Buffalo Grove 60089 is in Lake, IL, part of the Chicago Metro. The ZIP-wide typical value in Buffalo Grove 60089 is $444,313 (Zillow Home Value Index, September 2026), up 5.8% from a year earlier. Homes that sold went under contract in a median 46 days, and 24% of listings took a price cut (Redfin Data Center, period ending Sep 30, 2026). On Lotvox's market-leverage reading of that data, with 2.5 months of supply, neither buyers nor sellers hold a clear edge. The Lotvox Turnover Index is not published for 60089 yet: it appears only where a held-out test on the county's recorded sales beats chance. Across Lake's 26 ZIPs with a Zillow value, the middle one is $373,177, so 60089 sits 19% above the county middle. Typical rent is $2,402 a month (Zillow Observed Rent Index, September 2026). Lotvox holds county assessor records for 9,806 properties in 60089.

Redfin market data (county + ZIP), via Lotvox. As of 2026-09-30. Normal = same-month median of monthly rates, minimum 3 same-month points. Source window 3 months (flows shown per month). months_of_supply is not published at this grain (0 non-null rows measured); derived here as active listings / closed sales per month. A fresher supply-only read (44 new, 93 active, 2026-09-01, Realtor.com inventory (county + ZIP), via Lotvox) is available but is NOT used in the net — that source publishes no closed sales, so subtracting across it would mix two vintages.

Price Bands — the median behind the median
A single median rises whenever expensive homes become a bigger share of what sells, even if no tier got more expensive. These are the tiers underneath it, computed from recorded arms-length deed transactions in Lake.

No mix-shift history for this area. no geography from this ZIP up to metro has 8+ quarters of 10+ recorded arms-length sales across at least 4 price tiers. Trends are drawn only from recorded transactions; the last-sale snapshot above cannot carry a time series, because a property that sold twice keeps only its latest sale — which drags the history upward through the tiers and would invent the very mix shift this section exists to test for.

Owner stock, age of householder
Tenure by age of householder (ACS B25007) is not published below county. Any ZIP figure here is DERIVED from the county's age-specific owner rates applied to this ZIP's own age structure — never read directly.
Derived — this ZIP
No ZIP figure — this ZIP spans 2 counties
NOT DERIVED: this ZIP spans more than one county. Tenure by age is not published below county, and no single county rate applies here. Weighting by area would produce a number, not a measurement - area is a poor proxy for where households are. Each county's own figure is shown instead.
