3.2 Valuation and Appraisal
Key Takeaways
- The four characteristics that create value are remembered as DUST: Demand, Utility, Scarcity, and Transferability.
- The sales comparison approach is the primary method for residential homes; you adjust the COMPARABLES (never the subject) toward the subject property.
- The cost approach formula is: Land value + (Reproduction/Replacement cost - Depreciation) = Value; it best fits new or special-purpose buildings.
- Income approach value = Net Operating Income / Capitalization rate; GRM = sales price / gross rent applies to small residential rentals.
- A CMA and a BPO are NOT appraisals; only a licensed/certified appraiser performs an appraisal, governed by USPAP.
What Creates Value: DUST and Key Principles
Value is not the same as price or cost. Value is the worth of present and future benefits; price is what was actually paid; cost is the dollars to create the improvement. For a property to have value, four characteristics must be present — memorize them as DUST:
- Demand — desire to own backed by purchasing power.
- Utility — the property's usefulness for an intended purpose.
- Scarcity — limited supply relative to demand.
- Transferability — the ability to convey clear title.
Appraisers apply economic principles of value the exam tests directly:
| Principle | Meaning |
|---|---|
| Substitution | A buyer pays no more than the cost of an equally desirable substitute — the foundation of all three approaches |
| Highest and best use | The legally permitted, physically possible, financially feasible use that yields the greatest value |
| Conformity | Value is maximized when a property conforms to its neighborhood |
| Supply and demand | Prices rise when demand outpaces supply |
| Contribution | An improvement is worth what it ADDS to total value, not what it cost |
| Progression / Regression | A lesser home gains value near better ones; a better home loses value near lesser ones |
| Anticipation | Value reflects expected future benefits |
The Three Approaches to Value
Appraisers reconcile up to three independent approaches.
1. Sales Comparison (Market) Approach
The appraiser finds recently sold comparables ("comps") and adjusts their prices to the subject. The golden rule: adjust the comparables, never the subject. If a comp has a feature the subject lacks, subtract from the comp; if the comp lacks a feature the subject has, add to the comp. This is the primary method for single-family homes and rests on the principle of substitution.
2. Cost Approach
Used when comps are scarce — new construction, churches, schools, and other special-purpose properties. The formula is:
Land value + (Reproduction or Replacement cost − Depreciation) = Property value
Reproduction cost rebuilds an exact replica; replacement cost builds equivalent utility with modern materials. Depreciation here has three causes: physical deterioration (wear and tear), functional obsolescence (outdated design, e.g., one bathroom), and external (economic) obsolescence (off-site factors like a new highway). Physical and functional can be curable or incurable; external obsolescence is always incurable.
3. Income Approach
For income-producing property (apartments, offices, retail). Value = Net Operating Income (NOI) ÷ Capitalization rate. NOI is effective gross income minus operating expenses (debt service is NOT an operating expense). A lower cap rate signals lower risk and a higher value. For small residential rentals appraisers use the Gross Rent Multiplier: GRM = sales price ÷ monthly gross rent, then Value = GRM × subject's gross rent.
CMA vs. Appraisal vs. BPO, and USPAP
Real estate licensees regularly estimate value, but only one of these documents is a true appraisal.
| Tool | Who prepares it | What it is |
|---|---|---|
| CMA (Comparative Market Analysis) | Real estate licensee | An informal estimate of likely selling price from comps, used to set a listing price — not an appraisal |
| BPO (Broker Price Opinion) | Real estate broker | A value opinion often ordered by lenders for short sales/REO — not an appraisal |
| Appraisal | Licensed or certified appraiser | An independent, impartial, USPAP-compliant opinion of defined value as of a date |
A licensee giving a CMA or BPO must not represent it as an appraisal and generally may not charge a separate appraisal fee. Formal appraisals follow the Uniform Standards of Professional Appraisal Practice (USPAP), promulgated by the Appraisal Standards Board of The Appraisal Foundation and updated periodically. USPAP requires the appraiser to be independent, impartial, and objective, define the scope of work, and avoid any contingent-fee arrangement tied to a target value.
The final step of an appraisal is reconciliation — weighting the indicated values from the applicable approaches into a single supportable opinion (a simple average is improper).
The Appraisal Process and When It Is Required
Appraisers follow an orderly eight-step process: (1) state the problem and define the value sought; (2) determine the scope of work; (3) gather and analyze data — general (region, city, neighborhood) and specific (the subject and comps); (4) analyze highest and best use; (5) estimate land value; (6) apply the three approaches; (7) reconcile the indications; and (8) report the value. The standard product is the Uniform Residential Appraisal Report (URAR), used by lenders for most one-to-four-unit homes.
Federal law (the appraisal provisions arising from FIRREA) requires a state-licensed or certified appraiser for federally related transactions above a threshold; small loans below the threshold may use an evaluation instead. The type of value also matters: market value (most probable price in an arm's-length sale) differs from insurable value (replacement cost of improvements), assessed value (for taxes), and investment value (worth to a specific investor). Confusing these is a classic exam trap — a CMA estimates likely market price, not insurable or assessed value.
An appraiser is valuing a brand-new church with no comparable sales available. Which approach to value is most appropriate?
A comparable property has a swimming pool worth $20,000 that the subject property lacks. How should the appraiser handle this in the sales comparison approach?
A four-unit apartment building generates net operating income of $48,000 per year, and the market capitalization rate is 8%. Using the income approach, what is the indicated value?
A homeowner asks their listing agent to 'appraise' the house. The agent prepares a comparative market analysis (CMA). Which statement is correct?
