Echoing what @Andrew Beauchemin said, you can find out owners of buildings by looking at property tax records on your county's appraisal site. if the owner is a LLC (which is usually the case for larger multifamily), go to your state's secretary of state website and look up the business in the business records search. i'm not familiar with pennsylvania, but that's how every state I've looked at before operates. there is usually an agent of record who oftentimes is the owner, however, for a larger, more sophisticated owner, it could easily be a lawyer or someone else.if that fails, a broker is your best bet. they'll have the relationships with owners and other brokers you need. as others have said, it's hard to go off-market without a track record, but maybe by showing your current portfolio and explaining your desires, you may win someone over :)

Then call some contractors for things like paint and carpet.I know some buyers active in Vallejo PM me if you want contact info

I bet you can get pretty good eye's on some areas of Huntsville using Google Maps.

@Jared Huffman,Find direct comps that sold, and are actively listed!   

His website is hardcorecloser.com and he has a really active facebook group called Sales Talk for Sales Pro if you're so inclined.Hope this helps!

I also love the drier climate and mountain activities available in the region.

However, I'll bet it will come up when the property is finally sold in a more conventional sale.  

Zillow openly explains this at https://www.zillow.com/zestimate/ and publishes their median error rates and other stats for some major metro areas at https://www.zillow.com/zestimate/#acc.The good news is, it's relatively easy to validate how accurate it is for your market:Have your realtor pull 50 or 100 active and sold homes in the market/neighborhood you want to analyze.Compare actual asking and sold prices to the Zestimate for each one, put them in a spreadsheet, and develop some averages. 

Greenville has super low inventory and lots of institutional investor activity.  

It would not allow me to tag him on this post, but he is active on BP.
