Using the band of investment technique, calculate the overall capitalization rate given: mortgage at 70% LTV with 6% rate, and equity at 30% with 12% required return.
Correct Answer
B) 8.4%
Band of investment: (0.70 × 0.06) + (0.30 × 0.12) = 0.042 + 0.036 = 0.078 or 7.8%. Wait, let me recalculate: (0.70 × 0.06) + (0.30 × 0.12) = 4.2% + 3.6% = 7.8%. The answer should be 7.8%, but that's option a, not b.
Why This Is the Correct Answer
Option A (7.8%) is the correct answer based on the band of investment calculation. The formula is: (Loan-to-Value Ratio × Mortgage Rate) + (Equity Ratio × Equity Return Rate). Calculating: (0.70 × 0.06) + (0.30 × 0.12) = 0.042 + 0.036 = 0.078 or 7.8%. The explanation provided in the question confirms this calculation is correct but incorrectly states that B is the answer when the math clearly shows A is correct.
Why the Other Options Are Wrong
Option C: 9.0%
Option C (9.0%) is too high and would result from using incorrect rates or percentages in the calculation. This might occur if someone mistakenly used higher equity return requirements or different loan-to-value ratios than those specified in the problem.
Option D: 9.6%
Option D (9.6%) is significantly higher than the correct answer and would result from major calculation errors, such as adding the percentages incorrectly or using the wrong mathematical approach entirely. This could also result from confusing the band of investment technique with other capitalization rate derivation methods.
BLEND Method
B-L-E-N-D: Borrow percentage × Loan rate, Equity percentage × Equity rate, Numbers get multiplied, Decimals added together
How to use: When you see a band of investment problem, think BLEND: identify the two components (debt and equity), multiply each percentage by its rate, then add the results together to get your blended overall cap rate.
Exam Tip
Always double-check your decimal placement - convert percentages to decimals before multiplying, and remember that LTV + Equity ratio must equal 100%.
Common Mistakes to Avoid
- -Forgetting to convert percentages to decimals before calculating
- -Using the mortgage constant instead of the mortgage interest rate
- -Mixing up the loan-to-value ratio with the equity ratio

Analysis
The band of investment technique is a method for calculating the overall capitalization rate by weighting the cost of debt financing and the required return on equity based on their respective percentages of the total investment. This technique recognizes that most real estate investments are financed through a combination of mortgage debt and equity capital, each with different required rates of return. The overall cap rate represents the blended cost of capital that reflects the financing structure of a typical investor in the market. The calculation involves multiplying each component's percentage by its respective rate and summing the results.
Background Knowledge
The band of investment technique is one of several methods used to derive overall capitalization rates in real estate valuation, particularly useful when market data is limited. It assumes that the overall cap rate should reflect the weighted average cost of capital based on typical financing patterns in the market.
Real-World Application
Appraisers use this technique when comparable sales data is insufficient to extract market cap rates directly, or when analyzing investment properties where financing terms significantly impact value and investor behavior in the market.
