Question 4 (20 Marks) Each of the following independent cases involves interest payments and the issue is interest deductibility. Case A: Larry Lions borrowed $ 600,000 and used the funds to purchase an income producing property. Later, he sold the property for $450,000. He used the $450,000 to acquire two properties: property A cost $ 200,000 and property B cost $ 250,000. How will the $ 600,000 in borrowing be linked to the two properties? Case B: Joseph Jordan owned his home for many years and, over this period of time, had completely paid off the mortgage. Given the low interest rates that are available on mortgages, he negotiated a 10- year, $650,000 variable rate mortgage, with an interest rate of 3.2 %. Joseph Jordan then invested the entire $ 650,000 in publicly traded securities. Would the interest on the mortgage be deductible? Explain your conclusion.
