If you want one answer: April, with a listing that goes live in late February or March so it is under contract by the time the spring flood of competing homes arrives. That answer comes with real caveats, and the caveats are where the useful part lives. The national research and the Denver-specific data do not point at exactly the same month, Denver’s snowiest month is March rather than January, and the month that is best for price is not the month with the most buyers walking through the door. Most sellers do not actually get to choose their month anyway — a job, a school year or a purchase on the other side sets the date. So rather than a single number, here is what the evidence actually supports, month by month, and how to work backward from whatever date you are stuck with.
- Best price execution: April, on a listing that launched in late February or March
- Most buyer traffic: May and June
- Most competition from other sellers: July and August
- Weakest nationally: September and October
- Fewest rival listings: December and January
What the national research says
ATTOM Data Solutions analyzes more than 52 million single-family and condo sales from 2015 through 2025 to calculate a “seller premium” — how much the sale price exceeded the automated valuation at the time of sale. In its 2026 analysis, March ranked first at a 10.7 percent premium, followed by May and April at 10.2 percent, then February and June at 10.0 percent. October ranked last at 7.9 percent, with September just above it at 8.0 percent. Note carefully what that measures: the month a sale closed, not the month it was listed. A March closing generally implies a January or February listing. That is why the practical advice runs about a month ahead of the ranking. The National Association of Realtors adds the volume picture. Nationally, sales peak from April through June, with June exceeding 18,000 existing homes sold per day against roughly 11,380 in the December-through-February trough. Median days on market runs about 30 at peak season and stretches to 49 in winter. NAR also makes a point worth holding onto: the West is the region least affected by seasonality. Denver’s swing is milder than Chicago’s or Boston’s.
What Denver’s own numbers show
The cleanest Denver-specific evidence is the close-price-to-list-price ratio, which the Denver Metro Association of Realtors publishes in its monthly market trends reports and measures the same way each time. Across the most recent cycle it ran 98.23 percent in December, 97.94 in January, 98.70 in February, 99.13 in March, and peaked at 99.44 percent in April, settling back to around 99.0 by July. That is a spread of 1.50 percentage points between the January low and the April high. On a $605,000 home — the metro median in July 2026 — that difference works out to roughly $9,000. It is a single year rather than a long-run average, so treat it as indicative rather than a law of nature, but it is the most direct Denver answer available. The inventory cycle explains why. New listings jumped more than 150 percent from December to January, rose another 12 percent in February and nearly 20 percent in March to 5,986, and peaked in April at 6,642 before declining every month after. Active listings, meanwhile, climbed steadily all year, from 8,228 at the end of January to 13,115 in July. Read those two series together and the strategy falls out. Buyer demand builds through spring while the accumulated pile of unsold homes is still small. By July and August, buyers have the most options they will have all year — which is exactly when a seller has the most competition. July’s median of 21 days in the MLS was the slowest reading of the year, against 14 in April. DMAR’s own long-run averages confirm the rhythm: active listings decline an average of 18.4 percent from November to December, are essentially flat from January to February, and rise an average of 11.3 percent from February to March.
The Denver-specific complications
March is the snowiest month. This surprises people every year. Per the National Weather Service’s Denver snowfall records going back to 1882, normal March snowfall is 11.4 inches — more than any other month, with April second at 8.7 inches. A March listing is exposed to a spring storm that can flatten a weekend of showings and make exterior photos look wrong for the season. Shoot your photos before the listing goes live, and shoot them in whatever good weather you get. The school calendar sets the summer window. Jeffco Public Schools starts August 19 in 2026 and Denver Public Schools begins the following week. A family that wants to be settled before the first day needs to close in early August, which means going under contract in June and listing in May. That is a large, motivated, deadline-driven slice of the buyer pool, and it is the practical reason May and June are, as DMAR’s own market trends chair put it, typically the busiest two months of the year. Winter is not the disaster people assume, but it is not secretly better either. Nationally, ATTOM ranks December seventh of twelve at a 9.1 percent premium — ahead of every summer and fall month — and January sixth. And a January seller in Denver faces far fewer rival listings than a July seller. But Denver’s January close-to-list ratio was the year’s worst, so the thin competition is offset by thin demand. Winter suits a distinctive property with a narrow, motivated buyer pool. It is not a general strategy.
How to work backward from your date
Most sellers are choosing among a handful of feasible months, not all twelve. The sequence is the same regardless: Work back from your target live date. Cosmetic work — paint, flooring, decluttering, minor repairs — wants four to six weeks. Anything permitted, or a roof, or an HVAC replacement, wants considerably more, and contractors are booked hardest in exactly the spring window everyone is aiming for. Exterior painting and landscaping are weather-dependent here and unreliable from November through April, which is a real argument for doing that work in the fall before a spring listing rather than trying to squeeze it in during March. Then hold the price honest. Seasonality is worth a percentage point or two; overpricing at launch costs several. If you are still deciding whether this is your year at all, is now a good time to sell in Denver covers that side, and the home sale calculator will give you a rough net at different price points.
Frequently Asked Questions
So should I wait until spring if it is currently October?
Only if waiting is genuinely free. Five months of carrying costs, an extra mortgage payment cycle and the risk that rates or inventory move against you can easily exceed the one to two percent seasonality is worth. If you need to sell, price it correctly and sell.
Is December really that bad in Denver?
It is the thinnest month for activity, but it is not the worst month for price. Inventory drops sharply, so a well-presented home has unusually little competition. The buyers who are out in December tend to be serious, often relocating with a start date.
Why does April beat March in Denver if March wins nationally?
Because the national ranking measures closings and the Denver ratio measures the same thing at the point of sale, roughly a month apart. They are consistent, not contradictory: list in late February or March, close in April.
Does the best month change by neighborhood or price point?
Yes, more than most sellers expect. Luxury and foothills properties are less seasonal and more buyer-specific. Family-sized homes in strong school attendance areas are the most seasonal of all, because that buyer is working against an August deadline.
What about listing in July or August?
Workable, but understand that you are entering the market at peak inventory. Denver active listings in July were roughly 60 percent above the January level. You need sharper pricing and better presentation in August than you would have needed in April for the same result.
How far ahead should I start planning?
Three to four months before your target listing date for anything involving contractors, and six weeks for a cosmetic-only refresh.
