Hi Reader,
America's housing affordability crisis isn't only a story about who can afford to buy a home—it's increasingly a story about who can afford to keep one. According to Census Bureau data, roughly 20.7 million owner-occupied households—nearly a quarter of all homeowners—were burdened by housing costs in 2024, spending more than 30% of their income just to keep the lights on and the mortgage paid.
Much of that strain correlates to the age of the housing itself:
The median owner-occupied home in the U.S. is now 42 years old, up from just 31 in 2005, and nearly half of all owner-occupied homes were built in the 1980s or earlier.
Older homes come with older plumbing, older roofs, and older mechanical systems—and with them, the repair bills that too many first-time buyers fail to include in their budgets. That's the quieter half of the affordability crisis:
It isn't only about the price on the purchase agreement, but the decades of costs that follow it.
Mortgage payments, insurance premiums, energy consumption, maintenance, repairs, resilience to natural disasters, operating expenses—these are the costs that determine whether a home becomes an asset that builds wealth over time, or a financial quagmire that slowly drains it.
As construction costs, labor shortages, regulatory complexity, and insurance rates continue to rise, the industry is increasingly recognizing that making housing more attainable requires improving the entire lifecycle economics of a home—not just its purchase price.
That is precisely the challenge the Housing Innovation Alliance (HIA) has set out to address. Rather than treating innovation as the responsibility of individual companies or isolated research projects, HIA has created a collaborative ecosystem that brings together universities, production builders, manufacturers, architects, engineers, lenders, code officials, policymakers, and housing organizations to solve one of housing's most complex problems.
Through HIA’s inaugural Housing Innovation Challenge, universities become the homebuilding industry's research and development partners, developing and validating innovations that can move beyond prototypes and into neighborhoods where people can actually buy, finance, insure, and live in them—affordably.
Unlike traditional design competitions that reward visionary concepts, the Housing Innovation Challenge requires every finalist to construct a full-scale demonstration home. These homes must be permitted, financed, occupied, and monitored over time, transforming them into living laboratories that generate the performance data needed to reduce the risk of adopting new technologies.
The result is a powerful shift in how innovation occurs—from speculation to evidence, from theory to implementation, from proof to adoption.
In this week's feature, Purgula speaks with Bobby Vance, Co-Director of the Housing Innovation Challenge, about why universities are becoming the residential construction industry's R&D engine, how industrialized construction and digital twins are changing the economics and methods of homebuilding, and why measuring long-term performance may ultimately be the key to delivering homes that are not only less expensive to build, but significantly more affordable to own.
If successful, the Housing Innovation Challenge could become a model for accelerating innovation across the residential construction industry while helping make homeownership attainable for millions of future homeowners.
We've also included six articles that connect to different aspects of this week's story—from managing the costs of the home you already own, to what happens when a house is designed like a car or a computer, to what it takes for a new idea to prove itself before anyone will trust it.
The homes that pay off over time aren't the ones that look best on paper or stay entrenched in the ways of the past. They're the ones built with new methods, tested against real conditions, and proven—one measured result at a time.
