Every figure, with its source and period.
The source column matters as much as the value. Each row states the reporting period it describes.
| Metric | Value | Source · period |
|---|---|---|
| Median sale price | $1.1M | Redfin · three months ending July 2026 |
| Year-over-year price change | up 3.5% | Redfin · three months ending July 2026 |
| Median sale price per square foot | $256 | Redfin · three months ending July 2026 |
| Year-over-year change per square foot | up 17.4% | Redfin · three months ending July 2026 |
| Median days on market | 53 days | Redfin · three months ending July 2026 |
| Median days on market, same period last year | 37 days | Redfin · three months ending July 2026 |
| Average offers per home | Not published by the provider for this city | — |
| Homes sold, July 2026 | 28 | Redfin · July 2026 |
| Homes sold, July 2025 | 37 | Redfin · July 2025 |
| Market competitiveness (Redfin's wording) | somewhat competitive | Redfin · three months ending July 2026 |
Redfin states its calculations use MLS and/or public-record data. Rolling three-month figures smooth out short-term swings, which is useful in smaller cities where a handful of sales can move a monthly median sharply.
What the published numbers mean if you are selling.
The median sale price in Long Grove was $1.1M over the three months ending July 2026, up 3.5% against the same period a year earlier. Price per square foot was $256, up 17.4% year over year. Those two measures do not always move together, and when they diverge it usually reflects a change in the mix of homes selling rather than a change in what any one home is worth.
Homes sold in a median of 53 days, compared with 37 days a year earlier — slower than last year. Redfin describes the market as somewhat competitive.
28 homes sold in July 2026 against 37 in July 2025 — fewer closings than a year ago. Volume tells you how much evidence the market is producing; in the smaller villages a single unusual sale can visibly move a citywide figure, so treat these medians as direction rather than precision.
Practically: price to the evidence for your own property type and neighborhood rather than to a citywide median, invest in presentation before price reductions, and decide your response to inspection findings before you are negotiating them. For a number tied to your address, a complimentary local pricing review is the right starting point, and my seller services page explains the process.
What the published numbers mean if you are buying.
Year-over-year change in the median sale price was up 3.5%. Past change is not a prediction of future change, and no newer city-level month had been published when this update was written.
Redfin does not publish an average-offers figure for Long Grove, so competition here has to be judged case by case rather than from a citywide statistic.
A median of 53 days on market also means some homes genuinely sit. Listings with longer market time may merit closer review for possible negotiating room, though this is not guaranteed and depends entirely on the specific property.
Strong financing preparation, including full underwriting where a lender offers it, can strengthen an offer alongside price. You should not assume inspection or appraisal protections must be waived. My buyer services page covers offer structure, and the Long Grove community page covers housing stock, schools and commute detail.
Interpretation, not prediction.
What follows is my professional interpretation of the published figures above. It is not a forecast, not a statistic I produced, and not personalized advice.
Reading the Long Grove figures together, the median sale price is up 3.5% year over year while homes are taking a median of 53 days to sell. A rising median alongside a market Redfin calls somewhat competitive tells me buyers are still selective: well-prepared homes at defensible prices move, and the rest wait. Citywide medians describe the middle of a varied market — a townhome and a large single-family home in the same city can be travelling in opposite directions.
For sellers, that argues for accurate pricing and genuine presentation. For buyers, it argues for settling financing and offer strategy early so you can act on the right home quickly, without automatically waiving protections. If you want the comparable evidence for your own address, you can request a call, or browse market updates for the other northwest suburbs.
Common questions about the Long Grove market.
What is the most recent Long Grove market data available in September 2026?
As of September 7, 2026, the most recent city-level figures published for Long Grove cover the three months ending July 2026. Redfin reported a median sale price of $1.1M, up 3.5% compared with the same period a year earlier. August and September 2026 city-level figures had not been published when this update was written, so this article does not state them and does not estimate them.
What is a typical home price in Long Grove right now?
Redfin reported a median sale price of $1.1M for the three months ending July 2026, up 3.5% year over year, and a median sale price per square foot of $256, up 17.4% year over year. A citywide median describes the middle of all sales; it is not a valuation of any particular home.
How competitive is the Long Grove market?
Redfin characterizes Long Grove as somewhat competitive. Homes sold in a median of 53 days over the three months ending July 2026, compared with 37 days in the same period last year. 28 homes sold in July 2026, compared with 37 in July 2025.
Should I wait for newer figures before deciding?
City-level figures are published well after the month they describe, so waiting for them means acting on information that is already old. A citywide median is also a poor proxy for one address. Comparing your specific home, or your specific search criteria, against current local activity is the more useful step.
