A new JPMorgan Chase report urges policymakers and housing stakeholders to look beyond mortgage rates and focus on how homes are built.
The report argues that modular, manufactured, and other factory-built housing methods could significantly lower construction costs and increase housing production, helping address one of the biggest obstacles facing today's mortgage market: a shortage of affordable inventory.
Released Tuesday by the JPMorganChase PolicyCenter, the report contends that innovative construction methods could reduce development costs by an estimated 20% to 30% while shortening construction timelines by 30% to 50% in certain projects.
For mortgage professionals, the findings arrive at a time when affordability remains one of the industry's most persistent challenges. While many market participants continue to focus on interest-rate movements, JPMorgan argues that increasing the supply of attainable housing may be equally important to expanding homeownership opportunities.
"Construction accounts for a significant share of home prices," the report notes, estimating that approximately 64% of a home's cost is attributable to construction-related expenses.
Beyond The Rate Conversation
The report is the latest indication that housing supply has become a central issue not only for builders and policymakers, but also for lenders seeking a recovery in purchase activity.
Even if mortgage rates decline, affordability challenges will likely persist if the market continues to face a shortage of entry-level and workforce housing. JPMorgan argues that innovative construction offers one potential pathway to bringing more attainable homes to market.
The report defines innovative construction as a range of approaches that shift portions of the building process into controlled factory environments. These include modular housing, manufactured housing, panelized construction, and other off-site building methods designed to improve efficiency and reduce costs.
According to JPMorgan, the U.S. homebuilding industry has been slower than many international markets in adopting factory-based construction techniques, despite growing evidence that such methods can accelerate housing production and improve affordability outcomes.
New Census Bureau data released last week showed construction activity on new single-family homes fell to an eight-month low in May, underscoring the challenges of increasing housing supply at a pace sufficient to meet demand. Against that backdrop, JPMorgan argues that more efficient construction methods could help lower costs and accelerate production.
Why It Matters To Lenders
While much of the report focuses on housing policy, several findings have direct implications for mortgage professionals.
One area highlighted by JPMorgan is the challenge of financing innovative construction projects. Manufacturers often require larger deposits earlier in the development process than traditional construction financing structures are designed to accommodate. Those differences can create friction for developers, lenders, and investors considering factory-built housing projects.
The report also stresses the importance of ensuring that lower-cost housing products remain compatible with conventional mortgage financing.
Among the examples cited is New York's MOVE-IN NY initiative, which supports manufactured housing designs that meet standards recognized by Fannie Mae and Freddie Mac, helping ensure buyers have access to traditional mortgage products.
JPMorgan also points to growing interest in CrossMod homes, a category of manufactured housing designed to qualify for GSE-backed financing while maintaining features more commonly associated with site-built homes. According to the report, some CrossMod projects have demonstrated construction costs roughly 30% lower than comparable site-built alternatives.
For lenders focused on first-time homebuyers, the ability to pair lower-cost housing with conventional financing could become increasingly important if affordability pressures remain elevated.
Regulatory Barriers Still Stand In The Way
Despite the potential benefits, JPMorgan argues that regulatory fragmentation continues to limit broader adoption.
The report identifies zoning restrictions, inconsistent building codes, permitting requirements, and inspection processes as some of the biggest barriers facing factory-built housing. These challenges often require manufacturers to modify designs across jurisdictions, reducing many of the efficiencies that make off-site construction attractive in the first place.
To address those obstacles, JPMorgan recommends that state and local governments create more uniform approval processes, expand incentives that support innovative construction, and invest in workforce development programs tailored to factory-built housing.
The report also notes that innovative construction could help alleviate labor shortages that have constrained housing production by creating more predictable, factory-based work environments that may attract new workers to the industry.
The Bigger Picture
For mortgage professionals, the report's broader message is clear: affordability is not solely a financing problem.
Lower mortgage rates can improve purchasing power, but they do not create housing inventory. As lenders continue searching for signs of a sustained purchase-market recovery, the availability of affordable homes may ultimately prove just as important as the direction of interest rates.
JPMorgan's report suggests that expanding housing supply through innovative construction methods could become an increasingly important part of that conversation — and one that lenders, policymakers, and housing stakeholders will likely be watching closely.
