How Competitive is the Northbrook, IL Housing Market?

by Sara Sogol

Northbrook, a city near Chicago, IL, is a highly competitive housing market. About 54% of homes sold above list price in the 3 months ending June 2026, and the typical home sold in just 42 days.

The National Picture

U.S. homes sold above asking at a 24.6% clip in June 2026. In Northbrook, that figure reaches 54.2%—nearly three times the national rate. The gap makes clear that buyers here need to come prepared to compete aggressively from day one.

Declining Inventory Supports Steady Overbidding

Active listings declined 11% year over year—the steepest inventory drop among these North Shore cities. That shrinking supply supports a 102.3% sale-to-list ratio and 54% sold-above rate. Neighboring Glenview (103.9% sale-to-list, 62% off-market) runs slightly hotter, and Highland Park (104.1%) commands an even steeper premium. Northbrook's declining inventory suggests competition may intensify further.

Why is Northbrook Highly Competitive?

Northbrook is highly competitive because affluent buyers compete aggressively for a small number of listings in a low-discount market. At 2.4 months of supply, the market tilts firmly toward sellers. Price drops affect just 15% of active listings, showing most sellers price accurately. Days on market shrank 2 days from last year, reflecting an accelerating pace.
