Core Rules
1. Always State the Valuation Method
Every estimate must specify which approach:
- Comparable Sales (Comps): Based on recent similar sales
- Income Approach: Based on rental income (Cap Rate)
- Cost Approach: Land value + construction cost - depreciation
Most residential uses comps. Investment properties need income approach.
2. Require Key Property Data
Before estimating, gather:
- Location (address or neighborhood)
- Property type (SFH, condo, multi-family)
- Size (sqft or sqm)
- Bedrooms/bathrooms
- Condition (excellent/good/fair/poor)
- Year built
- Lot size (if applicable)
Missing data = wider value range.
3. Apply Adjustments Explicitly
When using comps, show adjustments:
| Factor | Adjustment |
|---|---|
| Extra bedroom | +3-5% |
| Extra bathroom | +2-3% |
| Newer by 10 years | +5-10% |
| Superior condition | +5-15% |
| Larger lot | +1-3% per 1000 sqft |
| Better location | +5-20% |
| Pool | +2-5% (climate dependent) |
Document each adjustment applied.
4. State Confidence Level
Every valuation includes confidence:
- High: 3+ recent comps within 0.5 miles, similar specs
- Medium: 2-3 comps, some adjustments needed
- Low: Limited data, significant adjustments, unusual property
5. Include Market Context
Current market conditions affect value:
- Seller's market: Values at high end of range
- Buyer's market: Values at low end
- Balanced: Use midpoint
Note days on market and inventory levels if known.
6. Cap Rate for Investment Properties
Income approach formula:
Property Value = Net Operating Income / Cap Rate
NOI = Gross Rent - Operating Expenses (typically 35-45% of rent)
Cap rates by property type (2024 averages):
- Multifamily: 5-7%
- Retail: 6-8%
- Office: 7-9%
- Industrial: 5-7%
Lower cap rate = higher value = lower risk.
7. Price Per Square Foot as Sanity Check
Always calculate and compare:
Price/SqFt = Property Value / Living Area
If result differs significantly from neighborhood average, explain why.
Common Traps
- Using old comps: Sales older than 6 months may not reflect current market. Prefer recent sales.
- Ignoring condition: Two identical homes can differ 20%+ based on updates and maintenance.
- Zillow/AVM over-reliance: Automated valuations miss condition, upgrades, and local factors. Use as starting point only.
- Not adjusting for differences: Raw comps without adjustments mislead. Always adjust.
- Confusing assessed value: Tax assessments often lag market value by 10-30%.
- Ignoring days on market: Homes that sat long may have sold below market.
Security & Privacy
Data that stays local:
- Property details and valuations in ~/property-valuation/
- No data sent externally
This skill does NOT:
- Access real-time MLS data (user must provide comps)
- Connect to Zillow/Redfin APIs
