ANSWER KEY
1. b) $2,700
How to do it: 50 acres × $900 per acre = $45,000 total sale price; $45,000 sale price × .10 commission = $4,500 total commission; $4,500 × .60 broker’s share = $2,700 broker’s commission
2. a) .06 or 6 percent
How to do it: $3,120 commission ÷ $52,000 sale price = .06 rate or 6 percent
3. b) $150
How to do it: $.60 ÷ $100 = .006 premium rate; .006 × $25,000 policy = $150 premium
4. c) 45
How to do it: 43,560 square feet per acre × 12 acres = 522,720 total square feet – 126,720 square feet for streets, sidewalks, etc. = 396,000 available square feet; 80 feet × 110 feet = 8,800 square feet per lot; 396,000 available square feet ÷ 8,800 = 45 lots
5. b) $346.10
How to do it: $780 ÷ 12 months = $65.00 taxes per month; $198 per year ÷ 12 months = $16.50; $264.60 principal and interest payment + $65.00 + $16.50 = $346.10
6. d) $25,860
How to do it: .12 net return × $215,500 purchase price = $25,860 net income
7. c) $4,334
How to do it: $98,500 sale price × .08 commission rate = $7,880 total commission; $7,880 total commission × .55 sales associate’s share = $4,334 commission due sales associate
8. c) $20,980
How to do it: $139,900 sale price × .80 = $111,920 loan; $139,900 sale price – $111,920 loan = $27,980 down payment; $27,980 – $7,000 earnest money deposit = $20,980
9. d) Six months
How to do it: $85,000 loan × .075 interest rate = $6,375 interest per year; $6,375 interest ÷ 12 months = $531.25 per month; $3,187.50 ÷ $531.25 = 6 months
10. d) $59,239
How to do it: $52,000 sale proceeds + $2,500 settlement costs = $54,500; $54,500 ÷ .92 = $59,239.13 or $59,239 sale price
11. c. $32,375
How to do it: $129,500 sale price × .75 LTV = $97,125 loan; $129,500 sale price – $97,125 loan = $32,375 down payment
12. c) $3,137.50
How to do it: $125,500 × .025 property tax rate = $3,137.50
13. a) $1,950
How to do it: $40.00 × .75 homeowner’s share = $30.00 homeowner’s cost per foot of frontage; $30.00 × 130 feet of footage = $3,900 ÷ 2 = $1,950
14. d) 100
How to do it: 640 acres ÷ 4 ÷ 2 = 80 acres; 640 acres ÷ 4 ÷ 4 ÷ 2 = 20 acres; 80 + 20 = 100 acres
15. c) $665 debit to seller, $665 credit to buyer
How to do it: $950 ÷ 30 days = $31.666667/day; $31.666667 × 21 days = $665.00; Seller has collected the rent in advance; Seller owes buyer; Debit seller and credit buyer
