Cost Approach to Value

The cost approach estimates value by adding land value to the depreciated cost of improvements. The basic formula is land value plus current replacement or reproduction cost new, minus accrued depreciation. It is often useful for newer or special-purpose properties when comparable sales or reliable income data are limited.

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.

Replacement and reproduction

Replacement cost creates equivalent utility with modern materials and standards. Reproduction cost creates a replica using the same design and materials as closely as possible.

Three depreciation categories

Physical deterioration concerns wear or damage. Functional obsolescence arises within the property. External obsolescence comes from outside the property.

Land value

Land is valued separately, commonly through market comparison, because appraisal depreciation applies to improvements rather than land itself.

Accrued depreciation

Accrued depreciation is total loss in value from all causes as of the effective date, not merely accounting depreciation or age.

Decision rule

Value land separately, estimate cost new, subtract all improvement depreciation, then add land.

Georgia-specific distinction

National cost concepts apply in Georgia. Local labor, material, site, and land-market data must support the figures used for an actual Georgia property.

Worked example

Scenario. Land is worth $90,000, replacement cost new is $360,000, and accrued depreciation is $75,000.

Reason it through. Depreciated improvement value is $360,000 minus $75,000, or $285,000. Add land value.

Answer. The cost-approach indication is $375,000.

Common exam traps

  • Depreciating land
  • Adding depreciation
  • Confusing reproduction with replacement
  • Using book depreciation as appraisal loss

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

Land is worth $80,000, replacement cost new of the house is $320,000, and accrued depreciation is $60,000. What value does the cost approach indicate?

  1. A. $260,000
  2. B. $340,000
  3. C. $180,000
  4. D. $460,000
Show answer and explanation →

Answer: B. $340,000

Subtract accrued depreciation from cost new, then add the land: $320,000 minus $60,000 is $260,000, plus $80,000 of land gives $340,000. Stopping at $260,000 leaves out the land, and $460,000 adds the depreciation instead of subtracting it.

Question 2

A four-bedroom house has only one bathroom, and buyers in the area pay less for it because of that layout. What type of depreciation is this?

  1. A. Physical deterioration
  2. B. External obsolescence
  3. C. Accounting depreciation
  4. D. Functional obsolescence
Show answer and explanation →

Answer: D. Functional obsolescence

Functional obsolescence is a loss in value from a problem within the property itself, such as a poor floor plan or too few bathrooms. External obsolescence comes from outside the property, like highway noise, so the mention of local buyers makes it plausible, but the cause here is the house's own layout.

Question 3

An appraiser values a 1920s courthouse by estimating the cost to build an exact replica with the same design and materials. Which cost is this?

  1. A. Reproduction cost
  2. B. Replacement cost
  3. C. Historical cost
  4. D. Assessed cost
Show answer and explanation →

Answer: A. Reproduction cost

Reproduction cost prices an exact replica using the same design and materials as closely as possible. Replacement cost prices equivalent utility with modern materials, so it is the wrong choice if you miss the words "exact replica" and "same materials."

Ready to move on?

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

  • Explain Cost Approach to Value in one clear answer without notes.
  • Separate Replacement and reproduction from Three depreciation categories 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 Income Approach and Market Analysis. Next, the income approach turns net operating income into value with a capitalization rate, the method appraisers lean on for investment property rather than the new or special-purpose buildings where the cost approach is most useful.

Cost Approach to Value questions

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

Is Cost Approach to Value 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 Cost Approach to Value?

Value land separately, estimate cost new, subtract all improvement depreciation, then add land.

What Georgia-specific distinction should I remember?

National cost concepts apply in Georgia. Local labor, material, site, and land-market data must support the figures used for an actual Georgia property.
