Given:
buy a house in 9 years.
Estimated cost of the house = 175,800
down payment = 20%
closing cost = 7%
down payment:
175,800 x 20% = 35,160
closing cost:
175,800 x 7% = 12,306
Amount to save: 35,160 + 12,306 = 47,466
monthly savings:
9 years x 12 months = 108 months
47,466 / 108 = 439.50 savings per month.
