I realize you asked this question a while back, but I guess it's never too late to just answer a query. I can't give you the average closed price on duplex/triplex sales in the last six months, because Idaho is a non-disclosure state. However, I can tell you that the average list price for such properties that have closed in the last six months is right about $211k, with an average time on the market of 97 days. These results are for Hayden and Couer d'Alene, as you mentioned those were your areas of interest. I do hope this helps you. Have a lovely day.
