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.
21. Placentia – Crash Risk Percentage: 90%
- Crash Risk Percentage: 90%
- Historical crashes (8%+ drops): 2
- Worst historical crash: -15.6% (2008)
- Total price increase since 2000: 350.9%
- Overextended above long-term average: 91.1%
- Price volatility (annual swings): 10.4%
- Current 2025 price: $1,117,574
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.
20. Yorba Linda – Crash Risk Percentage: 90%
- Crash Risk Percentage: 90%
- Historical crashes (8%+ drops): 2
- Worst historical crash: -14.7% (2008)
- Total price increase since 2000: 306.9%
- Overextended above long-term average: 84.2%
- Price volatility (annual swings): 10.2%
- Current 2025 price: $1,430,480
Yorba Linda’s housing market displays troubling signs of potential instability with prices now 84.2% above their long-term average. Historical data shows the market has crashed twice before, with a worst-case drop of 14.7% during the 2008 recession. The combination of high volatility and extreme price growth since 2000 places this affluent Orange County community at significant risk for a market correction.
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.
19. Lake Forest – Crash Risk Percentage: 90%
- Crash Risk Percentage: 90%

- Price volatility (annual swings): 11.2%
- Current 2025 price: $1,244,889
Lake Forest’s housing market exhibits clear warning signs of an impending correction. With prices sitting 98.7% above the long-term average—nearly double what economists consider sustainable—and a history of sharp declines including a 16.8% crash in 2008, the current market appears dangerously inflated. The town’s 373.9% price growth since 2000 has created a severe disconnect between housing costs and local economic fundamentals.
Lake Forest – Nearly Double Its Long-Term Price Trend
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. Analysis from the Federal Reserve Bank of San Francisco identifies Lake Forest as one of California’s most overvalued markets, with prices that have rocketed 373.9% since 2000 despite median household income increasing by only 87% during the same period…
