When corporate America's executive relocate to the Chicago area, Hinsdale is usually one of he suburbs that is recommended. It has excellent school, a historic downtown, charm of a small town yet close to all major expressways, the two major airports, world class shopping within a couple of miles, and a quick 22 minute morning train ride to downtown Chicago. I my opinion, these are great reason for the demand. As is usually the case price follows supply and demand. My fellow agents have addressed some other reasons, which too have an impact.
Simple. Supply is down and demand is still high. Prices in Hinsdale stopped declining about 18 months ago. All forecasts for the Western Suburbs of Chicago is a continuation of the upward trend. It is still a good time to be a buyer because of the low interest rates. It is now a good time also to be a seller because there is a lower inventory than in the past years -- homes are selling. I keep track of the local statistics by town on a quarterly basis.
It might have to do with lower end houses selling and higher end houses remaining on the market, since there are many properties that have had at least some price cuts. But as the other replies indicate, Hinsdale is prime, a community that, because of teardowns, albiet they have slowed, consistently improves over time. Great schools great location. Like another answer, the best place in the western suburbs to go if you have over $1M to spend and want some kind of reassurance that you will get your money back.
Affluent communities are less impacted (in general) by economic downturns. Hinsdale has excellent access to the commuter trains for executives with offices in Chicago. Many work in nearby communities like Oak Brook too. Schools are well rated, Oak Brook Mall & other high end shopping areas are nearby etc... Where would you choose to buy in the western burbs if spending over $1m and be comfortable there would be buyers waiting if you needed to relocate?
