The best time of year to sell a house in Northfield
We ran every Northfield house that went under contract from January 2023 through September 2026 and closed — 249 of them — and sorted the results by when each one was listed. Northfield is too small to name a single best month with confidence, so we grouped the months into seasons. Houses listed from December through May did better than those listed from June through November.

The answer
December through May, ahead of summer and autumn
249 Northfield single-family detached homes that went under contract between January 2023 and September 2026 and closed, grouped by the season they were listed. Listings per season: winter (December–February) 48 · spring (March–May) 90 · summer (June–August) 71 · autumn (September–November) 39. Source: MRED.
Chart one
What you get for your house, by the season you list it
Median sale price as a percentage of asking price, grouped by listing season. The scale starts at 90% so the differences are visible.
Winter and spring listings both closed at a median of exactly 100.0% of asking, summer listings at 98.3% and autumn listings at 98.4%. On a $1,075,000 list price, the median in this study, the observed December–May and June–November median sale-to-list ratios differ by roughly $18,000. That does not mean listing the same house in spring would make it sell for $18,000 more: the seasons contain different homes.

Chart two
How fast it goes, by the season you list it
Median days from listing to accepted offer.
These are medians, and the median hides a long tail: across the whole period about half of Northfield houses (51%) went under contract within eight days, but about one in four took more than three weeks and about one in twelve took more than two months. Winter listings moved fastest, with a median of six days and 63% under contract within eight days. Among autumn listings, 13% took more than two months. A median of a week does not mean your house sells in a week — it means half of them do.

When buyers actually sign
How many houses were available each month, how many went under contract, and how many showings each listing drew.

| February | 13.7 | 5.3 | 7.1 |
| March | 16.7 | 6.0 | 6.6 |

In a typical year, about 14 to 17 detached Northfield houses were available each month from January through March, rising to about 29 in May and staying at about 22 to 26 from June through September before falling to about 11 in December. Contracts peaked in May and June, about 8 a month, roughly a third of the houses available, and there was a smaller rise in September, about 7. They fell to about 5 a month in July and August, when about 22 to 24 houses were available, and to 2 or 3 in November and December. Showings per listing were highest in January and February, about 7, when the fewest houses were on the market, and ran about 4 to 6.5 for the rest of the year, lowest in December.
In Northfield, winter and spring listings did best in the study above, and the chart shows why that is plausible: buyers were active and choices were thin from January through spring, while July and August brought more houses for sale and fewer contracts.
Monthly averages for 2023, 2024 and 2025, detached houses. Homes available during the month: houses for sale at the end of the previous month plus new listings that month (MRED via InfoSparks), so each house counts once whether it went under contract, stayed on the market or was withdrawn. Under contract: MRED closed and pending sales by contract month. Showings per listing: MRED via InfoSparks; showing data comes from ShowingTime and counts only showings scheduled through ShowingTime.
What it means
Where the seasons differed
The clearest difference was in how often houses sold below asking: about two in five December–May listings, against nearly three in five June–November listings. Spring listings had the fewest, 37%. At the top, the 75th percentile sale-to-list was 103.1% for December–May listings and 101.6% for June–November listings, so bidding above asking was more common in winter and spring.
The pattern held across price levels: split into lower and upper halves by list price (the split falls at $1,075,000), December–May listings had the higher median sale-to-list in both, and the gap was widest in the lower half, where 30% of December–May listings sold below asking against 61% of June–November listings. Summer and autumn listings also had lower median asking prices, about $949,000 and $849,000, than winter and spring listings, about $1.13 million and $1.23 million, so part of the difference reflects which houses were listed when.
Within summer, most of the weakness came from August listings, which closed at a median 95.9% of asking, with about three in four selling below asking; June and July listings together closed at 99.5%. December–May listings had the higher median in 2023, 2024 and 2025. In 2026 so far the order has reversed, with June–September listings at a median 100.4%, but the year is not complete and only listings that have closed are counted.
Why that is, this data cannot tell us. Plausible reasons — buyers aiming to move before the school year, sellers bringing well-prepared houses out in spring — are guesses, and we would rather say so than dress one up as a finding.
In this data, about two in five Northfield houses listed from December through May sold below asking. Among June–November listings it was nearly three in five.
138 December–May listings and 111 June–November listings across nearly four years. The difference held in each full year, 2023–2025. An observed pattern, not a rule.
Important caveats
What this does not mean
- It does not mean wait. Northfield averages about five or six detached listings that go on to sell each month. The right buyer for a particular house can appear in any season, and if you need to move in August, move in August. The seasonal difference in this data is not a reason to hold a house off the market for months.
- Winter and spring work best when the house is ready. December–May listings did better in this Northfield data, but timing alone does not overcome poor preparation or pricing. If spring is the target, preparation should start early enough for the house to be genuinely ready to launch.
- Small numbers. With 249 sales over nearly four years, a few unusual houses can move a season's figures. Single months are shown in the table for completeness, but several have too few listings to judge on their own.
Condominiums and townhouses
Spring and summer, for condominiums and townhouses
About a third of Northfield's sales are condominiums and townhouses, so we ran the same analysis on 121 of them. No month had 20 listings, so the results are grouped by season.
For attached homes the seasons split differently from detached houses. Listings from March through August closed at a median 100.0% of asking, and 63% went under contract within eight days; September–February listings closed at 98.4%, with about three in five selling below asking and a median of 12 days to contract. Autumn listings had the weakest observed results, and winter listings took longest. With about thirty listings a season, these are observed patterns, not rules.
For buyers
Read the same chart backwards
From the buyer's side, summer and autumn showed the clearest signal in this dataset: detached houses listed from June through November closed at a median 98.3% of asking, and 58% sold below their asking price. For condominiums and townhouses, autumn listings were the softest, with 64% selling below asking.
The trade-off is selection in late autumn and winter: in a typical November about 15 detached houses were available in all of Northfield, and in December about 11.
Thinking about a spring listing?
Preparing for a spring listing starts in winter. There is no cost to starting the conversation early.
