Florence, from my perspective, a realtor, based on permit surveys and listing prices of homes in Glencoe on lots with area of 7400-9100, the prices range from $389-$480 PSF. Most construction is masonry and include appliances and finishes. Most of these homes are located in south , central Glencoe on streets named for the early presidents. They offer an easy walk to the Metra Station. The list prices reflect a land cost to finished end product ratio of, say, 38%. This ratio is based on averages since 2000. You may know that the spec buiders in Glencoe have been over positioned since 2005 and the price of a tear down on a 50 x 182 has fallen 20% from its 2005-2006 peak and currently trade between $365,000-to about $430,000. Tree permit fees may be significant. This analysis also applies to Northbrook, Dist 28.
