"Owner" doesnt own rental

[James Johnson]

Ive been staying in this house for over 18 months. Recently did a search and found the taxes (up til 2 years ago) was paid for by a finance company, then they quit paying them. I tried to find info on this company to possibly buy the house, or atleast find out more info.  Found out this company was merged with CitiFinancial.  Cant seem to get a hold of anyone with a clue.  The guy who claims he owns the house is and never has been on any paperwork ive found on the house. Im afraid to pay the taxes, then have the house taken.  Ive looked at adverse possession, but not sure what steps i should take... "color of title" and all that. IMO this was an abandoned house.
