Understanding Comparable Sales (Comps)
Learn how appraisers and agents determine your home's value using comparable market analysis.
What Are Comparable Sales?
Comparable sales (or "comps") are recent sales of similar properties in your area. They're the foundation for determining your home's market value.
Key Criteria for Comps:
- Location: Same neighborhood or within 1–2 miles (location = 30% of value)
- Size: Similar square footage (within ±10%)
- Bedrooms & Bathrooms: Matching layout (bed/bath counts matter significantly)
- Age & Condition: Built around same year, similar condition
- Features: Pool, garage, lot size, updates, views
- Sale Date: Sold within last 3–6 months (older sales less relevant)
Appraisers typically use 3–5 comparable sales to estimate value. The goal is to find the "just right" matches that reflect your home's true market value.
How Comps Determine Price
Comp analysis uses adjustment methods to account for differences between your home and comparables.
Example Comp Analysis:
If your home is 5bd, 3ba, 2,500 sqft in same condition, it would appraise around $420,000–$430,000.
Finding & Analyzing Comps
You can research comps yourself or work with a real estate agent for professional analysis.
DIY Comp Resources:
- • Zillow, Realtor.com, Redfin: Search "sold homes" in your area
- • County Assessor's Office: Public property records & sale prices
- • MLS (through agent): Most accurate, real-time data
- • Appraiser Reports: If already obtained, review included comps
What to Look For:
- ✓ Days on market (fast sales = strong demand)
- ✓ Reason for sale (foreclosure/distressed ≠ normal market)
- ✓ Price per square foot (helps normalize size differences)
- ✓ Market trends (prices rising, falling, or stable?)
Why Agents & Appraisers Matter
Professional comp analysis is crucial for accurate pricing.
Real Estate Agent CMA (Comparative Market Analysis):
- • Access to MLS — most current, accurate data
- • Knowledge of local market trends & buyer preferences
- • Professional adjustments for condition & upgrades
- • Strategic pricing for faster sale & higher final price
Lender's Appraisal:
- • Independent, unbiased opinion of value
- • Required by buyer's lender to approve mortgage
- • Protects buyer from overpaying
- • If appraisal is low, sale price may need to be renegotiated
Pricing Strategy
Smart comp analysis leads to smart pricing decisions.
- ✓ Price at market: Attracts more buyers, faster sale
- ✓ Price slightly below market: Creates urgency, often generates multiple offers
- ✓ Overprice: Sits longer, fewer showings, eventual price reduction looks desperate
- ✓ Monitor the market: Adjust if comps change or market shifts
Homes priced within 10% of appraised value sell 40% faster and for closer to asking price.
