Answer:
$ 637.5
Explanation:
The listed value = $ 200000
the seller accept an offer of 90 % = 0.9 × 200000 = $ 180000
the house was appraised for $ 185000 and lenders always prefer to use the lesser value
the buyer obtained a loan of 85% = 0.85 × 180000 = $ 153000
amount paid per year = $ 153000 × 0.05 = $ 7650
first month payment = 7650 / 12 = $ 637.5
