My trusty spreadsheet reviewed data from Cotality previously known as CoreLogic tracking the share of single-family home purchases made by people not occupying the property. My focus was on the average pace of the past 18 months last year and the first six months of 2025 and how those investment patterns compared to the previous nine years. What stands out: Seven of California's 10 most significant increases in investor share of homebuying were nowhere near the Pacific.
