Quick Reference

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:

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
• Store sensitive financial information
