Heinrich is a German citizen and resident in Germany. He visits the U.S. every other year for no more than 5 days to see relatives. He inherited a significant amount of money in 2021 when his father passed away. His daughter, a U.S. resident, changed jobs in 2021 and is now an investment advisor for Portfolio Advisors in Dallas, Texas. While visiting with his daughter in 2021, Heinrich invested $250,000 in a portfolio of stocks and bonds all issued by U.S. companies. He also purchased a commercial office building in 2010 that is located in Maine. The building was managed by a professional real estate management firm. Heinrich reviewed the building during his 2021 visit with a member of the firm while visiting the U.S. Heinrich also invested $100,000 in a certificate of deposit with Fifth Third Bank in 2021. Assume there is no tax treaty between the U.S. and Germany.
