Finding the Lienholder?

[Pixie Hall]

Hello -

Foreclosed & abandoned home in my Knoxville neighborhood, been vacant 5+ years now and is deteriorating quickly. Tree fell on the roof several years ago, county removed the tree, but the roof has been open. Raccoons have set up a frat house in the attic, the yard is overgrown, etc. Original lienholder is listed as First Financial Corporation, which tanked in the subprime crisis. First Financial was bought by National City Corp. & Merrill Lynch, which were subsequently bought by Bank of America and PNC Financial Services. I have contacted ALL these companies and no one seems to hold the lien on this house.

How can I unravel this mess and figure out who indeed owns the home, and then get someone to take responsiblity for the upkeep and subsequent sale of the home? The home has become a fire hazard and neighborhood eyesore in what is a nice residential neighborhood.

Thanks for the insight!
