Northern Illinois Housing Market Update - May 2026

As the spring season matured into May, the narrative in Northern Illinois continued to be defined by a lack of supply. Inventory drops widened to double digits year over year. Despite fewer options causing closed sales to lag behind 2025's pace, the intense competition for available homes drove median prices up notably for another consecutive month.

  • Attached median price: $310,000 (+3.3% YoY)
  • Closed sales dipped slightly: detached (-4.9%) and attached (-2.8%)
  • New listings took a noticeable step back: detached (-8.7%) and attached (-7.1%)
  • Market time continued to compress under buyer pressure
  • Months supply crept up slightly but stayed firmly low at 2.0 (detached) and 1.9 (attached)

What This Means for Sellers

  • The lack of new listing competition means your property will enjoy maximum visibility.
  • With attached homes receiving over 99% of their original list price, you have excellent negotiating leverage.
  • Buyers are serious and acting fast, so be prepared for a quick timeline to closing.

What This Means for Buyers

  • Fewer new listings this month mean you will likely face multiple-offer scenarios.
  • Expanding your search radius or considering different property types (e.g., attached vs. detached) might be necessary to secure a home.
  • Ensure your agent is alerting you to listings the minute they go live.
