Javier and Anita Sanchez purchased a home on January 1, 2019, for $768,000 by paying $256,000 down and borrowing the remaining $512,000 with a 7 percent loan secured by the home. The loan requires interest-only payments for the first five years. The Sanchezes would itemize deductions even if they did not have any deductible interest. The Sanchezes marginal tax rate is 32 percent. (Round your intermediate calculations to the nearest whole dollar amount.)

a. What is the after-tax cost of the interest expense to the Sanchezes in 2019?

b. Assume the original facts, except that the Sanchezes rent a home and pay $35,840 in rent during the year. What is the after-tax cost of their rental payments in 2019?

c. Assuming the interest expense is their only itemized deduction for the year and that Javier and Anita file a joint return, have great eyesight, and are under 60 years of age, what is the after-tax cost of their 2019 interest expense?
