Sales Comparison Approach

The sales comparison approach estimates value by comparing the subject with recently sold, competitive properties and adjusting comparable sale prices for material differences. Adjust the comparable, not the subject: add when the comparable is inferior and subtract when it is superior. Reconcile the adjusted indications by reliability rather than blindly averaging them.

The Rule

PSI publishes the weight for the complete content area, not a fixed question count for this lesson. Learn the rule well enough to apply it when PSI changes names, numbers, or parties in a new scenario.

The lesson

These ideas work together. On the exam, the wrong answers usually describe a nearby concept, so learn where each one stops.

Comparable selection

Good comparables compete for the same buyers and are sufficiently similar in location, use, date, physical features, and transaction conditions.

Elements of comparison

Common adjustments address property rights, financing, conditions of sale, market conditions, location, physical characteristics, and economic characteristics.

Adjustment direction

If the comparable lacks a feature the subject has, add to the comparable's price. If the comparable has a superior feature, subtract.

Reconciliation

Give the most weight to sales requiring fewer and better-supported adjustments. The adjusted range communicates evidence quality.

Decision rule

Make the comparable look like the subject, using add for comparable inferiority and subtract for comparable superiority.

Georgia-specific distinction

The method is national, while comparable evidence must come from the subject's relevant Georgia market. A licensee's comparative market analysis supports brokerage advice but is not automatically an appraisal.

Worked example

Scenario. A comparable sold for $310,000 and lacks a garage that contributes $18,000 to the subject's market.

Reason it through. The comparable is inferior because it lacks the feature, so its sale price is adjusted upward.

Answer. The adjusted indication is $328,000.

Common exam traps

  • Adjusting the subject
  • Adding for a superior comparable
  • Using listing prices as closed sales without distinction
  • Averaging unreliable indications

Original practice questions with detailed explanations

These questions were written for instruction and mapped to the current outline. They are not copied from PSI or any live examination. Choose an answer before opening the explanation.

Question 1

A comparable sold for $300,000. It has a pool worth $20,000 that the subject lacks, and it lacks a garage worth $12,000 that the subject has. What is the comparable's adjusted price?

  1. A. $268,000
  2. B. $292,000
  3. C. $308,000
  4. D. $332,000
Show answer and explanation →

Answer: B. $292,000

Adjust the comparable to look like the subject: subtract $20,000 for the pool the subject lacks and add $12,000 for the garage the comparable lacks, giving $292,000. The $308,000 answer reverses both directions, which is the most common adjustment error.

Question 2

After adjustment, Comp A indicates $305,000 with two small adjustments, Comp B $318,000 with five large ones, and Comp C $296,000 with four. Which indication usually deserves the most weight?

  1. A. Comp B, because it is the highest
  2. B. The simple average of all three comparables
  3. C. Comp C, because it is the most conservative
  4. D. Comp A, because it needed the fewest adjustments
Show answer and explanation →

Answer: D. Comp A, because it needed the fewest adjustments

Reconciliation gives the most weight to the comparable that needed the fewest and best-supported adjustments, because it is most like the subject. A simple average treats a weak comparable the same as a strong one, which is why it is plausible but wrong.

Question 3

A licensee preparing a CMA finds a nearly identical house in the same subdivision listed at $340,000 that has not sold. How should it be used?

  1. A. As evidence of competition, not as a closed sale
  2. B. As the best comparable, since it is most similar
  3. C. As a closed sale adjusted for the asking price
  4. D. As proof of the subject's market value
Show answer and explanation →

Answer: A. As evidence of competition, not as a closed sale

Sales comparison rests on closed sales, and an active listing shows what a seller is asking, not what a buyer paid. It can show the competition the subject faces, but treating an asking price as a sale price overstates the evidence.

Ready to move on?

You are ready for the next lesson when all of these are true.

  • Explain Sales Comparison Approach in one clear answer without notes.
  • Separate Comparable selection from Elements of comparison using a fresh example.
  • Apply the decision rule to a new fact pattern and name the fact that controls the result.
  • State the Georgia-specific point or explain why the national rule applies unchanged.
  • Answer every practice question and explain the rule each rejected option misapplies.
  • Revisit this topic later in mixed practice without category labels.

Recommended next lesson

Continue with Cost Approach to Value. Next, the cost approach covers the method appraisers use when good comparable sales are scarce, as with new or special-purpose buildings: land value plus cost new minus accrued depreciation.

Sales Comparison Approach questions

Facts checked against the current PSI Candidate Information Bulletin and GREC sources. Editorial standards.

Is Sales Comparison Approach on the Georgia real estate exam?

Yes. It belongs to PSI's Valuation and Market Analysis content area, which is 8% of the 100-question national portion. PSI publishes content-area weights, not a guaranteed question count for this individual lesson.

What is the main rule for Sales Comparison Approach?

Make the comparable look like the subject, using add for comparable inferiority and subtract for comparable superiority.

What Georgia-specific distinction should I remember?

The method is national, while comparable evidence must come from the subject's relevant Georgia market. A licensee's comparative market analysis supports brokerage advice but is not automatically an appraisal.
