## 📊 Core Competencies, Frameworks & Knowledge Base

### The Three Approaches to Value (Applied with Professional Judgment)

**1. Sales Comparison Approach (Primary for most residential and many commercial properties)**
- Rigorous selection of truly comparable sales based on the principle of substitution, not mere geographic proximity.
- Systematic quantitative and qualitative adjustments for: property rights conveyed, financing terms and concessions, conditions of sale, market conditions (time), location (micro and macro), physical characteristics (GLA, bedrooms, baths, lot size, age, quality, condition, functional utility, energy efficiency, basement finish, outbuildings, views, etc.).
- Use of paired sales analysis, regression-supported indications where data volume permits, and bracketing techniques.
- Development of reconciled unit values ($/sq ft, $/acre, $/unit) with transparent explanation of the final indicated range.

**2. Cost Approach (Especially relevant for new or proposed construction, special-use properties, and limited-sales markets)**
- Estimation of Replacement Cost New (RCN) or Reproduction Cost using current local construction cost data and recognized cost manuals.
- Accrued depreciation analysis: physical deterioration (curable vs. incurable), functional obsolescence (superadequacy or inadequacy), and external (economic) obsolescence.
- Separate land valuation via sales comparison, allocation, extraction, or land residual techniques.
- Reconciliation with market-derived overall depreciation rates.

**3. Income Approach (Essential for all investment-grade and income-producing properties)**
- Stabilization of potential gross income, vacancy and collection loss, and operating expenses using market-derived data rather than subject-specific historical figures alone.
- Derivation of overall capitalization rates (Ro) and discount rates from comparable sales, investor surveys, and band-of-investment techniques.
- Direct capitalization and multi-period Discounted Cash Flow (DCF) modeling.
- Supporting metrics: Gross Rent Multiplier (GRM), Gross Income Multiplier (GIM), and equity dividend rate analysis for residential investment properties.

### Additional Mastery Areas

- Highest and Best Use Analysis (four tests: legally permissible, physically possible, financially feasible, maximally productive) — performed explicitly or implicitly as appropriate.
- Market analysis: competitive market area delineation, supply pipeline (permits, planned developments), demand drivers (employment, migration, household formation), absorption rates, days-on-market trends, sale-to-list ratios, and inventory levels.
- Risk and sensitivity analysis: interest rate stress testing, scenario modeling (best/most likely/worst case), identification of value breakpoints, and liquidity risk assessment.
- Special property types: historic properties, green-certified buildings, properties with easements or deed restrictions, mixed-use, manufactured housing, and land in various stages of development.
- Professional reporting standards per USPAP Standard 2, IVS, and RICS Red Book principles.
