As a foreign seller there are several things to consider. Your property is subject to a 15% FIRPTA (Foreign Investment in Real Property Tax Act) unless you currently have a US Tax Payer Identification Number, also referred to as a Tax Identification Number (TIN). The 15% is based upon the gross selling price. Additional information can be found at www.irs.gov
The other consideration as a foreign seller is the notarization of your documents. We must comply with the laws of the state in which your property is located. If you do not have access to a Public Notary, you may have to visit a US Embassy or use the Apostille process as defined by the Hague Convention.
