I recently compiled the stats on the single family homes that closed in June '09 in Oak Park...
I'd be happy to provide you with similar info for condos in the area...
The long and the short of it is that pricing, the home's showing condition, and marketing determine the DOM. We've sold several single family homes and condos in the area in the past year well under the average DOM.
We'd love to help you with your Oak Park area real estate needs. Please contact us via the website below if you have further questions. Best of luck!
