Ch7. Appraising Improved Properties — Land-Building Allocation and Reconciliation

Improved Property — Definition

Improved Property: Real estate consisting of land together with permanent structures, site improvements, or other enhancements that add to the site’s utility or value.

Appraisal framework options:
① Separate valuation:  Value land + improvements independently, then sum
② Unit valuation:      Value the entire property as a single economic unit

Standard practice:
- The three approaches (Cost, Sales Comparison, Income) each produce
  a single indication of total property value
- Land is separately identified within the Cost Approach
- Income and Sales Comparison typically value the combined property

When unit (going-concern) valuation is appropriate:
- Properties where land and improvements function as an indivisible economic unit
  (e.g., hotels, golf courses, large industrial complexes)
- Special-purpose properties where individual components have no independent market

Separating Land and Building Value

Total Property Value = Land Value + Building (Improvement) Value

Land Value:
- Estimated by the Sales Comparison Approach using vacant-land comps
- Valued at Highest and Best Use as though vacant
- Unaffected by the existing improvements' quality or condition

Building Value:
- Primary: Cost Approach (depreciated cost)
- Supporting: Sales Comparison, Income Approach

Important: HBU as vacant may differ from HBU as improved.
→ If existing improvements do not represent HBU as vacant,
  the buildings suffer economic (external) obsolescence
→ The shortfall is reflected in the Cost Approach as additional depreciation

Reconciliation of Value Indications

After applying all three approaches, the appraiser reconciles the separate indications into a single final value conclusion.

Reconciliation (not mechanical averaging):
Cost Approach Indication:            $X
Sales Comparison Indication:         $Y
Income Approach Indication:          $Z

→ Weighted judgment, not arithmetic average

Factors guiding reconciliation:
① Assignment purpose (mortgage, insurance, litigation, estate, etc.)
② Property type and typical investor behavior
   - Income properties: Income Approach weighted most heavily
   - Special-purpose buildings: Cost Approach weighted most heavily
   - Residential: Sales Comparison weighted most heavily
③ Data reliability and quantity for each approach
④ Current market conditions (buyer/seller market, liquidity)

Example: Leased office building
- Cost Approach:            $7,500,000
- Sales Comparison:         $8,100,000
- Income Approach:          $7,750,000
→ Income Approach primary; Sales Comparison supporting
→ Final Value Conclusion: $7,900,000

Land and Building Allocation Techniques

When a single lump-sum value indication must be split between land and improvements (e.g., for tax assessment, insurance, or investment analysis):

Land Residual Technique

Land Value = (Total NOI − Return on Building) / Land Cap Rate

Step 1: Estimate building value by Cost Approach
Step 2: Calculate return on building = Building Value × Building Cap Rate
Step 3: Residual income = Total NOI − Return on Building
Step 4: Capitalize residual income at Land Cap Rate

Example:
Total NOI:               $80,000
Building Value (Cost):  $500,000
Building Cap Rate:       7%
Land Cap Rate:           5%

Return on Building = $500,000 × 7% = $35,000
Land Residual Income = $80,000 − $35,000 = $45,000
Land Value = $45,000 / 5% = $900,000

Building Residual Technique

Building Value = (Total NOI − Return on Land) / Building Cap Rate

Used when land value is more reliably known than building value.

Ratio / Allocation Method

Apply a typical land-to-total-value ratio from market evidence:
Example: If comparable improved properties show land = 35% of total value,
         and total appraised value = $1,200,000,
         then Land = $420,000 and Building = $780,000

Appraisal Purpose and Approach Emphasis

Mortgage / Collateral Appraisal:
- Conservative market value orientation
- Sales Comparison primary; Cost and Income supporting
- Appraiser must address marketability and exposure time

Eminent Domain / Condemnation Appraisal:
- Valued as of the "date of taking"
- No enhancement from the project itself included
- All three approaches considered; market value standard

Litigation / Dispute Appraisal:
- Market value standard under applicable law
- Highest reliability of data and methodology required
- Opposing expert scrutiny anticipated

Insurance / Replacement Cost:
- Cost Approach primary (replacement cost new basis)
- Land typically excluded from insurable value

Estate / Tax Appraisal:
- IRS-compliant definition of fair market value (Revenue Ruling 59-60)
- Sales Comparison primary for residential; Income primary for commercial

Reconciliation vs. Averaging ★★★★★ : Reconciliation is a reasoned, judgment-based weighing of approach indications — not an arithmetic average. The appraiser explains why one approach is given more weight than another. Memory trigger: Reconcile = weigh by relevance, not average

Separate vs. Unit Valuation ★★★★★ : Standard practice values land and improvements separately within the Cost Approach. Unit (going-concern) valuation is used only when components are economically inseparable. Memory trigger: Separate = standard; Unit = going-concern exception

Land Residual Technique ★★★★☆ : When total NOI and building value are known, land is “what’s left” after compensating the building. Requires reliable building value and cap rates. Memory trigger: Land = (Total NOI − Building Return) ÷ Land Cap Rate

Practice Quiz

Q. An income-producing warehouse shows Cost Approach = $3,200,000; Sales Comparison =$ 3,500,000; Income Approach = $3,400,000. How should the appraiser reconcile?

The Income Approach deserves the most weight for an income-producing property — investors price the asset based on its cash flow potential. Sales Comparison provides a useful check. Cost Approach is least relevant for an older income property where depreciation estimates are judgmental. A reasonable final conclusion might be in the $3,400,000–$ 3,450,000 range.

Q. Why might existing improvements contribute to economic obsolescence in a Cost Approach?

If the existing improvements do not represent the HBU as vacant (e.g., a small retail strip on a site zoned for a high-rise office), the existing use under-utilizes the site. The surplus land or mismatched improvement causes external/economic obsolescence that is measured as an additional depreciation deduction in the Cost Approach.
