Property Value Estimation

This simplified comparable sales approach estimates property value using the average price per square foot of recently sold comparable homes, adjusted for condition.

Formula

Estimated Value = (Avg Comp $/Sq Ft x Subject Sq Ft) x (1 + Condition Adjustment%)

Notes

  • Gather at least 3 comparable sales within the past 6 months and 1 mile radius
  • Adjust for differences in condition, age, upgrades, and lot size
  • This provides a rough estimate; a professional appraisal is more precise
  • 计算示例

    Comparable homes sold at an average of $200 per sq ft. Your property is 2,000 sq ft in above-average condition (+5%).

    1. Base comparable value: $200 x 2,000 = $400,000
    2. Condition adjustment: $400,000 x 5% = $20,000
    3. Estimated property value: $400,000 + $20,000 = $420,000
