Question 1. A rectangular lot is 150 feet by 290.4 feet. How many acres is it?
- ① 4.4 acres
- ② 1 acre
- ③ 0.5 acre
- ④ 2 acres
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② 1 acre
Key point: Acres = square feet ÷ 43,560
- Area = 150 × 290.4 = 43,560 square feet.
- Acres = 43,560 ÷ 43,560 = 1 acre.
- Remember: 1 acre = 43,560 square feet.
Wrong choices
- 2 acres: 2 acres would be 87,120 square feet.
- 0.5 acre: 0.5 acre would be 21,780 square feet.
- 4.4 acres: This divides by 10,000 instead of 43,560.
Question 2. A home sells for $300,000. The commission rate is 6%. What is the total commission?
- ① $50,000
- ② $18,000
- ③ $1,800
- ④ $180,000
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② $18,000
Key point: Commission = price × rate
- Commission = Sale price × Rate.
- $300,000 × 0.06 = $18,000.
- Check: $18,000 ÷ $300,000 = 0.06.
Wrong choices
- $1,800: This moves the decimal one place too far.
- $180,000: This uses 60% instead of 6%.
- $50,000: This divides the price by 6 instead of multiplying by 6%.
Question 3. A salesperson's broker receives a 6% commission on a $250,000 sale. The salesperson gets 60% of the broker's share. How much does the salesperson earn?
- ① $9,000
- ② $15,000
- ③ $9,600
- ④ $6,000
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① $9,000
Key point: Total commission × agent's split
- Total commission = $250,000 × 0.06 = $15,000.
- Salesperson's share = $15,000 × 0.60 = $9,000.
- Check: broker keeps $15,000 − $9,000 = $6,000 (40%).
Wrong choices
- $15,000: $15,000 is the whole commission before the split.
- $6,000: $6,000 is the broker's 40% share.
- $9,600: This uses the wrong split amount.
Question 4. A buyer is getting a loan with an 80% loan-to-value ratio on a $350,000 home. What is the loan amount?
- ① $300,000
- ② $280,000
- ③ $70,000
- ④ $350,000
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② $280,000
Key point: Loan = value × LTV
- Loan = Price (or appraised value, if lower) × LTV.
- $350,000 × 0.80 = $280,000.
- Down payment = $350,000 − $280,000 = $70,000.
Wrong choices
- $70,000: $70,000 is the 20% down payment.
- $350,000: That is the full price, a 100% LTV.
- $300,000: This is not 80% of $350,000.
Question 5. A lender charges 2 discount points on a $200,000 loan. How much do the points cost?
- ① $2,000
- ② $40,000
- ③ $400
- ④ $4,000
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ $4,000
Key point: 1 point = 1% of the loan amount
- One discount point = 1% of the loan amount (not the price).
- 2 points = 2% × $200,000 = $4,000.
Wrong choices
- $400: This uses 0.2% instead of 2%.
- $40,000: This uses 20% instead of 2%.
- $2,000: This treats 2 points as 1%.
Question 6. A home's assessed value is $180,000. The tax rate is 25 mills. What is the annual property tax?
- ① $450
- ② $4,500
- ③ $7,200
- ④ $45,000
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② $4,500
Key point: 1 mill = $1 per $1,000 = 0.001
- 25 mills = 25 ÷ 1,000 = 0.025.
- Tax = $180,000 × 0.025 = $4,500.
- Check: $180,000 ÷ 1,000 × 25 = $4,500.
Wrong choices
- $450: This uses 2.5 mills by mistake.
- $45,000: This uses 25% instead of 25 mills.
- $7,200: This does not use the mill rate correctly.
Question 7. A seller wants to net $190,000 after paying a 5% commission. Ignoring other costs, what is the lowest sale price that will do this?
- ① $200,000
- ② $199,500
- ③ $209,000
- ④ $180,500
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ① $200,000
Key point: Price needed = desired net ÷ (1 − commission rate)
- The seller keeps 100% − 5% = 95% of the price.
- Price = $190,000 ÷ 0.95 = $200,000.
- Check: $200,000 − 5% ($10,000) = $190,000.
Wrong choices
- $199,500: This adds 5% of $190,000 instead of dividing by 0.95.
- $180,500: This subtracts 5% instead of adding it back.
- $209,000: This adds 10% instead of 5%.
Question 8. Annual property taxes of $3,650 are paid in arrears. Closing is on April 10, and the seller owns the day of closing. Using a 365-day year, what is the seller's share?
- ① $990 debit to the seller
- ② $2,650 debit to the seller
- ③ $1,000 credit to the seller
- ④ $1,000 debit to the seller
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ④ $1,000 debit to the seller
Key point: Arrears taxes → seller's days are a debit to seller, credit to buyer
- Daily tax = $3,650 ÷ 365 = $10 per day.
- Seller's days: Jan 31 + Feb 28 + Mar 31 + Apr 10 = 100 days.
- Seller's share = 100 × $10 = $1,000.
- The taxes have not been paid yet (arrears), so the seller owes this amount: debit seller, credit buyer.
Wrong choices
- $1,000 credit to the seller: Taxes paid in arrears are owed by the seller, so they are a debit to the seller.
- $2,650 debit to the seller: $2,650 is the buyer's share of the year.
- $990 debit to the seller: This leaves out the day of closing.
Question 9. A property earns $60,000 in effective gross income. Operating expenses are $15,000 and annual mortgage payments are $20,000. Using an 8% cap rate, what is the value?
- ① $750,000
- ② $562,500
- ③ $45,000
- ④ $312,500
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ② $562,500
Key point: NOI excludes mortgage payments; value = NOI ÷ cap rate
- NOI = $60,000 − $15,000 = $45,000 (mortgage payments are not subtracted).
- Value = $45,000 ÷ 0.08 = $562,500.
- Check: $562,500 × 0.08 = $45,000.
Wrong choices
- $312,500: This subtracts the mortgage payments, which are not operating expenses.
- $750,000: This uses gross income instead of NOI.
- $45,000: $45,000 is the NOI, not the value.
Question 10. An investor bought a property for $200,000 and sold it for $250,000. What was the percentage of profit based on the purchase price?
- ① 80%
- ② 50%
- ③ 25%
- ④ 20%
▼ Show answer and explanation▲ Hide answer and explanation
Answer: ③ 25%
Key point: Percent change = (new − old) ÷ old
- Profit = $250,000 − $200,000 = $50,000.
- Percent = $50,000 ÷ $200,000 = 0.25 = 25%.
Wrong choices
- 20%: 20% is the profit divided by the sale price, not the purchase price.
- 50%: This does not divide by the purchase price correctly.
- 80%: 80% is the purchase price as a percent of the sale price.
