Tito Martinez has just arranged to purchase a $$600,000$ vacation home in the Bahamas with a $30$ percent down payment. The mortgage has an APR of $6\mathrm{.}6$ 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?
