Factory-Built vs. Site-Built Homes: Costs, Myths & Quality

  • The average factory-built home costs $126,800 — compared to a national average home sale price of $512,800. That’s a difference of nearly $386,000.
  • The same ENERGY STAR® certification that applies to site-built homes applies to factory-built homes, which means lower utility bills and a more comfortable place to live.
  • Factory-built homes can appreciate in value — just like any other home — when placed on owned land and financed with a real mortgage.
  • You have five mortgage options for a factory-built home today, including conventional loans and government-backed programs.

Shopping for a home means sorting through a lot of opinions. One you’ll probably hear: factory-built homes aren’t “real” homes. They don’t last, they don’t appreciate, and you can’t get a real mortgage on one.

That’s not what the data shows. Here’s an honest look at the numbers, and at what really determines a home’s quality and value.

According to the U.S. Census Bureau, the average new factory-built home was priced at $126,800 as of May 2025. The national average home sale price for site-built? $512,800. That’s a difference of nearly $386,000 — and it has nothing to do with quality.

That’s not a small difference, and it’s not because factory-built homes use cheaper materials or cut corners. Building in a factory means no weather delays, consistent work from start to finish, and the ability to buy materials in large cost-saving quantities. Those savings go directly to you, the buyer. Build time works the same way: a factory-built home can be ready in nine weeks or more, compared to six months or more for a site-built home.

Here’s something worth knowing: every manufactured home built in the United States has to meet the HUD Code — the federal standard covering structural strength, fire safety, plumbing, electrical, and energy efficiency. These aren’t voluntary guidelines. They’re the law, enforced through inspections at the factory before your home ever leaves.

Homes that go even further and earn the ENERGY STAR label, the same label you’ll find on energy-efficient appliances, have to beat minimum energy standards by at least 10%. An independent inspector verifies it. The result is a home that costs less to heat and cool, every month, for as long as you live there.

Every home delivered through Next Step® Network is ENERGY STAR-certified or solar-ready and placed on a permanent foundation. That means lower utility costs and a home that’s built to last — supporting sustainable homeownership for your family for years to come.

“Next Step Homes are designed with sustainability in mind. They’ve generated an impressive $49.5 million in lifetime household energy savings and eliminated 90,000 metric tons of carbon emissions,” said Stacey Epperson, president and CEO of Next Step. “This significant impact is equivalent to planting an incredible 1.5 million trees.”

This one gets repeated a lot. The data tells a different story.

A LendingTree study found that factory-built homes appreciated in value at the same rate as site-built homes from 2016 to 2021. An Urban Institute analysis of the Federal Housing Finance Agency’s Manufactured Housing Price Index confirms the same pattern.

What drives appreciation isn’t how a home was built — it’s whether you own the land it sits on and whether it’s financed with a real mortgage. When those two things are true, a factory-built home appreciates like any other home in your market. Here’s a real example: The Woody family in Western North Carolina bought a Clayton-built home and land for $179,500 in 2015. By July 2022, the property had grown in value to an estimated $315,000 — a gain of more than $135,000 in seven years.

Factory-built homes are built with the same materials you’d find in any site-built home: wood framing, drywall, insulation, name-brand appliances, and standard fixtures. The difference is that factory builders purchase those materials in large quantities across many facilities, which keeps costs down without touching quality. And because construction happens indoors, the work is consistent from start to finish.

You can — and you have options. Five distinct mortgage pathways are available to factory-built homebuyers today:

  • FHA Title II: A government-backed mortgage for manufactured homes on permanent foundations
  • Fannie Mae MH Advantage®: Conventional financing with appraisals comparable to site-built homes
  • Freddie Mac CHOICEHome®: Conventional financing for HUD Code homes with site-built features
  • USDA Section 502: Available in eligible rural areas for families with limited income
  • VA Loans: Available to eligible veterans and service members for manufactured homes on permanent foundations

Each of these is a real mortgage that builds equity, establishes ownership, and can help your home grow in value over time.

The quality of a home comes down to how it’s designed, what it’s built with, how efficiently it performs, and whether it builds value over time, not where the walls were assembled.

Factory-built homes can be ENERGY STAR-certified or solar-powered. They can sit on permanent foundations with real mortgages. They appreciate. They can be the foundation of your family’s financial future and a real path to homeownership.
