Valuation Methods and BPO
Appraisers estimate value using three primary approaches. The exam tests when each approach is most appropriate and how the calculations work.
Sales Comparison Approach (Market Data)
The sales comparison approach compares a subject property to recent comparable sales. It is the most common method for residential properties.
Key steps:
- Select comparable properties.
- Adjust for differences (size, condition, features, location).
- Reconcile adjusted prices to estimate value.
Principle of substitution supports this approach: buyers choose the best substitute available.
Adjustment Direction
- If a comp is better, subtract value to make it similar.
- If a comp is worse, add value to make it similar.
Cost Approach
The cost approach is based on the cost to replace the building minus depreciation, plus land value.
Formula:
Value = Land Value + (Replacement Cost - Depreciation)
Reproduction vs. Replacement
- Reproduction cost - Cost to build an exact replica.
- Replacement cost - Cost to build a similar structure with modern materials.
Depreciation Types
- Physical deterioration - Wear and tear (curable or incurable).
- Functional obsolescence - Outdated design or layout.
- External obsolescence - Negative influences outside the property.
The cost approach is useful for new construction and special-use properties where comparables are limited.
Income Approach
The income approach estimates value based on the income a property generates. It is most common for investment properties.
Key formulas:
- Net Operating Income (NOI) = Gross Income - Operating Expenses
- Value = NOI / Cap Rate
Gross Rent and Gross Income Multipliers
- GRM (Gross Rent Multiplier) - Price divided by monthly rent.
- GIM (Gross Income Multiplier) - Price divided by annual income.
These shortcuts are common on the exam for simple calculations.
CMA vs. BPO vs. Appraisal
Table: CMA vs. BPO vs. Appraisal
| Tool | Prepared By | Typical Use |
|---|---|---|
| Appraisal | Licensed appraiser | Lending, legal, and tax purposes |
| CMA | Real estate agent | Listing price and market guidance |
| BPO | Real estate broker | Lender or asset manager opinion |
A Broker Price Opinion (BPO) is an opinion of value prepared by a broker, often for lenders handling distressed properties. It is not a formal appraisal.

| BPO | Broker Price Opinion | Broker value opinion |
| CMA | Comparative Market Analysis | Agent pricing tool |
| GIM | Gross Income Multiplier | Income shortcut |
| GRM | Gross Rent Multiplier | Rent based valuation |
| NOI | Net Operating Income | Income minus expenses |
Assessed Value and Tax Implications
Assessed value is the value assigned for property tax purposes. Local governments use assessment ratios and mill rates to calculate taxes.
Basic formula:
Property Tax = Assessed Value x Tax Rate
Assessed value often lags market value because assessments may be updated on a cycle.
Applied Scenario: Which Approach Fits Best?
- A new custom home with few comparable sales: use the cost approach.
- A small apartment building: use the income approach.
- A typical single-family home in a subdivision: use the sales comparison approach.
Exam Traps
- Using the income approach for owner-occupied homes without rental income.
- Forgetting to subtract depreciation in the cost approach.
- Treating a CMA or BPO as a formal appraisal.
Summary
Sales comparison reflects market behavior, cost approach reflects replacement cost, and income approach reflects earning power. Know when each method applies, and recognize the limits of CMA and BPO.
Sales Comparison Adjustment Example
Suppose a subject property is 2,000 square feet with a 2-car garage. A comparable sale is 1,900 square feet and has a 1-car garage, and it sold for $390,000.
If square footage is valued at $100 per square foot and a garage bay is worth $8,000, the adjustments would be:
- Add $10,000 for 100 extra square feet
- Add $8,000 for the extra garage bay
Adjusted comp value = $390,000 + $10,000 + $8,000 = $408,000
This adjustment process is central to the sales comparison approach.
Cost and Income Examples
Cost Approach Example
Land value: $120,000 Replacement cost: $300,000 Depreciation: $40,000
Value = $120,000 + ($300,000 - $40,000) = $380,000
Income Approach Example
Gross annual income: $60,000 Operating expenses: $20,000 NOI = $40,000 Cap rate: 8 percent
Value = $40,000 / 0.08 = $500,000
Assessed Value Example
If assessed value is $350,000 and the tax rate is 1.2 percent, the annual property tax is: $350,000 x 0.012 = $4,200
These quick calculations appear frequently on the exam.
Selecting Comparables and Making Adjustments
Comparable sales should be recent, similar in size and condition, and located in the same market area. When exact matches do not exist, appraisers use adjustments based on paired sales or market-derived data.
Common adjustment categories include:
- Location and neighborhood
- Living area and lot size
- Bedrooms and bathrooms
- Condition and upgrades
- Parking and amenities
Remember the adjustment rule: adjust the comparable, not the subject.
Capitalization Rate Basics
The cap rate reflects the return an investor expects. A higher cap rate means higher risk and lower value, while a lower cap rate means lower risk and higher value. When interest rates rise, cap rates often rise, which can reduce values for income properties.
Exam Application Check
If the question asks which approach is least reliable for a unique property with no income and no comps, the best answer is usually the cost approach because it relies on replacement cost and depreciation.
