U.S. Housing Is 26% Overpriced — Why Orange County Tops the List

• Buyers who need a mortgage should calculate affordability using realistic mortgage rates, not the lows from 2020–2021. Stress-test budgets for rate reversion in either direction.
• Investors should price in longer holding periods if they count on price appreciation to deliver returns. Overvalued markets typically require either time for fundamentals to catch up or an external shock such as rate cuts.
• Consider markets with lower overvaluation and resilient economies. Austin at 6% overvaluation is an example where price resets have already occurred and net expected returns are more predictable.
• For rental investors, evaluate rent-to-price ratios and cap rates. In very overvalued markets, initial yields are compressed and vacancy and expense shocks will erode returns quickly.
• For homeowners, understand the trade-off between buying now at elevated prices and waiting for a correction that could improve long-term returns but leave you renting and paying more cash monthly in the interim.

A short checklist for prospective buyers and investors

• Calculate required household income and down payment against local median price.
• Use a conservative mortgage rate for monthly payment projections.
• Compare local overvaluation percentage to the national median of 26%.
• Assess job-growth indicators for the metro — wage growth reduces the likelihood of price declines.
• If investing, run sensitivity analyses on rent declines and cap rate expansion.

Possible paths to market normalization

The grand question in the industry is what combination of forces will cause prices to realign with fundamentals. John Burns highlights the usual suspects: more construction, more sellers listing, cheaper mortgages, higher incomes, and price cuts. We can be more specific about likelihood and timing.

• Mortgage rates: A sustained decline in rates would immediately restore buyer purchasing power. However, rates are set by macro factors outside local control, and forecasts vary.
• Income growth: Faster wage gains in a metro reduce overvaluation without price drops. This is a slow process and depends on local economic policy, industry mix and migration patterns.
• Inventory and new construction: Building more homes reduces pricing pressure, but supply-side solutions take years to materialize and face regulatory barriers in many metros.
• Price adjustments: In markets with weak job growth and high overvaluation, price cuts are already happening or may be required. Austin shows how a slowdown can lead to meaningful repricing.

My assessment is straightforward: a durable return to equilibrium usually requires a mix of at least two of the above factors. Sole reliance on higher incomes or lower rates alone is risky.

Where opportunity still exists

We do not think all hope is lost for buyers or investors. Opportunities are selective and require active underwriting:

• Secondary and tertiary markets with lower overvaluation and positive demographic trends can offer better midterm returns.
• For investors seeking cash flow over appreciation, look for metros where rents are growing faster than purchase prices.
• In California, the East Bay and Sacramento show smaller overvaluation percentages and may be better bets for investors focused on midterm stability.

But be realistic: markets where overvaluation exceeds 25% are priced for a best-case scenario of sustained income and rate trends. That scenario is not the base case today.

Risks to watch

• A rapid increase in mortgage rates would reduce affordability further and press prices. That move would be painful in overvalued markets.
• A sharp economic slowdown in a local market can cause price corrections and damage investor returns, as occurred in some Sun Belt metros when tech hiring cooled.
• Policymakers could change tax or lending rules that shift demand quickly, creating winners and losers across metros.

We recommend scenario planning for at least three outcomes: shallow correction (5–15% price decline), deeper correction (15–30%), and prolonged stagnation. The current 26% national overvaluation makes a deeper correction a credible risk in the absence of quick rate relief or strong income gains.

Conclusion: a more cautious, data-driven approach

John Burns’ study forces a reckoning. The headline that the typical U.S. home is 26% overvalued is uncomfortable but useful. California’s average overvaluation of 18% shows the problem is national, not just coastal. Orange County’s 35% gap is a warning sign for buyers who assume prices can only go up.

For buyers and investors, the practical takeaway is to focus on cash flow, stress-tested affordability and local economic indicators. If you are relying on price appreciation to justify a purchase or investment in a market that is 25% or more overvalued, you should have a clear plan for how you will handle a multi-year stagnation or a double-digit price correction.

We will watch mortgage rates, wage growth and new listings closely. These three variables will determine whether prices revert to fundamentals over months or require years. The chart of overvaluation numbers from John Burns is the best reminder that real estate is a financial market governed by incomes and borrowing costs, not hopes alone.

Frequently Asked Questions

Q: What does it mean for a market to be "overvalued" by 26%?

A: Overvaluation in the John Burns framework means median prices are 26% higher than what long-term relationships among prices, mortgage rates and incomes would support. Practically, buyers must pay more relative to household incomes and typical financing costs than the historical norm.

Q: Is California the worst place to buy right now?

A: Not necessarily. California has some highly overvalued submarkets, but the state’s median overvaluation of 18% is lower than the 25% median in 25 non-California markets. Each metro must be judged on its overvaluation percentage, job growth and supply dynamics.

Q: Could mortgage rates dropping solve the overvaluation problem?

A: Lower rates would increase buyer purchasing power and could narrow the gap, but rates alone may not be sufficient. Lasting alignment usually requires a combination of rate relief, income gains and more supply.

Q: Where should investors look if they want lower risk?

A: Consider markets with lower overvaluation percentages, steady job growth and reasonable rent-to-price ratios. Also run stress tests for rate increases, vacancy and maintenance cost shocks. Austin’s recovery to 6% overvaluation after price adjustments shows the value of buying where fundamentals are improving.
