$179,200

**At 20%, the buyer's down payment was $160,000. Since each point is 1% of the $640,000 loan value ($800,000-$160,000), 3 points would be 3 x $6,400 = $19,200. Therefore the buyer's total downpayment costs are $179,200. $165,000

**The broker's 6% commission came to $7,200 (.06 x $120,000). Subtracted from the total commission of $9,000, it leaves an additional balance of $1,800. Since that portion was paid at the rate of 4%, $1,800 ÷ .04 = (home's second cost component) $45,000. Add that to $120,000 and the home's total selling price was $165,000.
