Answer: $1,495.92
Step-by-step explanation:
The amount you plan to borrow from the bank is:
= Cost of house - down payment
= 127,242 - 30,313
= $96,929
The amount to be paid is constant and so is an annuity. The loan amount is the present value of this annuity.
Term = 20 * 12 = 240 months
Interest = 18% / 12 = 1.5% monthly
Present value of annuity = Annuity * ( 1 - (1 + rate) ^-number of periods) / rate
96,929 = Annuity * (1 - (1 + 1.5%) ⁻²⁴⁰) / 1.5%
96,929 = Annuity * 64.79573209
Annuity = 96,929 / 64.79573209
= $1,495.92
