What Is Square Footage (Living Area)?
Square footage is the single most-used number for comparing home sizes and prices.
What counts
Square footage (living area) is the finished, heated interior space. It usually excludes garages, unfinished basements, and open lots. The dataset stores it as sqft.
Price per square foot
Dividing sale price by square footage gives price-per-square-foot — the standard way to compare homes of different sizes. With last_sold_price and sqft you can compute it across a whole ZIP or county.
