What is {primary_keyword}?
The {primary_keyword} is a tool used by appraisers, investors, and home sellers to estimate a property’s market value based on recent sales of similar properties, known as comparables. By adjusting for differences such as square footage, location, and condition, the {primary_keyword} provides a data‑driven estimate that reflects current market trends.
Anyone involved in real estate transactions—agents, buyers, sellers, or lenders—can benefit from a reliable {primary_keyword}. It helps set realistic asking prices, negotiate offers, and assess investment potential.
Common misconceptions include believing the {primary_keyword} gives an exact price or that it replaces a professional appraisal. In reality, it offers an informed estimate that should be complemented with expert insight.
{primary_keyword} Formula and Mathematical Explanation
The core formula adjusts each comparable’s sale price based on the square footage difference between the subject property and the comparable:
Adjusted Price = Sale Price + (Subject Sqft – Comparable Sqft) × Adjustment per Sqft
After calculating adjusted prices for all comparables, the average of these adjusted prices becomes the estimated market value.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Subject Sqft | Square footage of the property being evaluated | sqft | 500–5,000 |
| Sale Price | Recent transaction price of a comparable | currency | $50,000–$2,000,000 |
| Comparable Sqft | Square footage of the comparable property | sqft | 500–5,000 |
| Adjustment per Sqft | Value added/subtracted per square foot difference | currency/sqft | $20–$150 |
| Adjusted Price | Sale price after applying square footage adjustment | currency | — |
| Estimated Value | Average of all adjusted prices | currency | — |
Practical Examples (Real-World Use Cases)
Example 1
Subject property: 2,000 sqft.
Comparable 1: 1,900 sqft, $350,000 sale, $50/sqft adjustment.
Adjusted Price 1 = 350,000 + (2,000‑1,900)×50 = $355,000.
Comparable 2: 2,100 sqft, $360,000 sale, $45/sqft adjustment.
Adjusted Price 2 = 360,000 + (2,000‑2,100)×45 = $355,500.
Comparable 3: 1,800 sqft, $340,000 sale, $55/sqft adjustment.
Adjusted Price 3 = 340,000 + (2,000‑1,800)×55 = $351,000.
Average Adjusted Price = ($355,000+$355,500+$351,000)/3 = $353,833.
The {primary_keyword} estimates the subject property value at approximately $353,800.
Example 2
Subject property: 1,500 sqft.
Comparable 1: 1,400 sqft, $250,000 sale, $60/sqft.
Adjusted Price 1 = 250,000 + (1,500‑1,400)×60 = $256,000.
Comparable 2: 1,600 sqft, $260,000 sale, $55/sqft.
Adjusted Price 2 = 260,000 + (1,500‑1,600)×55 = $254,500.
Comparable 3: 1,450 sqft, $255,000 sale, $58/sqft.
Adjusted Price 3 = 255,000 + (1,500‑1,450)×58 = $258,900.
Average Adjusted Price = ($256,000+$254,500+$258,900)/3 = $256,467.
Thus, the {primary_keyword} suggests a market value of about $256,500.
