The Case-Shiller Index for March just came out and showed a big jump, just beginning to reflect the surge in appreciation weâ€™ve been experiencing in 2013. (January and February Index readings mostly reflect sales in late 2012.) The March reading was 3.5% higher than February (last month) and 15% higher than March 2012.
The Index is for the 5-County SF Metro Area, not just for the city of San Francisco, and since it reflects a 3-month rolling average, is published 2 months later and sales close 4-8 weeks after the offers are negotiated, it is typically 3-5 months behind the actual market on the street. I would expect another significant jump in Aprilâ€™s Index.
