Extending mortgage terms doesn't solve housing affordability because it primarily boosts demand for a fixed supply of homes. This drives asset prices higher, as sellers adjust prices to match buyers' new monthly payment capacity. The historical example of Japan's housing bubble, fueled by 100-year mortgages, illustrates this danger.

Current real estate deliveries were financed in the 2020-22 low-rate era, causing a temporary supply glut in high-demand sectors like Sunbelt apartments. Since new construction halted in 2023, today's depressed prices offer a unique entry point before supply normalizes and rents can accelerate.
Meaningful affordability cannot be achieved with superficial fixes. It requires long-term, structural solutions: building 5-10 million more homes to address housing costs (40% of CPI), implementing universal healthcare to lower medical expenses, expanding public higher education, and aggressive antitrust enforcement to foster competition.
The difference in home price trends between US regions is not about weather or jobs, but housing supply. States in the South and West that permit widespread new construction are seeing prices fall, while "Not In My Backyard" (NIMBY) states in the Northeast and Midwest face shortages and rising prices.
Housing scarcity is a bottom-up cycle where homeowners' financial incentive is to protect their property value (NIMBYism). They then vote for politicians who enact restrictive building policies, turning personal financial interests into systemic regulatory bottlenecks.
With high interest rates freezing the existing home market, homebuilders are successfully competing by using their own margins to "buy down" mortgage rates for customers. This strategy allows them to continue selling inventory even when affordability is broadly challenged.
While lower interest rates seem appealing, they often fuel intense market competition and bidding wars. Higher rates can thin the herd of buyers, providing an opportunity for those who can still afford to purchase to secure a deal with less pressure and more negotiating power.
The affordability crisis isn't solely about price inflation; it's also driven by "cultural inflation." The expected size of a starter home has ballooned from under 1,000 sq ft in the 1950s to nearly 2,500 sq ft today. This dramatic shift in consumer expectations fundamentally alters the affordability calculation.
A significant cause of today's housing inventory shortage is that homeowners are locked into low-interest mortgages. "Portable mortgages," which are being actively evaluated by the FHFA, would allow homeowners to transfer their existing mortgage to a new property, removing the financial disincentive to move and potentially unlocking market liquidity.
The American housing market is increasingly inaccessible to younger generations. The median age of a homebuyer has hit a record high of 59, the same age one can access retirement funds. Even the median first-time buyer is now 40, indicating a systemic affordability crisis.
Broad, non-means-tested stimulus programs, like the COVID CARES Act, function as the greatest intergenerational theft in history. They overwhelmingly benefit asset-owning incumbents by inflating housing and stock prices, while burdening younger generations with the debt used to finance the bailouts, effectively locking them out of asset ownership.
