Although not technically in the suburbs I would recommend looking into areas on the outskirts of the city. Some areas that come to mind are the Near West Side and Southwest Sides of Chicago. On the Near West Side there is a new development called The Heritage Homes of West Village. They offer walk-up condominiums, simplexes, duplexes, and townhomes within the price range you are looking for. It is a nice area with a friendly neighborhood feel but is also a short commute (5 to 10 minutes) to W Jackson. Visit

Park Place Homes is another new development which is on the Southwest Side that also is part of Chicago but is little bit less urban. They have single family homes and townhomes that meet your price criteria. The commute from this location is also easy, about 20 minutes. Visit
