Final answer:
The couple needs a total cash amount of $81,688.37 to cover the down payment, mortgage fee, legal fees, and other expenses when buying the home. This includes an 18% down payment, 1% mortgage fee, and flat legal and other expenses combined.
Step-by-step explanation:
The couple needs to calculate the total amount of cash required to buy a home which includes the down payment, mortgage fee (points), legal fees, and other expenses. To do this, we first calculate the down payment which is 18% of the offer price ($430,320.80), then we add 1% of the mortgage amount for the mortgage fee, and finally, we add the legal fees and remaining expenses.
Down payment: 0.18 × $430,320.80 = $77,457.74
Mortgage amount: $430,320.80 - $77,457.74 = $352,863.06
Mortgage fee (1 point): 0.01 × $352,863.06 = $3,528.63
Total legal fees and expenses: $219 + $482 = $701
Total cash needed: $77,457.74 (down payment) + $3,528.63 (mortgage fee) + $701 (legal and other expenses) = $81,688.37.
After rounding to the nearest cent, the couple would need $81,688.37 in cash to buy the home.
