Real Estate / US tax obligations on Polish real estate [2]

I am Polish and a naturalized citizen of the United States with property in Karkow. What kinds of Polish real estate documents are required by the US Internal Revenue Service for me to pay income tax on income generating property owned in Poland? How do I locate a professional in Poland that understands my requirements for these documents required by the IRS? What Polish documents do I need for the IRS when I sell the Polish property?
