Ann is looking for a fully amortizing 30 year Fixed Rate Mortgage with monthly payments for $4,500,000. Mortgage A has a 4.38% interest rate and requires Ann to pay 1.5 points upfront. Mortgage B has a 6% interest rate and requires Ann to pay zero fees upfront. Assuming Ann makes payments for six months before she sells the house and pays the bank the balance, what is Anns annualized IRR from mortgage A? Write your answer as a percent rounded to two decimal points without the % sign (e.g. if you get 5.6499%, write 5.65).
