is the best way to find out the property owner and its contact (phone/owner mailing address/etc)I know the property is vacant and probably in distress but I cannot have a good way to find the owner.  

I'm not interested in the property they own.The goal is to send direct mail to these people for a specific business purpose.Can someone please provide insight into good lists or bad lists they've heard about or had experience with?

If you have 8500 use 2500 to market (whether that's gas fro DFD, Direct Mail, Door hangers PPC etc.) and make an offer on EVERY house you see.

Start looking at them in Zillow if they are off market write down the address mail them a letter asking if they have any interest in selling their house.

@David Jiang,You need to give your own notice of non-renewal, Don't think for 1 minute that the prior owners notice would even hold water,, he shouldn't have given notice, plain and simple.Get it done ASAP, full either 30/60 notice per your lease arrangement, call her case worker at sec 8 and ask for copy of lease, if she or they can't provide it then she's on 30 day,, month to month and notice needs to be written, post at door, and put copy in mail and notify sec 8, given prior to the last day of the month, I usually always give a non-renewal around the 15th. 

Who are you mailing, how many are you mailing, how ofter are you mailing, what are you mailing, and what is your current response rate?

If someone comes to me, I'll send them your way.If you need help in your search or want to verify something don't hesitate to ask.For example: I have clients worldwide and things are just as easy as I e-mail them, talking on the phone.

Andrew Miller yes, right now we have slightly more property out of state than in Atlanta, but looking to change that soon...suburban Detroit reminds me of Atlanta in many ways (people are really friendly in both places), I sometimes jokingly call it Atlanta north.
