Karla, Oak Park is a very diverse community, and, as a native, I can tell you that most Oak Parkers love their particular corner of the town best. Every section has its own personality, and the home styles vary greatly among the different areas. That being said, there is a typical Oak Park style home, usually built about 100 years ago, that is prairie in flavor, whether it is an oversize Craftsman bungalow, or an American four square, that would hold its value best. We prize original architectural details, such as custom millwork, plaster cove moldings, built in bookcases and art glass windows, and a house that has those details will sell faster than other homes in its price range.
I hope that helps!
