Frequently Asked Questions

Q

How does the extraction method estimate land value?

The extraction method calculates land value by subtracting the depreciated improvement value from the total property value. Formula: Land Value = Property Value − (Replacement Cost New − Accumulated Depreciation). For a $450,000 property with a $280,000 home that's 15 years into a 50-year life: depreciation = 30%, improvement value = $196,000, land = $254,000.

  • Step 1: Determine total property market value
  • Step 2: Estimate replacement cost new for improvements
  • Step 3: Calculate accumulated depreciation (age/useful life)
  • Step 4: Subtract depreciated improvement from total value
  • Result: Estimated land value by residual extraction

Q

What percentage of property value is typically land?

Land typically represents 20–40% of total property value in suburban areas, 50–80% in urban/coastal markets, and 10–20% in rural areas. Location is the main driver: land in San Francisco can be 70%+ of property value while land in rural Midwest may be under 15%.

  • Urban land is scarce → higher percentage of total value
  • Newer homes: lower land %, more value in the structure
  • Older homes: higher land %, structure has depreciated
  • Corner lots and large lots command premium land values
  • Zoning (residential vs commercial) affects land value significantly
Location TypeLand % of Property ValueExample ($500K Property)
Rural / farmland10–20%$50K–$100K
Suburban20–40%$100K–$200K
Urban40–60%$200K–$300K
Prime coastal/metro60–80%$300K–$400K
Q

What is replacement cost new in the extraction method?

Replacement cost new (RCN) is the current cost to build an equivalent structure from scratch. For residential properties, it's estimated at $100–$400 per sq ft depending on quality and location. A 2,000 sq ft home at $150/sq ft = $300,000 RCN. Use local construction cost data for accuracy.

  • RCN = Cost to build an identical structure today
  • Budget construction: $100–$150/sq ft
  • Average quality: $150–$250/sq ft
  • Custom/luxury: $250–$400+/sq ft
  • Include all attached improvements (garage, deck, pool)
  • Use Marshall & Swift or local contractor estimates

Average$150–$250$300,000–$500,000
Custom$250–$350$500,000–$700,000
Luxury$350–$500+$700,000+
Q

How is depreciation calculated for the extraction method?

Straight-line depreciation: Depreciation % = Age / Useful Life. Typical useful life for residential: 40–60 years. A 15-year-old home with 50-year useful life is 30% depreciated. Accumulated depreciation = RCN × 30% = dollar amount lost to age, wear, and obsolescence.

  • Straight-line: Age / Useful Life = Depreciation %
  • Residential useful life: 40–60 years typical
  • Well-maintained homes may have longer effective life
  • Poorly maintained homes depreciate faster
  • Major renovations can "reset" effective age

Q

Why is land value important for tax and investment purposes?

Land value matters because land cannot be depreciated for tax purposes — only improvements can. Higher land value means less tax depreciation available. For a rental property, only the improvement portion qualifies for the 27.5-year depreciation deduction. Land value also determines development potential.

  • IRS depreciation: Only improvements, not land, can be depreciated
  • Rental property: 27.5-year depreciation on improvement value only
  • Higher land % = less annual depreciation tax deduction
  • Insurance: Insure replacement cost of improvements, not land
  • Development: Land value signals redevelopment potential
  • Property tax appeals often focus on land vs improvement split

Inputs

Total Property Value$450,000
Replacement Cost New$280,000
Improvement Age15 years
Useful Life50 years

Result

Estimated Land Value$254,000
Land % of Property56.4%
Per Acre$1,016,000
Depreciation30%
Depreciated Improvement$196,000

Depreciation = 15/50 = 30%. Accumulated depreciation = $280,000 × 30% = $84,000. Depreciated improvement value = $280,000 − $84,000 = $196,000. Land value = $450,000 − $196,000 = $254,000 (56.4% of property value). Per acre = $254,000 / 0.25 = $1,016,000.

2$600,000 Property with 25-Year-Old Home on Half Acre

Inputs

Total Property Value$600,000
Replacement Cost New$350,000
Improvement Age25 years
Useful Life50 years
Lot Size0.50 acres

Result

Estimated Land Value$425,000
Land % of Property70.8%
Per Acre$850,000
Depreciation50%
Depreciated Improvement$175,000

Depreciation = 25/50 = 50%. Accumulated depreciation = $350,000 × 50% = $175,000. Depreciated improvement = $350,000 − $175,000 = $175,000. Land value = $600,000 − $175,000 = $425,000 (70.8% of property value). Per acre = $425,000 / 0.50 = $850,000.

Formulas Used

Extraction Method

Land Value = Property Value − (RCN − Accumulated Depreciation)

Estimates land value by subtracting the depreciated improvement value from total property value.

Where:

Property Value= Current total market value of the property
RCN= Replacement Cost New — cost to rebuild the structure today
Accumulated Depreciation= RCN × (Age / Useful Life)

Source: Appraisal Institute, The Appraisal of Real Estate

Straight-Line Depreciation

Depreciation = RCN × (Age / Useful Life)

Calculates the accumulated depreciation of improvements using the straight-line method.

Where:

RCN= Replacement cost new of the improvement
Age= Effective age of the improvement in years
Useful Life= Total expected useful life in years (typically 40–60)

Price Per Acre

Price/Acre = Land Value / Total Acres

Converts total land value into a per-acre rate for market comparison.

Where:

Land Value= Estimated land value from extraction method
Total Acres= Lot size in acres (1 acre = 43,560 sq ft)
