The total cost of the house is $234,500, and the buyer obtained a mortgage loan for $167,500. Therefore, the buyer's down payment will be:
Down payment = Total cost - Mortgage loan
Down payment = $234,500 - $167,500
Down payment = $67,000
The buyer has already paid $2,000 as earnest money, so the remaining cash required at closing will be:
Cash required = Down payment + Closing costs - Earnest money - Prorated taxes
Cash required = $67,000 + $2,250 + $1,850 - $2,000 - $4,880.96
Cash required = $63,219.04
Therefore, the buyer must bring $63,219.04 in cash to the closing.
