Taxes

[Rida Vulic]

I am a US citizen living abroad for almost ten years now. I am planning to buy property as an investment in Chicago. My question (amoung many) is whether or not I am able to claim non resident and get a cut on the tax. Also, I would like to make a cash purchase and avoid loans and mortgages, if I bring in a substantial amount of money to my US account with verification that I have sold my property abroad, will I be taxed on that money as well.
Thank you in advance for any suggestions and help.
