California housing affordability showed modest improvement at the end of 2025, offering cautious optimism for homebuyers across the San Gabriel Valley.
According to fourth-quarter data, the statewide Housing Affordability Index rose to 18 percent in Q4 2025. That marks a one percentage point increase from the third quarter and a two-point gain compared with the same period in 2024.
The improvement reflects a combination of moderating home prices and slightly lower borrowing costs, though affordability remains historically constrained.
Median Price And Mortgage Costs Decline
The statewide median price for existing single-family homes eased in the fourth quarter as buyer competition cooled and seasonal patterns slowed the market.
At the same time, borrowing costs continued a gradual decline. While mortgage rates remain elevated by long-term standards, they reached their lowest level in nearly two years during the quarter.
As a result, the monthly mortgage payment for a median-priced home, including taxes and insurance, fell 4.7 percent from the prior quarter. Compared with a year earlier, the payment dipped 4.0 percent.
The effective mortgage rate declined on both a quarter-to-quarter and year-over-year basis, contributing to the lower monthly cost for buyers.
What The Housing Affordability Index Means
The Housing Affordability Index measures the percentage of households that can afford to purchase a median-priced home in California. An index of 18 percent means fewer than one in five households earn enough income to qualify for a conventional mortgage on a median-priced home.
Although the latest figures show improvement, affordability remains far below historical norms. Many communities in El Monte, South El Monte, Baldwin Park, Rosemead, Arcadia, Temple City and Irwindale continue to face high home prices relative to local incomes.
For first-time buyers, even small shifts in mortgage rates can affect purchasing power. A modest decline in rates reduces monthly payments and may allow some households to qualify for financing.
Local Impact In The San Gabriel Valley
In the Mid Valley, where housing demand remains strong and supply limited, statewide affordability trends often play out unevenly. Lower mortgage payments may ease pressure for some buyers, but elevated prices still present a barrier for many working families.
Real estate professionals note that seasonal slowdowns often bring price adjustments in late fall and winter. Whether the fourth-quarter gains continue into 2026 will depend largely on interest rate trends and housing inventory levels.
