Should I pursue this vacant property?

[Kyler Pace]

Back in August I found a vacant property in a good neighborhood that I thought was worth looking into. I have been able to contact the owner, and found out that it has been vacant for the last 8 years. The owner said that he did a voluntary foreclosure and gave the house back to Bank of America. After that happened, B of A lost the necessary paperwork, and then sold the loan to Ditech. All of the county records still have the original homeowner listed as the owner of the property, but nothing is happening with the property other than it continues to sit there vacant. The owner gave me all of the contact info for Ditech. I've read that Ditech is difficult to work with, so I'm not sure this is a situation I should even contact them about. Any advice?
