Buffalo Grove, Illinois is located about 30 miles north/northwest of Chicago. Buffalo Grove has long been known to have one of the best school districts in the state of Illinois. The area has two high schools, Buffalo Grove High School and Adlai E. Stevenson High School. While Buffalo Grove High School is a very good school it’s Stevenson High School that gets all of the attention for being one of the best in the state. The majority of the housing are Single-Family homes, but there are also town homes and condos in the area. Prior to 2007 it would cost at least $400,000 for an updated 2,000 sq. ft. home but since then prices have made Buffalo Grove a lot more affordable.
