Yesterday, S&P released Case-Shiller Index data for April, and the results are somewhat encouraging. Out of the 20-city composite index, 18 showed month-over-month improvement. What is more, San Francisco led the pack, registering an 18% year-over-year gain, showing conclusively that happy times are here again, right? Well, maybe not. But hey, at least we beat NYC. In fact, New York fared second to last, beating out only the over-built condo capital of the US, Miami, FL. SFO! SFO!
