In early 2021, the following take place:
• Helen decides that she wants to live with one of her daughters and moves to Arizona.
• Asher graduates from dental school and joins an existing practice in St. Louis.
• Mia marries, and she and her spouse move in with his parents.
• Using the insurance proceeds he received on Daniel's death, Logan pays off the mortgage on his personal residence.
Logan believes that these events may have an effect on his tax position for 2021. Therefore, he requests your advice.
Write a letter to Logan explaining in general terms the changes that will occur for tax purposes. Assume that Logan's salary and other factors not mentioned (e.g., property and state income taxes) will remain the same.
