California’s housing market isn’t immune to reversals—and in some towns, the early signals are hard to ignore. Drawing on 15 years of Zillow Home Value Index data, we’ve pinpointed 21 communities where conditions are starting to echo the lead-up to past corrections. These places show a risky blend of overvaluation, slowing growth, past crash patterns, and price volatility. From pricey beach cities to overheated inland suburbs, these towns may be the first to feel a shift in 2025.

Placentia’s housing market shows several red flags that suggest a potential correction may be looming. With two significant historical crashes and home values sitting 91.1% above their long-term average, the market appears dangerously overextended. The town’s 350.9% price increase since 2000 far outpaces wage growth in the region, creating an unsustainable situation according to housing economists.
Placentia – Severely Overextended Beyond Historical Norms
Located in northern Orange County, Placentia combines suburban comfort with proximity to major employment centers. The city’s current median home price of $1,117,574 represents a staggering 350.9% increase since 2000, pushing affordability to breaking points for many residents. According to the California Association of Realtors, Placentia’s price-to-income ratio has reached 9.3, well above the 3.0 considered healthy by housing economists.
The city’s history of volatility is concerning, with two previous crashes exceeding 8% and its worst drop of 15.6% occurring during the 2008 financial crisis. California Department of Finance data shows that local income growth has averaged just 2.9% annually over the same period, creating a dangerous disconnect between housing costs and economic fundamentals. With prices now sitting 91.1% above the long-term trendline, mathematical regression to the mean suggests a significant correction is statistically probable.

Yorba Linda – Luxury Market Showing Unsustainable Growth Pattern
Known as the “Land of Gracious Living,” Yorba Linda has seen its housing market soar to precarious heights. The current median home price of $1,430,480 represents a 306.9% increase since 2000, creating what housing economist Dr. Ralph McLaughlin calls “a textbook example of unsustainable appreciation.” According to the California Department of Real Estate, Yorba Linda’s inventory levels hit a 15-year low in early 2025, further driving up prices.
The city’s pattern of volatility is particularly concerning, with annual price swings averaging 10.2% and two previous crashes exceeding 8%. Census data shows that while Yorba Linda’s median household income ranks among Orange County’s highest at $164,000, housing prices have grown at nearly triple the rate of local wages. With mortgage rates rising and the market sitting 84.2% above its long-term average, real estate analysts at CoreLogic have flagged Yorba Linda as having a “severe risk of price correction” in their latest housing stability report.

Nestled in the Saddleback Valley of Orange County, Lake Forest has transformed from a moderate-cost community to a high-priced suburb with a current median home value of $1,244,889.

The city’s vulnerability stems from several factors, including its 98.7% overextension above long-term averages and relatively high price volatility with annual swings averaging 11.2%. According to housing data from the California Association of Realtors, Lake Forest’s months-of-inventory recently hit 4.2 months, the highest level since 2019, suggesting buyer demand may be cooling. The city’s history of two previous crashes exceeding 8%, including a steep 16.8% decline during the 2008 financial crisis, demonstrates that this market is capable of significant corrections when economic conditions shift. With mortgage applications dropping 23% year-over-year according to the Mortgage Bankers Association, Lake Forest appears primed for a potential price adjustment.

Newport Beach – Ultra-Luxury Market At Peak Vulnerability
This coastal Orange County paradise boasts some of California’s most expensive real estate, with a current median home price of $3,457,576 that places it among the nation’s priciest markets.

Newport Beach’s housing values have increased by 387.2% since 2000, while experiencing moderate volatility with annual price swings averaging 10.4%. Though the city has experienced only one major crash historically, that 13.3% decline in 2008 proved that even ultra-luxury markets can suffer significant corrections. Recent data from the Orange County Assessor’s Office shows concerning signs: luxury home sales over $5 million dropped 31% in the first quarter of 2025 compared to the previous year, while days-on-market increased from 45 to 78 days. With prices now sitting 98.4% above long-term trends and foreign investment slowing according to the National Association of Realtors, Newport Beach appears vulnerable to market forces that could trigger a significant downward adjustment.

Housing economist Dr. Michael Fratantoni notes that “gated communities like Coto de Caza experienced outsized price growth during the pandemic as wealthy buyers sought space and security, creating a potential for outsized corrections as those motivations fade.” With prices now sitting 92.5% above long-term trends and interest rates on jumbo mortgages continuing to rise, Coto de Caza appears increasingly vulnerable to market forces that could trigger a significant price adjustment.

This unincorporated area of Orange County, sometimes known as Tustin Hills or Cowan Heights, has seen its housing market reach precarious heights with current median home values at $1,788,174. According to data from the Orange County Assessor’s Office, North Tustin’s larger lot sizes (typically half-acre to full-acre) and semi-rural character have made it particularly attractive during the pandemic-era search for space.

Irvine – Orange County’s Most Mathematically Overextended Market
As Orange County’s economic center and one of California’s most successful planned communities, Irvine has seen its housing market reach unprecedented heights, with current median home values at $1,615,157. According to data from the California Department of Finance, Irvine’s population has grown 39% since 2000 while housing prices have skyrocketed 410.9%, creating what economists call a fundamental supply-demand imbalance.
What makes Irvine particularly vulnerable is its 111.1% overextension above long-term averages—the highest percentage in our entire analysis—meaning current prices are more than double what historical trends would suggest is sustainable. The Federal Housing Finance Agency identifies Irvine as California’s most mathematically overvalued major market relative to historical trendlines.
