Builders have spent a decade cutting square footage to bring new homes within reach of increasingly stretched buyers. The strategy has produced smaller houses, but not the kind of cost relief that might be expected to come with them.
The average new single-family home sold in 2025 measured 2,409 square feet, down 11.6% from 2,724 square feet in 2015, according to a LendingTree analysis of U.S. Census Bureau data.
Over the same period, the average price per square foot climbed 71.9%, from $100.02 to $171.95.
That leaves builders trying to lower the total purchase price by offering less house while land, labor, materials, and other development costs continue to push the price of each square foot higher.
“Smaller homes can provide a more accessible entry point for buyers, but smaller doesn’t automatically mean affordable,” said Matt Schulz, LendingTree’s chief consumer finance analyst.
“A lower total price may reduce the down payment and monthly mortgage payment, but buyers may still pay a lot more for every square foot of living space.”
The findings add another layer to a difficult new-construction market. New-home sales fell 10.5% in July, leaving builders with a 9.6-month supply even as 63% offered sales incentives and 35% reduced prices in August.
Mortgage applications for newly built homes also declined 5.7% annually in July, suggesting that price reductions, closing-cost assistance, and mortgage-rate buydowns still are not enough to overcome buyers’ sensitivity to monthly payments.
Less House, Higher Cost
The shift toward smaller homes is visible beyond the national average.
One-quarter of new single-family homes sold in 2025 contained less than 1,800 square feet, up from 16% in 2015. Meanwhile, homes measuring at least 3,000 square feet dropped from 33% of sales to 20%.
The most common size range in 2025 was 1,800 to 2,399 square feet, accounting for 35% of new single-family homes sold. That was up from 28% a decade earlier.
“Paying nearly three-quarters more per square foot for a smaller home shows how much housing costs have risen,” Schulz said. “Buyers may spend less overall than they would on a larger home, but every square foot has become significantly more expensive.”
The comparison is based on nominal prices and is not adjusted for inflation. The Census Bureau’s price-per-square-foot measure also excludes the value of the land, meaning it does not capture the buyer’s complete cost or the considerable differences in land values among markets.
Still, the figures illustrate the limits of downsizing as an affordability strategy. A smaller footprint can reduce the total mortgage balance and ongoing expenses, but it does not eliminate the cost pressures built into new construction.
Smaller homes can be cheaper to heat, cool, furnish, maintain, and repair, Schulz said. But buyers also must consider whether a reduced floor plan, lot, or storage area will continue to meet their needs.
“Saving money today isn’t as valuable if you outgrow the home in just a few years,” he said.
A Sharp Regional Divide
The smaller-home trend has not played out evenly across the country.
The South, the nation’s largest new-construction region, recorded the steepest decline in average home size. Its average new home shrank 13.4% from 2,794 square feet in 2015 to 2,420 square feet in 2025.
Average sizes declined 12.2% in the Midwest and 9.2% in the West.
The Northeast was the only region where new homes became larger, increasing 1.1% to an average of 2,866 square feet. It also had the steepest rise in average price per square foot, which nearly doubled from $142.12 in 2015 to $280.23 in 2025.
“The Northeast is a bit of an outlier because land and construction costs are so high that builders often focus on larger, higher-end homes,” Schulz said. “The region may not be resisting the national trend because buyers want bigger homes, but because the economics of building make larger, higher-end projects a smarter move for builders.”
A lack of smaller new homes in high-cost Northeastern markets could leave first-time and moderate-income buyers with fewer new-construction options, while originators in the South and Midwest may encounter more borrowers comparing smaller new homes against older, larger properties.
The Midwest had the highest concentration of new homes under 1,800 square feet at 31%. The share was 28% in the West, 24% in the South, and 19% in the Northeast.
What Originators Should Compare
New homes can still carry a lower headline price than existing inventory. In July, the median new-home price was $403,800, or $46,500 below the median price of an existing single-family home. Builders also have more flexibility to offer rate buydowns, closing-cost assistance, and upgrades.
But the LendingTree findings show why the sticker price alone does not tell borrowers how much value they are receiving.
Originators working with new-construction buyers should compare the complete financing package, including the permanent note rate, the cost and duration of any buydown, lender fees, closing-cost credits, property taxes, homeowners insurance, lot size, upgrades, and expected maintenance expenses.
They should also determine whether the builder’s preferred-lender incentives outweigh the pricing and flexibility available through an outside lender.
“The real story isn’t just that homes are getting smaller,” Schulz said. “It’s that buyers are often making compromises on space without seeing the kind of price relief they’d hope for.”
For builders, smaller floor plans may help keep advertised prices from moving even further out of reach. For buyers and their originators, however, affordability increasingly requires measuring not only the monthly payment, but also how much house that payment actually buys.
