You decide to buy a 60 unit apartment complex in Austin for $15,000,000. You have $6,000,000 to use as a down payment and have applied for a $9,000,000 mortgage loan from Bank of the Ozarks. The loan will have a 25 year term, be fully amortizing, and have fixed interest rate of 6.25% per annum. What is your monthly payment on the loan? (I think the answer is monthly payments of $59,370.24 but I could be wrong, the next part I'm lost on though)

If Bank of the Ozarks charges you a 2-point origination fee on the $9,000,000 loan described, what would the lenders yield be if you pay off the loan in 10 years (rounded to 2 decimal places)? What would the lender's yield be if it was paid in 18 months?
