To get straight to the point, the median home price in Arlington Heights, IL in 2026 is expected to be around $475,000. This is clear. The Zillow Home Value Index records $470,945, which is a 6.9% increase from the previous year, while the median listing price according to Realtor.com is $492,500, up 5.24%. In contrast, Redfin's median sale price for February 2026 is reported at $407,500, reflecting differences in measurement methods. Redfin counts only completed sales, while Realtor.com tracks current listing prices, and Zillow uses a repeat sales model, resulting in different figures.

The current market is primarily affected by a shortage of supply. According to the Illinois Realtors' January 2026 forecast report, the inventory of single-family homes in the Chicago metropolitan area has decreased by about 11% compared to the previous year. Arlington Heights is no exception, with a pattern of rapid sales whenever new listings appear. Redfin data shows that as of February 2026, there were an average of three offers per home, and 40% of all transactions were completed above the asking price. This indicates a seller's market is continuing.

Mortgage interest rates are also impacting market trends. As of 2026, the 30-year fixed rate is hovering in the mid-6% range, which continues to burden buyers in terms of purchasing power. The market hotness index for Arlington Heights according to Realtor.com is 95, and the contract-to-listing ratio is at 100%. These figures indicate that demand is fully absorbing supply, meaning homes are selling as soon as they hit the market.

Here are the key data points summarized:

• Zillow Home Value Index: $470,945 (up 6.9% year-over-year)
• Realtor.com median listing price: $492,500 (up 5.24% year-over-year)
