Mortgages Consume 36% of US Family Income

Mortgages now consume 36% of the median U.S. family's income, a significant increase that challenges traditional housing affordability benchmarks. This finding comes from the latest NAHB/Wells Fargo Cost of Housing Index (CHI), a quarterly analysis of housing costs across the United States. For a family earning the national median income of $106,800, the mortgage payment for a median-priced existing home, valued at $434,900, now requires 36% of their income. Similarly, purchasing a new median-priced home at $410,700 necessitates 34% of their income. These figures represent an increase from the first quarter of 2026, when mortgage payments accounted for 32% of income for both existing and new homes. The CHI calculates this ratio by dividing the mortgage payment by the median family income. The mortgage payment itself is determined by taking the median home price, assuming a 10% down payment, and adding property taxes, homeowners insurance, and private mortgage insurance (PMI). The worsening housing affordability has led many prospective buyers to question their ability to purchase a home. Financial experts are re-evaluating popular budgeting guidelines, such as the 28/36 rule, which suggests spending no more than 28% of gross monthly income on housing and no more than 36% on total debt, and the 30% income rule, which caps housing costs at 30%. Linda Grizely, a certified financial planner, suggests that while these rules are useful starting points, they do not account for individual circumstances. She emphasizes the importance of assessing whether enough income remains after housing payments to cover other essential expenses, savings for emergencies and retirement, debt repayment, and discretionary spending, in addition to the ongoing costs of homeownership. Stephen Kates, principal at Clocktower Financial Consulting, views these guidelines as crucial benchmarks for buyers, particularly in the current market environment. He notes that in markets where housing costs are exceptionally high, buyers may need to adjust their expectations regarding the traditional affordability metrics. The increasing burden of mortgage payments on family incomes underscores a broader trend of declining housing affordability, driven by a combination of rising home prices and interest rates, which together increase the monthly cost of homeownership. This situation is creating significant hurdles for first-time homebuyers and those looking to upgrade, potentially delaying homeownership or forcing them to seek less expensive markets. The NAHB/Wells Fargo Cost of Housing Index provides a critical, data-driven perspective on this evolving landscape, highlighting the financial strain placed on American households striving to achieve homeownership.
