Tito Martinez has just arranged to purchase a $$540,000$ vacation home in the Bahamas with a $30$ percent down payment. The mortgage has an APR of $6$ percent, compounded monthly, and calls for equal monthly payments over the next $30$ years. His first payment will be due one month from now. However, the mortgage has an eight year balloon payment, meaning that the balance of the loan must be paid off at the end of Year $8.$ There were no other transaction costs or finance charges. How much will the balloon payment be in eight years?
