Spring inventory growth remains staid in the Twin Cities housing market as the annual influx of new properties for sale has not been as rambunctious as the levels seen over the last few springs. The total number of homes for sale in the metro area currently sits at 31,615 up only 3.0 percent from the same time last year -- the lowest such year over year increase for some years. Home sales remain relatively slow as well, with newly signed purchase agreements ( pending sales ) from the last three months trailing the same period last year by 16.6 percent.
