Bank of America's stock market research team which covers the housing industry puts out a fantastic monthly research report in which they share the results of a survey of 2400 Realtors from around the country. They ask about buyer traffic trends, price changes, selling incentives, and other issues. They analyze the results individually for about 40 metro areas. It differs from all the other housing data you see because it's the only survey that I'm aware of which actually ask Realtors about current market conditions.

This month's survey is summed up by its headline: "Another Quiet Month with Few Buyers Swayed by Lower Prices".
