Delaware Real Estate Math
Practice Questions & Answers (2026)
Real estate math questions appear on every Delaware 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 Delaware Real Estate Commission does not provide a calculator — but the math is designed to be workable without one if you know the right formulas. Delaware 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.

Explanation
Total commission = $320,000 × 6% = $19,200. Selling office share = $19,200 ÷ 2 = $9,600. Salesperson's share = $9,600 × 40% = $3,840.

Explanation
Total transfer tax = $425,000 × 4% = $17,000. Split equally: $17,000 ÷ 2 = $8,500 per party. To solve this, multiply the relevant values: $425,000 at 4%.. The correct answer is $8,500.. This is a common calculation on the Delaware real estate exam.

Explanation
Area = Width × Depth = 150 × 200 = 30,000 square feet. Remember: 1 acre = 43,560 square feet. Multiply or divide as needed to convert between units.. The correct answer is 30,000 sq ft.. This is a common calculation on the Delaware real estate exam.

Total commission = $380,000 × 5.5% = $20,900. Listing broker's share = $20,900 ÷ 2 = $10,450. Listing salesperson's share = $10,450 × 60% = $6,270.

Value = NOI ÷ Cap Rate = $48,000 ÷ 0.08 = $600,000. To solve this, multiply the relevant values: $48,000 at 8%.. The correct answer is $600,000.. This is a common calculation on the Delaware real estate exam.
