The Affordability Crisis
The US housing market has become one of the most politically charged economic issues of the decade. Home prices remain near all-time highs in most metropolitan areas, mortgage rates are elevated relative to the historic lows of the pandemic era, and the gap between housing costs and median household income has widened to its most extreme level since the 1980s.
For first-time homebuyers, the math has become nearly impossible in many markets. The combination of high prices and elevated mortgage rates has pushed monthly payments to levels that exclude a growing share of potential buyers, creating a generational divide in homeownership that carries significant political implications.
Supply Constraints
The fundamental driver of housing unaffordability is insufficient supply. Decades of underbuilding, restrictive zoning, and rising construction costs have created a structural deficit estimated at 3-5 million homes. This deficit cannot be closed quickly even under the most optimistic construction scenarios.
Key supply-side factors:
- Single-family housing starts remain below pre-2008 levels despite strong demand
- Labor shortages in the construction industry constrain building capacity
- Material costs have increased due to tariffs, supply chain disruptions, and energy prices
- Local zoning and permitting processes add significant time and cost to new development
- The Iran conflict has further elevated lumber, steel, and energy costs for builders
Mortgage Rate Scenarios
Mortgage rates are the most powerful short-term driver of housing market activity. The 30-year fixed rate has fluctuated in the 5.5-7.0% range, creating periods of market activity followed by freezes as rates spike.
The trajectory of mortgage rates depends directly on the Federal Reserve's policy path and inflation dynamics. If the Fed achieves a soft landing and gradually eases rates, 30-year mortgages could approach 5% by 2028, stimulating transaction volume. If inflation persists, rates could remain above 6%, extending the affordability crisis.
Price Correction Assessment
Our prediction market assigns a 22% probability to a nationwide housing price decline of 20% or more before 2028. This relatively low probability reflects the structural supply shortage that provides a floor under prices even in weak demand environments. A 20% decline would require a combination of recession, rising unemployment, and a significant increase in housing inventory — conditions that, while possible, represent a severe downside scenario.
Political Implications
Housing affordability will be a major campaign issue in both the 2026 midterms and the 2028 presidential election. Both parties are developing housing policy platforms, though the specifics differ. Democrats tend to emphasize subsidy programs and zoning reform, while Republicans focus on deregulation and supply-side incentives.
