CazaPrice per square foot, quickly
Price per square foot puts sales of different sizes on one scale. Divide each comp’s sale price by its square feet, take the median, and multiply by the subject home’s square feet. The median is steadier than the average when one sale is unusual.
Use comps of the same property type, nearby and sold recently. This tool does the arithmetic only. It does not adjust for condition, lot, age or date, so a rough range is the right way to read it.
Where to use it
The pull-comps guide shows how to find matching sales on Zillow. The low-offers guide uses sales to back a below-asking offer, and the price-cut guide shows how to read a cut against them.
The formula
Each comp: sale price ÷ square feet. Indicated price = median price per square foot × subject square feet.
The range uses the lowest and highest comp price per square foot times the subject’s square feet. The median is used because one unusual sale moves it less than the average.
Worked example
| Comp | Sale price | Sq ft | $/sq ft |
|---|---|---|---|
| 1 | $600,000 | 1,750 | $343 |
| 2 | $640,000 | 1,900 | $337 |
| 3 | $590,000 | 1,650 | $358 |
| 4 | $615,000 | 1,820 | $338 |
Median about $340.38 per sq ft × 1,800 sq ft = about $612,700. Range from the lowest to the highest comp: about $606,300 to $643,600. This is arithmetic only, not an appraisal: it does not adjust for condition, lot, age or sale date.
FAQ
How do you calculate price per square foot from comps?
Divide each comparable sale’s price by its square feet, take the median of those numbers, and multiply by the subject home’s square feet.
Why use the median instead of the average?
One unusual sale, such as a fully remodeled home, pulls the average much more than the median.
How many comps should I use?
Three to six close matches: same property type, similar size, nearby and sold recently. Three close matches beat ten loose ones.
Caza pulls nearby sales of the same property type and shows the median price per square foot on the listing.
