For many would-be homebuyers, a house that’s sat on the market for over 30 days in early summer raises a red flag. But a month may be a new normal in the Bay Area. Across Alameda, Contra Costa, San Francisco, San Mateo and Santa Clara counties, about 53% of active home listings in June 2024 were “stale,” sitting on the market for 30 days or more without going under contract, a 6.5% increase from last June, according to a new report from real estate brokerage Redfin. Nationally, the number of aging listings was 64.7% in June- almost 9% higher than 2023.
