Do you sometimes lose track of when the various housing and economic reports are coming out? It’s easy to do, but since newspapers start buzzing as soon as the Case-Shiller housing numbers or new unemployment figures are released, it’s good to know in advance what’s coming up. That’s where MarketWatch.com’s economic calendar page comes in handy. It shows you the time and date of each upcoming economic report release, and provides the previous report’s data for comparison. For example, coming up this week are the Cash-Shiller home price report for January, pending home sales data, and the unemployment rate for March 2011 – all numbers that are likely to affect the real estate market.
