Jenny and Jerry have a home with a fair market value of $625,000. They borrowed $400,000 ten years ago to purchase the home (home value at that time was $450,000). They currently owe $250,000 on the acquisition loan. They recently borrowed $110,000 on a home-equity loan. The proceeds were used to purchase a car and take a vacation. What is the maximum amount of their indebtedness that can generate deductible interest in the current year?
