Price per Square Foot, Explained
What price per square foot means, how to calculate it, why it varies so much, and the common mistakes people make when comparing homes with it.
Price per square foot is the most common shorthand in real estate. It's easy to calculate and easy to compare, which is exactly why it's so often misused. Here is what it measures, when it's useful, and when to ignore it.
How to calculate it
Divide the price by the home's finished living area. A home listed at $600,000 with 2,000 square feet of living space works out to $300 per square foot. In most listings, "square feet" means finished, heated living space. It usually excludes garages, unfinished basements, porches and decks, so check what's included before comparing.
Why it varies so much
The same rate can mean a bargain in one place and a splurge in another. Rates differ enormously between regions, between cities in the same region, and between neighborhoods in the same city. Within a neighborhood, rates still vary with condition, age, views, lot size and finishes. Treat any rate as local: compare it only with similar homes nearby.
The big trap: size
Smaller homes almost always have a higher price per square foot than larger ones in the same area. Every home needs a kitchen, bathrooms, a roof, a foundation and systems; those costs are spread over fewer square feet in a small home. That's why a tiny house can have a startling rate per square foot while still being one of the least expensive homes around, and why a large estate can show a modest rate despite a very high price.
Land is hiding in the number
Price per square foot divides the whole price, land included, by the size of the house. A modest cabin on a large lake lot or a small cottage on prized waterfront will show a very high rate, because you're really paying for the location. In expensive places, the rate tells you more about the land than the building.
Condition and character
A renovated home and a fixer-upper next door can differ by a wide margin per square foot. So can a historic home with original details and an ordinary one of the same size. Unusual homes (conversions, architect-designed homes, earth-sheltered or off-grid houses) often don't fit the local rate at all.
How to use it well
- Compare like with like: similar size, age, condition and location.
- Use it for a first estimate, then adjust (see how to estimate a home's value).
- Adjust down per square foot for very large homes, and up for very small ones.
- For homes with a lot of land or a special view, think about the land and the house separately.
Try it in the game
Every Market Match home lists its square footage. Pick a rate you think fits the town, multiply, and use the result as your first guess. Then let the color hints tell you how far off your rate was. It's a fun way to build intuition for how rates change from place to place. Play today's home.
