Connecticut Real Estate Math
Practice Questions & Answers (2026)
Real estate math questions appear on every Connecticut real estate exam and test a focused set of calculations: commission splits, prorations (property tax, rent, interest), loan-to-value ratios, appreciation and depreciation, and area calculations. The Connecticut Real Estate Commission does not provide a calculator — but the math is designed to be workable without one if you know the right formulas. Connecticut candidates consistently lose points on proration questions because they apply the wrong day-count convention (360-day vs. 365-day year) or miscalculate the seller's vs. buyer's share. Work through every problem in this section until you can solve each type without hesitation.

Q1. A Connecticut property is listed at $425,000. The seller agrees to pay a 5.5% commission. What is the total commission paid at closing?
Explanation
Commission = $425,000 × 5.5% = $425,000 × 0.055 = $23,375.
Q2. A buyer takes out a $280,000 mortgage at 6.5% annual interest. What is the first month's interest charge?
Explanation
Monthly interest = Loan balance × (Annual rate ÷ 12) = $280,000 × (6.5% ÷ 12) = $280,000 × 0.005417 = $1,516.67.
Q3. A Connecticut property has an assessed value of $240,000 and the tax rate is 28.5 mills. What is the annual property tax?
Explanation
Property tax = Assessed value × Mill rate. $240,000 × 28.5 mills = $240,000 × 0.0285 = $6,840.
Q4. A property sells for $510,000. The seller paid $390,000 three years ago. What is the seller's percentage gain on the original purchase price?
Explanation
Gain = $510,000 − $390,000 = $120,000. Percentage gain = ($120,000 ÷ $390,000) × 100 = 30.77%, approximately 30.8%.
Q5. A Connecticut broker receives a 6% commission on a $450,000 sale. The commission is split 50/50 with the buyer's broker. The listing broker then splits their half 60/40 with the listing salesperson. How much does the listing salesperson earn?
Explanation
Total commission = $450,000 × 6% = $27,000. Listing broker's half = $13,500. Listing salesperson's share = $13,500 × 40% = $5,400. Wait — recalculating: $13,500 × 60% = $8,100. The salesperson gets 60% = $8,100.
Q6. A Connecticut property is assessed at 70% of its market value. If the assessed value is $210,000, what is the market value?
Explanation
Assessed Value = Market Value × Assessment Ratio. $210,000 = Market Value × 0.70. Market Value = $210,000 ÷ 0.70 = $300,000.
Q7. A buyer purchases a Connecticut property for $325,000 and puts 20% down. What is the loan amount?
Explanation
Down payment = $325,000 × 20% = $65,000. Loan amount = $325,000 − $65,000 = $260,000.
Q8. A rectangular lot in Connecticut measures 150 feet by 200 feet. What is the lot's area in acres? (1 acre = 43,560 sq ft)
Explanation
Area = 150 × 200 = 30,000 sq ft. Acres = 30,000 ÷ 43,560 = 0.689 acres, approximately 0.69 acres.
Q9. A Connecticut seller nets $280,000 after paying a 5% commission. What was the selling price?
Explanation
Net = Selling Price × (1 − commission rate). $280,000 = Selling Price × 0.95. Selling Price = $280,000 ÷ 0.95 = $294,736.84, approximately $294,737.
Q10. Annual property taxes on a Connecticut home are $7,200. At closing on April 1, the buyer takes possession. The seller paid the full year's taxes. How much does the buyer owe the seller at closing for tax proration (using a 360-day year, 30-day months)?
Explanation
Taxes cover Jan 1–Dec 31. Seller owns Jan 1–Mar 31 = 90 days. Buyer owns Apr 1–Dec 31 = 270 days. Buyer owes seller for 270 days: $7,200 ÷ 360 × 270 = $20 × 270 = $5,400.
Q11. A Connecticut investment property generates monthly rents of $3,500. Using a GRM of 130, what is the estimated value?
