I pulled Winnetka's seller numbers for this piece, straight from MRED InfoSparks, as of late August 2026. They tell a clear story. Well-priced homes are moving fast, sellers are closing at or above asking more often than not, and inventory is tighter than it's been in a year. If you've been sitting on the fence about listing this fall, here's what's actually happening.
Where Winnetka's Market Stands Right Now
These are the current numbers, average and median side by side, each compared to a year ago.
Metric | Average | Median |
|---|---|---|
Sale Price | $2,400,597 (up 7.4% year over year) | $1,997,500 (up 16.1% year over year) |
Days on Market | 35 days (down 37.5% year over year) | 7 days (flat year over year) |
Sale-to-List Ratio | 103.5% (up 0.5% year over year) | 101.9% (up 1.7% year over year) |
Months of supply is sitting at 1.3, down 18.8 percent from a year ago. Source: MRED InfoSparks, data as of late August 2026.
What the Gap Between Average and Median Days on Market Tells You
A 7-day median against a 35-day average is not a contradiction. It means most well-priced Winnetka listings are gone within a week, while a smaller number of homes, usually priced wrong, positioned oddly, or needing work, sit much longer and pull the average up. If your home is priced to the current market, the median is closer to what you should actually expect. If it's not, you're looking at the average or worse.
Why a Sale-to-List Ratio Above 100 Percent Matters
Both the average and median sale-to-list ratios are above 100 percent right now, which means the typical Winnetka home is closing above its original list price, not just meeting it. That's not universal. It happens on homes priced realistically from the start, where multiple buyers end up competing for the same listing. It doesn't happen on homes that get overpriced and then sit.
Should You List This Fall?
I'm not going to tell you the market is about to get better or worse, because nobody actually knows that, and anyone who tells you otherwise is guessing. What I can tell you is what's true right now. Inventory is tight, at 1.3 months of supply, well below what most people would call a balanced market, and down almost 19 percent from a year ago. If your situation already has you thinking about a move, whether that's downsizing, relocating, or something else, this is a genuinely strong environment to be a seller in. If you're not ready, that's fine too. I'd rather give you the real numbers than rush you into a decision.

Should I wait until spring to sell, or list now?
That depends on your own timeline more than the calendar. What I can tell you is that right now, well-priced Winnetka homes are moving quickly and closing above asking, with inventory tighter than it's been in a year. If you're already thinking about a move, this is a strong moment to be a seller. If your circumstances point to waiting, the data here will still be useful context when you're ready.
