What the numbers say
Northfield this month, in plain terms
Is Northfield a seller's market or a buyer's market?
A seller's market. At September's pace it would take about 1.8 months to sell every detached house listed in Northfield. Under four months generally favors sellers; above six favors buyers. Since 2021, supply has stayed between about half a month and five months, and fewer houses are coming to market: owners listed 97 detached houses in the last twelve months, against 107 the year before. At the end of September there were 10 detached houses for sale. Between 2016 and 2019, Northfield typically carried between about five and eleven months of supply.
Are prices going up?
Not over the last year. The twelve-month median for a detached Northfield house was $1,202,500 in September 2026, against $1,275,000 a year earlier, about 6% lower. Treat that with care: with about seventy detached sales a year, the median moves in steps. It reached $1,362,000 in June 2026 before easing back, and calendar 2025's median ($1,180,000) was about 18% above 2024's ($997,500). It describes what sold; it does not mean any particular Northfield house lost or gained value. The longer direction is clear: the same measure was $679,822 in September 2019 and first passed $1 million in late 2022.
How fast are houses selling?
Over the twelve months to September, the median Northfield house went under contract six days after listing, against nine a year earlier, and sold for 100% of its last asking price. It took an average of ten showings to reach a contract. Our own analysis of 249 Northfield houses that went under contract between January 2023 and September 2026 found that about half (51%) did so within eight days, but about one in four took more than three weeks and about one in twelve took more than two months. A quick median does not guarantee a quick sale.
What does this mean if you're selling?
Low supply helps, but price to the most comparable recent sales near yours, not to the village median. A Northfield median mixes very different houses, from mid-century homes to newer and larger houses on big lots. Timing showed up in our 2023–2026 analysis: houses listed from December through May had stronger observed results than those listed from June through November. See the Northfield timing study.
What does this mean if you're buying?
Expect few choices at any moment: ten detached houses at the end of September. Be ready before the right one appears, with financing in place, a clear sense of value, and an eye on Coming Soon listings that show up before they're active. Condominiums and townhouses are about a third of Northfield's sales and behave differently; they have their own figures below.
Coming Soon & Private Exclusives
Before homes reach the active market
Not every Northfield sale starts as an active listing. Coming Soon homes are marketed before their broader public-market launch, giving buyers an earlier opportunity to learn about a property. Buyers can express interest and make offers during this stage; whether a seller considers an offer before the broader launch is up to the seller. Compass Private Exclusives are not publicly marketed while they are offered as Private Exclusives; some later come to the open market. Neither guarantees access to a particular home.
This year vs. a typical year
Is 2026 running hotter or cooler than usual?
Each month of 2026 so far, set against the same month’s average for 2023 to 2025. When a bigger share of the available houses goes under contract than usual, buyers are outpacing supply.

Through September, 2026 has had fewer Northfield houses to choose from than a typical year, but about the usual number of contracts. From January through September, 83 detached houses came to market, against a typical 92 for those months, and 55 went under contract, against a typical 56. Because the pool was smaller, the number that went under contract was a larger share of the houses available than is typical in every one of the nine months. The widest gap came in January, when 5 of 9 available houses went under contract (56%, against a typical 31%). Showings per listing ran above typical in January, June and July and below it in the other six months, so buyers did not need more showings per house to keep signing at the usual pace. Northfield's monthly numbers are small, four to seven contracts a month in 2026, so read the pattern across the year rather than any one month.

How many houses come to market each month, with a clear spring peak in May. The last twelve months brought 97 new listings, down from 107.
Condominiums and townhouses
The attached market, twelve months to September 2026
About a third of Northfield sales are condominiums and townhouses (35 of 103 over these twelve months). They sell at very different prices from detached houses, so they get their own figures.

Calendar 2025
Where the sales happened
Every closed sale of a house, condominium or townhouse in Northfield in 2025. Mobile homes and vacant land excluded. Refreshed each January.
97 sales in all: 67 detached houses (median $1,180,000) and 30 condominiums and townhouses (median $357,500). Every sale under $500,000 was a condominium or townhouse; detached sales ran from about $500,000 to $5 million, with the most between $500,000 and $1 million.

Age of homes sold
When the houses that sold were built
Detached houses sold in the twelve months to September 2026, by the decade they were built.
About half of the houses that sold were built in the 1950s and 1960s (35 of 66), and the 1950s alone account for 20, more than any other decade. That fits the village's history: Northfield grew quickly in the 1950s. Only seven were built between 1970 and 1999, and eleven in 2000 or later. Year built describes when a house was first constructed; it says little about its condition, renovations, additions or how it compares with any other house.
Year built as recorded in the MLS listing. 2 detached sales listed the year as unknown and are excluded. A house rebuilt on an older lot shows its new construction year. Source: MRED closed sales, October 2025–September 2026. Refreshed monthly.

Method
How these numbers are calculated
- Source. MRED, the multiple listing service for northern Illinois, via its InfoSparks reporting tool.
- What's counted. Single-family detached houses in Northfield unless a figure says otherwise. Condominiums and townhouses have their own section, and the calendar-2025 price bands include them. Mobile homes and vacant land are left out.
- Twelve-month figures. Price and showings use a rolling twelve months, so a few unusual sales in one month don't swing the picture.
- Small numbers. Northfield has about seventy detached sales a year, so figures can move more from month to month than in larger towns. We describe patterns over several months rather than single months.
- Year built. The age-of-homes section uses the year built recorded in each MLS listing; listings marked unknown are left out.
- Median first. The median is the middle sale. We show it ahead of the average, which a few very large sales can pull up.
- New construction. A detached house marked as new construction in the MLS listing. Shown as its own segment, with a median only when there are at least five sales, and never compared with older homes.
- This year vs. a typical year. Each month of the current year is compared with the average of the same month in the last three full years. “Homes available” is the houses for sale at the end of the previous month plus that month’s new listings, so each house counts once whether it went under contract, stayed on the market or was withdrawn.
- Updates. The text and figures are refreshed monthly. The live charts update themselves and may show a newer month than the text.
