Different counts, different numbers
Local data can differ. The Santa Clara County Association of Realtors reported a September median of $1,880,000 for single-family homes, down 4% from a year earlier, with 726 sales. C.A.R. notes that medians reflect the mix of homes sold and shouldn't be read as the change in value of any particular home.
The backdrop: The 30-year fixed mortgage rate averaged 6.86% in September, C.A.R. said.
