Deciphering this property's public record

[Zachary Helfer]

I have been researching a property and found some interesting information on Zillow. I know that it is screaming SOMEthing odd is going on, but I am too inexperienced to tell what's going on.

Seller is currently asking 23k off-market. Zestimate is 75,630 and realtor.com estimates it at 53,100. Public pricing record shows it listed at 55k on 8/17/09 then removed on 3/23/11. It then says 7/29/14 sold for 6,400. A link to a public record from the county auditor is listed there.

I have been trying to decipher the acronyms and jargon under the sales information and notes sections to piece together the full story. Does anyone know what these sections mean, namely the two grantors both on the same date (double close?) , the Sale: P, Not Probable PR, and any of those notes? Hopefully posting this link is in good taste, I am just trying to learn and not necessarily monetize this information. http://fiscalweb.summitoh.net/clt/refintg2.opt?LIE...  

Thank you very much for your time!
