Key Takeaways
- Three approaches to value: sales comparison (comps), income (NOI/cap rate), and cost (land + building − depreciation).
- Cap Rate = NOI ÷ Value is the most important formula in income-producing real estate.
- Cross-reference at least two data sources; never rely on a single AVM.
- Valuation directly drives financing capacity, insurance, taxes, and investment returns.
This recap consolidates the core property valuation principles from Track 1. Review the three approaches to value, key formulas, data sources, and the connections between valuation and financial decisions.
Three Approaches Summary
The sales comparison approach uses recent comparable sales adjusted for differences—best for residential properties and active markets. The income approach converts property income to value via cap rates or DCF—best for income-producing properties. The cost approach estimates land value plus replacement cost minus depreciation—best for new or special-purpose properties. Professional appraisers reconcile multiple approaches using judgment-based weighting, not simple averaging.
| Approach | Key Principle | Best For | Weakness |
|---|---|---|---|
| Sales Comparison | Substitution | Residential, land, active markets | Requires comparable sales data |
| Income | Anticipation | Apartments, commercial, rental | Sensitive to cap rate assumptions |
| Cost | Substitution (construction) | New buildings, special purpose | Depreciation estimation is subjective |
Summary of the three approaches to value
Key Formulas Reference
The essential valuation formulas every investor should memorize: NOI = EGI − Operating Expenses. Cap Rate = NOI ÷ Value. Value = NOI ÷ Cap Rate. GRM = Price ÷ Annual Gross Rent. Band of Investment Cap Rate = (LTV × Mortgage Constant) + ((1 − LTV) × Equity Yield). LTV Loan Amount = min(Appraised Value, Purchase Price) × LTV Ratio.

Common Mistakes to Avoid
Treating the Property Valuation Principles topics as purely theoretical without applying them to actual markets.
Consequence: Knowledge without application does not improve investment outcomes.
Correction: Practice applying these frameworks to real properties and markets before making investment decisions.
Moving to advanced topics before mastering the foundational concepts covered in this track.
Consequence: Advanced analysis builds on fundamentals; gaps in foundation produce unreliable advanced results.
Correction: Ensure comfort with all core concepts before progressing to applied or advanced tracks.
