Comparative Market Analysis

A CMA estimates a property's market value by adjusting comparable recent sales to reflect differences with the subject property.

Method

1. Select 3 recent comparable sales near the subject property 2. Adjust each comp's sale price up or down for differences (e.g., extra bedroom, older roof) 3. Average the adjusted prices for an estimated market value

Adjustments

  • Positive adjustment: the comp is inferior to the subject, so adjust up
  • Negative adjustment: the comp is superior to the subject, so adjust down

    • 计算示例

    Three comparable homes sold for $380K, $395K, and $410K with adjustments of +2%, -3%, and 0% respectively.

    1. Comp 1 adjusted: $380,000 x 1.02 = $387,600
    2. Comp 2 adjusted: $395,000 x 0.97 = $383,150
    3. Comp 3 adjusted: $410,000 x 1.00 = $410,000
    4. Average: ($387,600 + $383,150 + $410,000) / 3 = $393,583
