You wish to borrow $2,000,000 to finance the construction of a small multi-family investment property. A lender is willing to give you a 10 year fixed rate fully amortizing loan at 4.5%. In what month will you have paid back exactly half of your principal balance? Always round up to the nearest month, payments are always at discrete intervals (no payments will be made in the middle of any month). State your answer as a whole number.
(Hint: you want to find the N when the outstanding balance is 1M and subtract that from 120, your total number of scheduled payments)
