Types of real estate comp calculators

There are several types of real estate comp calculators, each serving a specific purpose:

Calculator Type	Purpose	Key Features

Example calculation

Let's walk through an example calculation using a sales comparison calculator.

Subject property: 3-bedroom house, 2,000 sq ft, $400,000
Comparable 1: 3-bedroom house, 2,100 sq ft, $420,000
Comparable 2: 3-bedroom house, 1,900 sq ft, $390,000
Adjustment factor: 1.05 (for location premium)

Calculation: (($420,000 + $390,000) × 1.05) / 2 = $404,500

The estimated fair market value is $404,500, which is 1% higher than the subject property's asking price.
