Overview
Valuation and appraisal is a core topic on the NY Real Estate Salesperson Exam, covering how properties are professionally valued using standardized methods and principles. You will need to understand the difference between formal appraisals and informal estimates, the three approaches to value, the principles that drive real estate valuation, and how depreciation affects property worth. Expect several questions on this topic, particularly around the three appraisal approaches and adjustment logic.

Section 1: Appraisal Fundamentals
What Is an Appraisal?
An appraisal is a formal, objective, professional opinion of a property's value, typically required by lenders to ensure the loan amount does not exceed the property's worth. Appraisals are conducted by licensed or certified appraisers, not real estate salespersons.
Market Value vs. Market Price
| Term | Definition |
|---|---|
| Market Value | The estimated most probable price a property should sell for under ideal, fair conditions |
| Market Price | The actual amount paid in a specific transaction — may differ from market value |
• Market value assumes a competitive, open market, knowledgeable parties, and no duress
• Market price reflects what actually happened, including atypical circumstances
Regulatory Framework
• FIRREA (Financial Institutions Reform, Recovery, and Enforcement Act of 1989) — federal law that established appraisal standards and created the Appraisal Subcommittee to oversee state licensing of appraisers
• USPAP (Uniform Standards of Professional Appraisal Practice) — nationally recognized ethical and performance standards that all licensed appraisers must follow
CMA vs. Formal Appraisal
| Feature | CMA | Formal Appraisal |
|---|---|---|
| Performed by | Salesperson or broker | Licensed/certified appraiser |
| Purpose | Help price a listing | Lender requirement, legal matters |
| Legal standing | Informal estimate | Official, regulated opinion of value |
| USPAP required? | No | Yes |
Key Terms
• Appraisal — formal, regulated opinion of value
• FIRREA — federal law regulating appraiser qualifications
• USPAP — national ethical standards for appraisers
• CMA (Comparative Market Analysis) — informal estimate by a licensee
• Market Value — estimated worth under ideal conditions
• Market Price — actual transaction price
⚠️ Watch Out For
• A CMA is NOT an appraisal — salespersons perform CMAs; only licensed appraisers perform appraisals
• Market value ≠ market price — the exam frequently tests whether you know these can differ
• FIRREA is the federal law; know it by name and purpose

Section 2: Principles of Value
These economic principles explain why real estate values behave the way they do. Appraisers apply these principles when analyzing a property.
Core Principles Defined
#### Substitution
> A buyer will pay no more for a property than the cost of acquiring an equally desirable substitute.
• Foundation of all three appraisal approaches
• Buyers always have alternatives; value is capped by what comparable options cost
#### Contribution
> The value of a component is measured by how much it adds to the whole, not by its actual cost.
• Example: A pool costs $40,000 to install but may only add $20,000 in market value
• Critical for understanding renovation decisions
#### Conformity
> A property achieves maximum value when it is similar in size, style, and use to surrounding properties.
• Properties that deviate from neighborhood norms typically lose value
• Leads directly to the principles of regression and progression
#### Regression
> A higher-value property surrounded by lower-value properties will decrease in value.
• The superior property is "pulled down" by inferior neighbors
• Example: A $500,000 home in a neighborhood of $250,000 homes
#### Progression
> A lower-value property surrounded by higher-value properties will increase in value.
• The inferior property is "lifted up" by superior neighbors
• Example: A $250,000 home in a neighborhood of $500,000 homes
#### Anticipation
> Value is created by the expectation of future benefits.
• A property's present value reflects anticipated future income, utility, or amenities
• Basis for the Income Capitalization Approach
#### Highest and Best Use
> The most profitable, legally permissible, physically possible, and financially feasible use of a property that produces the greatest value.
• All four criteria must be met simultaneously
• Foundation upon which market value is based
• Must be analyzed for both the land as if vacant and the property as improved
#### Change
> Real estate values are constantly changing due to social, economic, governmental, and environmental forces.
• Appraisers must reflect current market conditions at the time of appraisal
• Past value does not guarantee future value
Key Terms
• Substitution — basis of all three approaches; no more than cost of equal alternative
• Contribution — value added to the whole, not cost of the part
• Conformity — similarity to neighborhood maximizes value
• Regression — superior property loses value among inferior neighbors
• Progression — inferior property gains value among superior neighbors
• Anticipation — present value reflects expected future benefits
• Highest and Best Use — most profitable, legal, physical, feasible use
• Change — forces constantly affect real estate values
⚠️ Watch Out For
• Regression vs. Progression — students frequently reverse these; remember: regression = going down, progression = going up
• Contribution is about value added to the whole, not the cost to install — a very common exam trap
• Highest and best use requires ALL FOUR criteria: legal, physical, financial feasibility, and maximum productivity
• Conformity drives both regression and progression — connect these concepts

