The Minneapolis Area Association of Realtors puts out an annual report that summarizes yearly activity on both a regional and city level. It’s jam-packed with information that is great for getting a feel for what happened in the previous year.
In March, MAAR issued the 2006 Residential Real Estate Activity Report. This is available from their web site directly, but I’ve also seen some agents telling web site visitors that they’ll email them the report only after giving the agent their contact information. This is a free and publicly available report… you don’t need to give up anything to read it.
