How factory-built homes could move the needle on affordability

Stacey Epperson first saw the possibility that manufactured housing held as a sustainable homeownership solution several years ago when working in a job that sent her to families in Appalachian Kentucky.

"Their manufactured homes were old. They were in bad repair, but they still owed money for them. They had loans on them. I thought that was a problem," she said.

"I thought a simple solution was to really do the home really well — really high quality — educate the consumer and get them into a good loan. Just kind of like normal housing," she said.  

"And maybe they wouldn't fall apart around them before they paid it off."

Her search for a solution eventually led to the launch of Next Step Networks, a Louisville, Kentucky-based nonprofit Epperson leads today as president and CEO. The organization aims to educate consumers and stakeholders in the housing and lending industries about prefabricated, factory-built homes while showcasing their potential as a viable source of affordable homeownership.   

Many in the housing industry, like Epperson, similarly think modern prefabricated constructions represent a prime opportunity to alleviate affordability and inventory challenges the U.S. is currently facing. But obstacles, ranging from manufactured housing's past reputation of poor quality to current zoning regulations, still stand in the way. 

With the U.S. experiencing a supply gap of between three to five million homes by most estimates, though, it won't come close to closing it without prefabricated construction, Epperson said. "It's got to be part of the solution." 

While manufactured units have been dogged in the past with the perception of shoddiness, often because of its early association with mobile homes, a window for growth is emerging as consumer sentiment shifts, thanks to improved design and construction standards. 

"I think the deficiencies of the old manufactured housing or mobile homes was — the code was very low. The standards were low. Those standards have gone up," Mike Loftin, CEO of Homewise, a New Mexico-based nonprofit enterprise helping state residents achieve homeownership.
Recent data shows a majority of consumers open to the idea of living in a manufactured home. In research conducted by Freddie Mac in 2022, approximately 62% of people said they would likely consider the purchase of prefabricated housing in the future, with the share skewing higher among younger populations. Whereas only 40% of baby boomers indicated they would entertain the thought of purchasing manufactured housing, the percentage grew to over 60% among all other age groups. 

In a sign of the expected role factory-built homes can play in creating more affordability, the Department of Housing and Urban Development actively boosted its support for the effort in 2023. In June, HUD introduced a new independent office of manufactured housing programs, which falls directly under the jurisdiction of Federal Housing Administration Commissioner Julia Gordon.

When manufactured homes are brought up today, increasingly, the conversation turns to modern modular designs, a major focus in Next Step's efforts to develop affordable opportunities. Built in individual rectangular modules at factories in compliance with local codes before being transported and assembled at the site location, interest in these homes is growing, in part because of their environmentally-friendly method of construction.

"There's incredible efficiencies you obtain inside an environmentally controlled setting. You don't have delays with workers and materials. You set jigs that can cut things precisely," said David Battany, executive vice president of capital markets at Guild Mortgage, in a panel at the 2023 Mortgage Bankers Association's Secondary Markets conference in May. 

Reduced labor costs also come into play, particularly in areas of the country where it is expensive to build, like the Bay Area or Seattle, Loftin said. "Building it off site, moving it 200 miles from an area where labor costs are a lot cheaper — there's some benefit there." 

Still, for consumers, some of the draw of modular construction today can come as much from the energy efficiency and design aesthetic of models that even allow for a small degree of customization. The emergence of startups, like Connect Homes in Los Angeles, is trying to grow the market and help change the image of factory-built units.  

"Prefab has come to mean maybe a little bit less 'trailer home' or 'mobile home,' and it's been sort of a term more associated with the architect-design stuff, which is sort of where we come from," said co-founder Gordon Stott. 

Trained as an architect, Stott helped launch the company in 2013. Connect Homes today operates an assembly-line operation in Southern California that can produce 2,000 square feet of housing in six days, he said. Along with single-family properties, Connect Homes produces accessory dwelling units and constructions to help serve homeless populations. 

"I think that really what we're able to show, just through pictures alone, is that what we're trying to do is provide people, architect-designed solutions at more affordable price points."
