There are three Eichler sub-divisions in Concord with a great Eichler-enthusiast community. Many sensitively renovated homes here! Eichler neighbors can participate in monthly speghetti dinners, holiday events, July 4th parade, welcome to the neighborhood parties. After looking for an Eichler for 3 years in the SF Bay Area, we settled on Concord not only for the price, but the peace & quiet and how accessible it is to SF via BART. Houses come up here every so often, check listings daily because they go fast in the SF Bay Area market. (I'm an Eichler owner and Eichler blogger, not a real estate agent).
We've had a number of houses come up for sale lately! More info on the neighborhoods, locations, etc. http://www.redneckmodern.com/2013/04/concord-eichlers-101.html
