Suppose you borrow buy a $200000 hours, and put $50,000 down toward the purchase price. You borrow the rest from a bank at 6% annual interest, compounded monthly, on 1.1.16,for a 30-years period. The plan is that you pay on the last day of each month. And suppose immediately after making the sixth payment, you win a huge amount of money by betting against Mark. If you now can repay the bank in full, how much more must you pay, so that the bank gets its full future value?
