A Who's Who of Minnesota execs, including Jay Lund, CEO of Andersen Corp., and Trudy Rautio, CEO of Carlson, will be swinging hammers in north Minneapolis on Monday to celebrate Twin Cities Habitat for Humanity's 13th Annual CEO Build Day.

Lund and Rautio are CEO Build Day co-chairs, and they will be helping volunteers from more than two dozen companies build a pair of houses that will be sold to moderate-income families. Because of a disparity between construction costs and market values in the area, buyers of both houses will pay far less than what it actually costs to build the houses.

The 1,676 square-foot house at 3026 Logan Av. N., for example, appraised for $165,000, but the buyer will pay only $132,000. Habitat will hold the remainder of the value, about $33,000, as a forgivable second mortgage and gets the right of first refusal if they sell before paying off the mortgage. Buyers must have a family income 30 to 60 percent of the Twin Cities area median income to qualify. Both houses are spoken for, by the way.
