I don't know if you have had an opportunity to speak with a Realtor yet, but there are several items they could help you with. A Realtor would be able to tell you what properties have sold recently in the Hinsdale area, and approximately how long properties are staying on the market before they sell. Also, a Realtor would be able to give you a better understanding of what improvements would add resale value to your home, and what improvements will most likely not be recouped at the time of a sale. I would love to answer any questions that you may have. Feel free to send me an e-mail to set up a convenient time to discuss these things.
