Original analysis of Chicago luxury price bands reveals large differences in sales relative to inventory, including a balanced upper attached tier.
Evidence: August 2026.
Calling Chicago luxury a seller's market is accurate under the Institute for Luxury Home Marketing's overall classification. It is also incomplete. Regrouping the report's price bands shows substantially different sales activity relative to inventory as the price range rises.
For single-family luxury, three groups built from complete published bands produce the following results:
| Price group | Inventory | Sales | Sales / inventory |
|---|---|---|---|
| $850,000 to under $1.9 million | 292 | 279 | 95.5% |
| $1.9 million to under $2.9 million | 110 | 63 | 57.3% |
| $2.9 million and above | 116 | 30 | 25.9% |
All three groups remain above the publisher's 21% seller-market threshold. Yet the lowest group's ratio is approximately 3.7 times the highest group's ratio. A shared classification does not mean a shared competitive environment.
Attached luxury has an even clearer classification difference
The same exercise for attached luxury produces a 67.8% ratio from $750,000 to under $1 million, 46.1% from $1 million to under $2.5 million, and 13.7% at $2.5 million and above.
The upper attached group had 73 inventory and 10 sales. Under the Institute's thresholds, that group's ratio is balanced, although the full attached luxury segment is classified as a seller's market.
The result identifies a segment worth examining separately. It does not establish a universal negotiating discount, and the upper group's 10 sales make a single month's result sensitive to relatively few transactions.
The pattern is not a smooth staircase
Individual bands are uneven. The single-family $1 million to $1,099,999 band had 24 sales against 13 inventory, while the $1.7 million to $1,899,999 band had 36 sales against 34 inventory. Ratios can exceed 100% because the sales and inventory counts are different populations measured over different intervals.
At the other end, the two single-family bands beginning at $5.3 million together had two sales against 28 inventory. That is a thin sample, not a reliable prediction of how a particular high-end home will perform. Even within those two bands, the outcomes differ: one had no sales and the other had two.
The broad groups describe a gradient. They do not prove that every successive increase in price reduces market activity, or that crossing a group boundary causes a property to sell differently.
Compare the competitive set before choosing a strategy
For sellers, the relevant evidence starts with homes a buyer would consider substitutes: similar price, location, usable space, condition and ownership structure. A broad seller-market headline can obscure a much deeper pool of alternatives in a particular upper tier.
For buyers, differences among price brackets can guide which competing listings deserve investigation. They do not establish seller motivation, concessions or the likelihood that a particular offer will be accepted.
The source bands are a starting map. Listing histories would be needed to learn whether price reductions moved properties between bands and whether those changes affected eventual outcomes.
