9.1 BASIC METHODS OF COMPARING SALES
Qualitative vs. Quantitative Adjustments
Direct Comparison Method has Limitations – Relies on “Intuition”, but a good cross-check 3

ELEMENTS OF COMPARISON METHOD
The Four Elements of Comparison• Terms and Conditions of Sale
•Date of Sale
• Location Elements
•Physical Elements
Detailed on the following slides 4

1. TERMS OF SALE
• Seller Financing• More Favorable than Third-Party Lender terms?• Unfavorable?
•Assumed Financing• Favorable or Unfavorable?
• Seller-Paid Points or Closing Costs• Generally, Buyer pays Points• In a Buyer’s Market, Seller may pay Points

1. CONDITIONS OF SALE (Con’t.)
• Property Rights Conveyed• Unusual Easements• Lease Terms – Favorable to Tenants?
•Motives of the Parties• Arm’s-Length• Adequate Market Exposure
• Personal Property/Tenant Improvements• Seller Concessions

ELEMENTS OF COMPARISON (Con’t.)
2. Date of Sale• Market Conditions Influence Price• Time of Sale vs. Date of Value
3. Location Elements• Desirability• Do Prices Differ Due to Location?
4. Physical Elements• Size, Quality, Conditions, Age, etc.• Specific Features / Degree of Modernization

COMPARING & ADJUSTING SALESComparison Process• Compare and Analyze the Four Elements of
Comparison• Are Feature Differences and Price Differences
Connected?
Adjustment Process• Are Market-Derived Adjustments Reasonable?• Should be Applied Consistently to Each Sale• Should Reduce Price Spread Between Sales

RULES FOR MAKING ADJUSTMENTS
Adjust the Sale to the Subject!Make the Sale to be More Like the Subject

RULES FOR ADJUSTMENTS (Con’t.)
Use Market-Derived Adjustments• Reflect the Market’s Reaction
Adjust in the Proper Sequence• From General to Specific• Terms & Conditions of Sale• Date of Sale• Location Elements• Physical Elements

9.3 SELECTING AND USING UNITS OF COMPARISON
Detailed on the following slides 13
Page 281
© 2015 OnCourse Learning
TYPES OF UNITS OF COMPARISON
Total Property• Prices for Similar Properties•Minor Differences Accounted for by
Ranking the Sales
Physical Units• Price per Square Foot or Acre• Price per Room• Price per Dwelling Unit (See Example 9.3)
14

UNITS OF COMPARISON TYPES (Con’t.)
Economic Units of Comparison• Price per Buildable Dwelling Unit• Price per Developable Building Area• Gross Income Multipliers
Applying Units of Comparison• Identify Why Unit Prices Differ• As Units (Size) Increases / Unit Price may Decrease

9.3 HOW TO ESTIMATE DOLLAR AND PERCENT ADJUSTMENTS
Direct Market Method•Matched Pair – At least Two Sales that can
be Compared to Estimate the Price Difference Caused by One Characteristic• Example 9.5 – Finding Adjustment for Size• Subject contains 2,600 SF Gross Living Area• Sale are Similar Except for GLA Size
See Next Slide 17
Page 293
© 2015 OnCourse Learning
EXAMPLE 9.5 - USING MATCHED PAIRS
Calculation For Size Adjustment
Adjustment: $10,000 ÷ 200 SF = $50 per SF
18
Page 295

Sale # Size (SF) Sale Price#2 2,700 $280,000#1 2,500 $270,000Difference 200 $10,000
DEPRECIATED COST METHOD
• Best Application is When Estimating an Adjustment for Physical Differences• Represents an Indirect Method, based in
part on Market Data• Example 9.7 - Finding a Garage Adjustment• Subject has a 440 SF Garage• Comparable Sale has No Garage• Problem – Finding Amount to Adjust the Sale
19

DEPRECIATED COST METHOD (Con’t.)
Cost New: 440 SF @ $43.50 = $19,140Less: Depreciation Cost New $19,140 Age is 60 Yrs. Life Expectancy 100 Yrs. Depreciation: 60 ÷ 100 = X 0.60 Equals: Depreciation in $ - 11,484Equals: Adjustment Amount for Garage: $ 7,656
Rounded: $ 7,700 20

STATISTICS - LINEAR REGRESSION
22
Page 300
© 2015 OnCourse Learning
STATISTICS – MULTIPLE REGRESSION• Can Analyze Multiple Variables, versus a
Single Variable (Linear Regression)• Requires a minimum of 20 to 30 sales
(properties)• Used by Assessors (Mass Appraisals) and
Lenders (Appraisal Reviews)• Now Used as a Valuation Tool and for
Supporting Adjustments by Appraisers• CompCruncher & Redstone are examples of
programs by Bradford Software 23

AUTOMATED VALUATION MODELS• Computer Software Programs (AVM)• Many use a form of Multiple Regression• Analyzes Data in Specified Area or Neighborhood• Relates Results of Database Search to Subject
Property Information Imputed into the Model (e.g. Zillow.com)
•When Applied to an Individual Property it is Not an Appraisal (without an Appraiser)• An AVM May Become the Basis for an
Appraisal (if Output is judged Reliable) 25

9.4 ARRIVING AT AN INDICATED VALUE
Four Steps to Arrive at a Conclusion1. Review the Entire Approach2. Review the Sales Data3. Estimate a Value Range4. Select a Final Value
(i.e. Reconciliation)
Detailed on the following slides26
Page 302
© 2015 OnCourse Learning
#1 – REVIEW THE ENTIRE APPROACH
•Comparability of Sales Selected•Activity Levels•Adjustment Accuracy• Statistical Limits• Lagging the Market•Motivation / Knowledgeable Parties
27
Page 302
© 2015 OnCourse Learning
#2 – REVIEW THE SALES DATA
• Sales Data• Consider Reliability of Information• Enough Information on Each Sale?• Look Back at Motivations – Particularly on one
Key and Important Sale
•Reviewing Adjustments• Consider Types of Adjustments / Reliability• Consider $ Amounts & Percentages (Net/Gross)
28

#3 – ESTIMATE A VALUE RANGE
•May not be Necessary if Data are quite Comparable and Range is Tight• Using the Range of Adjusted Sales Prices• Consider Upper and Lower Limits of Range• Range of Value from Most Comparable Sales• Do Indicators by Most Comparable Sales Cluster
in High or Low End of the Range?
29

#4 – SELECT A FINAL VALUE• Not a Mathematical Calculation – the Process
Requires Judgment!

CHAPTER SUMMARY
Analyzing and adjusting comparable sales rely on two main methods: the Direct Comparison Method and the Elements of Comparison Method.
The Direct Comparison Method simply compares the overall desirability of each sold property with that of the subject, without any quantitative adjustments.
31

CHAPTER SUMMARY (Con’t.)The Elements of Comparison Method compares the sales with reference to the details of four critical elements: the Terms and Conditions of Sale, the Time of Sale, the Location elements, and the Physical Elements of the properties.Arriving at a Value Conclusion requires a Review of the Entire Approach, a Review of the Sales Data, Estimating a Value Range, and the Selecting a Final Value. 32
