What Is the Comparable Sales Approach?
The Comparable Sales Approach (also called the "Market Approach" or "Comps Method") values a property by comparing it to similar properties that have recently sold in the same area. It's the most widely used valuation method for residential property — and it's surprisingly straightforward once you know the steps.
How It Works: Step by Step
- Step 1: Find 3-5 comparable properties ("comps") that sold within the last 6-12 months in the same neighborhood.
- Step 2: Adjust for differences — size, condition, floor level, renovations, parking.
- Step 3: Calculate the average adjusted price per square foot.
- Step 4: Multiply by your target property's size to estimate its value.
A Malaysian Example
You're looking at a 1,000 sq ft condo in Bangsar South. Here are three recent sales:
| Comp | Size (sq ft) | Sale Price (RM) | Price/sq ft (RM) |
|---|---|---|---|
| Unit A — same floor, renovated | 1,050 | RM 630,000 | RM 600 |
| Unit B — lower floor, basic | 980 | RM 549,000 | RM 560 |
| Unit C — higher floor, partial reno | 1,020 | RM 591,600 | RM 580 |
Average price per sq ft: (RM 600 + RM 560 + RM 580) / 3 = RM 580/sq ft
Estimated value of your 1,000 sq ft unit: 1,000 x RM 580 = RM 580,000
If the asking price is RM 620,000, you know the seller is asking about 7% above the comparable market rate.
Adjustments Matter
No two properties are identical. You need to adjust comps for key differences:
- Renovated kitchen/bathroom: Add RM 20,000-50,000 (or $5,000-$12,000 for US properties)
- Higher floor with view: Add 2-5% premium
- No parking space: Deduct RM 30,000-80,000 depending on location
- Older building (10+ years): Deduct 5-10% for maintenance risk