Section 3: The Three Approaches to Value
Every appraisal considers up to three approaches. The appraiser selects the most appropriate method(s) based on the property type and available data, then reconciles the results into a final value opinion.
---
Approach 1: Sales Comparison Approach (Market Data Approach)
Best used for: Single-family residential properties, vacant land
Why: Abundant comparable sales data is usually available
#### How It Works
1. Identify comparable sales (comps) — recently sold properties similar to the subject
2. Make adjustments to comp sale prices for differences between the comp and subject
3. Reconcile adjusted prices into a value estimate for the subject property
#### The Adjustment Rule (Critical Exam Topic)
| Situation | Adjustment Direction |
|---|---|
| Comparable is superior to subject (has something subject lacks) | Subtract from comp price |
| Comparable is inferior to subject (lacks something subject has) | Add to comp price |
> 💡 Memory Trick: "CBS — Comparable Better, Subtract"
#### A Good Comparable Sale Should Be:
• Recent (typically within the past 6–12 months)
• Similar in location, size, age, condition, and features
• An arm's-length transaction (no relationship between buyer and seller)
Key Terms
• Sales Comparison Approach — value based on recent sales of similar properties
• Comparable Sale (Comp) — benchmark property used for comparison
• Adjustment — dollar amount added or subtracted to account for differences
• Arm's-length transaction — sale between unrelated, non-pressured parties
⚠️ Watch Out For
• The adjustment is made to the comparable's price, never to the subject
• If a comp has a garage and the subject doesn't, you subtract from the comp — this logic is frequently tested
• A CMA uses the same concept as the Sales Comparison Approach but is not a formal appraisal
---
Approach 2: Cost Approach
Best used for: New construction, special-use properties (schools, churches, hospitals), unique properties with few comps
Why: Most accurate when depreciation is minimal or when income data is unavailable
#### The Formula
```
Cost Approach Value =
Estimated Land Value
+ Cost to Reproduce or Replace Improvements
− Accrued Depreciation
= Indicated Value
```
> ⚠️ Land is never depreciated — only improvements (buildings) depreciate
#### Reproduction Cost vs. Replacement Cost
| Term | Definition |
|---|---|
| Reproduction Cost | Cost to build an exact replica using same materials and methods |
| Replacement Cost | Cost to build a structure of equal utility using current materials and standards |
• Replacement cost is more commonly used in practice — it's more realistic and avoids valuing obsolete features
Key Terms
• Cost Approach — value = land + improvements − depreciation
• Reproduction Cost — exact replica, same materials
• Replacement Cost — equal utility, current materials (preferred)
• Accrued Depreciation — total loss in value from all causes
⚠️ Watch Out For
• Land is NEVER depreciated — only buildings and improvements
• The Cost Approach is most reliable for new or special-use properties where depreciation is minimal
• Know the formula cold: Land Value + Replacement Cost − Depreciation
---
Approach 3: Income Capitalization Approach
Best used for: Commercial and investment properties (apartment buildings, office buildings, retail centers)
Why: Investors buy based on income potential; value is derived from what the property earns
#### Key Formula
```
Value = Net Operating Income (NOI) ÷ Capitalization Rate (Cap Rate)
Or rearranged:
Cap Rate = NOI ÷ Value
NOI = Value × Cap Rate
```
#### Understanding Cap Rate
• The cap rate is the expected rate of return on an investment property
• Higher cap rate = greater perceived risk = lower property value
• Lower cap rate = less perceived risk = higher property value
• Example: NOI of $50,000 ÷ 5% cap rate = $1,000,000 value
#### Gross Rent Multiplier (GRM) — Quick Method
```
GRM = Sale Price ÷ Gross Monthly (or Annual) Rent
Value = GRM × Subject Property's Gross Rent
```
• GRM is a simplified, quick estimation tool
• Uses gross rent (before expenses), not net income
• Less precise than full income capitalization
Key Terms
• Income Capitalization Approach — value based on income produced
• Net Operating Income (NOI) — income after operating expenses, before debt service
• Capitalization Rate (Cap Rate) — rate of return used to convert income to value
• Gross Rent Multiplier (GRM) — simplified income approach using gross rent
⚠️ Watch Out For
• Higher cap rate = lower value — this relationship is counterintuitive for many students
• GRM uses gross rent; full capitalization uses net operating income — know the difference
• The Income Approach is NOT typically used for single-family homes

Reconciliation of the Three Approaches
After completing all applicable approaches, the appraiser performs reconciliation — weighing the relevance and reliability of each approach to arrive at a final value opinion. This is not a simple average; it is a professional judgment.

Section 4: Depreciation & Property Value
Depreciation (also called accrued depreciation in appraisal) is the total loss in value from all causes. It is estimated and subtracted in the Cost Approach.
The Three Types of Depreciation
| Type | Cause | Curable? |
|---|---|---|
| Physical Deterioration | Wear and tear, deferred maintenance | Can be curable or incurable |
| Functional Obsolescence | Outdated or inadequate features within the property | Can be curable or incurable |
| External (Economic) Obsolescence | Negative forces outside the property | Always incurable |
#### Physical Deterioration
• Most common type
• Examples: roof needs replacement, peeling paint, aging HVAC
• Curable if cost to fix ≤ value added; incurable if not economically feasible
#### Functional Obsolescence
• Loss in value from features that no longer meet buyer expectations
• Deficiency examples (curable): outdated kitchen, only one bathroom in a multi-bedroom home
• Superadequacy examples (often incurable): over-improvement for the neighborhood (e.g., a marble ballroom in a modest home)
#### External (Economic) Obsolescence
• Caused by forces outside the property and beyond the owner's control
• Examples: proximity to landfill, freeway noise, neighborhood decline, factory nearby, adverse zoning changes
• Always considered incurable — the owner cannot fix an external problem
Curable vs. Incurable Depreciation
| Term | Definition |
|---|---|
| Curable | Economically feasible to fix; cost to repair ≤ value added |
| Incurable | Not cost-effective to correct; cost to repair > value added |
Key Terms
• Accrued Depreciation — total loss in value from all causes at the time of appraisal
• Physical Deterioration — wear and tear on the structure
• Functional Obsolescence — outdated features inside the property
• External Obsolescence — negative influences outside the property
• Curable Depreciation — economically feasible to fix
• Incurable Depreciation — not cost-effective to fix
⚠️ Watch Out For
• External obsolescence is ALWAYS incurable — the owner cannot control outside forces
• Do not confuse functional obsolescence (inside the property) with external obsolescence (outside forces)
• A superadequacy (over-improvement) is a form of functional obsolescence, not physical
• Depreciation is only applied in the Cost Approach — not in the Sales Comparison or Income Approach directly
