Loan Balances for Negative Amortization

You have a loan of $200,000.  The term is for 30 years, at 8% interest, all due and payable in 5 years.  Amortized payments would be $1,467.53 and interest only payments would be $1,333.33 ($200,000 X .08 = $16,000 divided by 12 = $1,333.33 monthly).  However, you want payments of $1,000 per month for the 5 years.  What is the balance due at the end of the 5th year?   Answer:  $224,492.29
