Six offers in one weekend. That's what my neighbour got when she listed her three-bedroom semi a couple of springs ago. She'd priced it at what she thought was optimistic. It went $40,000 over asking, with no inspection condition, and the buyer waived the appraisal. Eighteen months later, a nearly identical house two streets over sat for 71 days and closed $22,000 under list — after the seller paid for a new roof and covered part of the buyer's closing costs.
Same street. Same school district. Same house, basically. Completely different game. That gap between those two sales is the whole story of a buyer's market versus a seller's market, and if you can't read which one you're in, you'll either overpay or leave money on the table. Usually both, in the wrong order.
So how do you actually tell? Not with gut feelings, not with the headline you saw on the news, and definitely not with what your cousin's agent told you. You read the numbers. Here's how.
Key Takeaways
- Months of inventory is the single clearest indicator: under 4 months favours sellers, over 6 favours buyers.
- Days on market tells you the temperature faster than price data, which lags by weeks.
- The 3-3-3 rule is a rough memory trick, not a law — useful for orientation, dangerous if you treat it as gospel.
- Sale-to-list ratio above 100% means buyers are competing; below 97% means sellers are conceding.
- National headlines are nearly useless. Your submarket can run opposite to the country.
- The hardest months to sell are usually late autumn and mid-winter, but that's a trend, not a guarantee.
The clearest signs of a buyer's market vs a seller's market
Most explanations start with supply and demand. Fine, but that's abstract. You can't measure "demand" on a Tuesday afternoon. You can measure how long homes sit and how much inventory is piled up. That's where the real signal lives.
Months of inventory: the metric that settles most arguments
Months of inventory answers a simple question: at the current pace of sales, how long would it take to sell every home currently listed?
- Under 4 months — seller's market. Buyers outnumber listings, and you'll see competition, escalation clauses, waived contingencies.
- 4 to 6 months — balanced. Neither side holds a strong hand.
- Over 6 months — buyer's market. Sellers are chasing the market down, and concessions come back into fashion.
I'll be honest: for years I ignored this metric because it felt academic. Then I watched a client insist on a 2% price reduction in what was clearly a seller's market. He lost three homes in a row before he believed me. The inventory number would have told him in ten seconds what three rejected offers taught him over two months.
Days on market: how many days signals a shift
You asked how many days on market is considered a buyer's market, and it's a fair question with an annoying answer: it depends on your local baseline. There's no universal number. A normal DOM in a slow rural county might be 90 days; in a dense urban core it could be 12.
The trick is to compare against your own market's recent history, not against a national figure. If homes in your area typically sold in 20 days last year and now take 45, the shift is real regardless of what the absolute number is. As a rough guide, when DOM runs 30% or more above the local norm for two consecutive months, you're drifting toward buyer's territory.
| Indicator | Seller's market | Balanced | Buyer's market |
|---|---|---|---|
| Months of inventory | Under 4 | 4–6 | Over 6 |
| Days on market vs norm | Well below | At norm | 30%+ above |
| Sale-to-list ratio | Above 100% | 97–100% | Below 97% |
| Inspection contingencies | Rarely accepted | Sometimes | Routinely demanded |
| Seller concessions | Almost never | Occasional | Common |
What is the 3-3-3 rule in real estate?
The 3-3-3 rule is a shorthand some agents use to judge whether a listing is priced right: a home should sell within 3 weeks, attract at least 3 serious offers, and be within 3% of the asking price. When all three hold, the market is hot and the pricing was accurate.
It's a decent conversation starter and a terrible decision-making tool. Here's my issue with it: those three thresholds were never calibrated to anything. In a genuinely slow market, a well-priced home might get one offer in six weeks — and that's a success, not a failure. Treating the 3-3-3 as a benchmark leads sellers to cut prices they shouldn't cut.
Use it as a smell test. If you're getting 12 showings and zero offers in three weeks, the price is the problem. If you're getting almost no showings at all, the problem is the listing itself — photos, description, or visibility.
The seasonality nobody warns you about
Which month is hardest to sell? The pattern most markets follow: December and January are the cruellest, with late August close behind as families disappear into the school-year transition.
But I want to push back on the usual advice here, because I've seen it backfire. Everyone knows spring is the busiest season, so everyone lists in spring. More buyers show up, yes — but so do your four closest competitors on the same street. In a balanced market, that competition can cost you more than the seasonal demand gains you.
I sold a property in early February a few years back. Fewer buyers, but mine was the only comparable listing in the area. It went in nine days. The March listing next door took twice as long and closed lower. Seasonality is a tendency, not a rule.
Why national headlines won't tell you anything useful
A national housing report is an average of wildly different realities. You can have a metro core in a full seller's market and a commuter belt 40 minutes away sitting in a buyer's market, both inside the same headline number.
Buyer's or seller's market by zip code
This is the part people skip, and it's the part that matters most. Inventory, days on market, and sale-to-list ratios vary enormously between zip codes — and sometimes between subdivisions in the same zip.
What I do: pull the last 90 days of sold comparables in a half-mile radius, then check active listings in the same zone. If there are 14 active listings and only 3 sold last month, that's roughly a four-and-a-half-month supply. That single calculation beats any national index for actual decision-making.
Your agent can pull this in minutes. If they can't, or if they answer with a national stat, that's information too.
Can a seller just ignore an offer?
Legally, in most jurisdictions, yes — a listing is an invitation to treat, not a binding commitment to respond. A seller can decline to reply, counter, or reject outright. There's no legal obligation to acknowledge an offer.
Practically, it's almost always a mistake. Ignoring an offer costs you information: you learn nothing about what buyers think your home is worth. And in a buyer's market, where serious offers are scarce, silence is expensive. I've watched sellers sit on a reasonable offer for a week hoping for better, only to see the buyer walk and the listing age another 30 days.
In a seller's market, ignoring a lowball offer is defensible. In a buyer's market, it's usually just pride.
What to actually do with all this
Check three numbers before you make any decision: months of inventory in your submarket, days on market versus the local norm, and the sale-to-list ratio over the last quarter. Those three will tell you which side of the table has leverage, and roughly how much.
Everything else — the season, the headline, the rule of thumb you read somewhere — is noise until those numbers agree with it.
And the thing I keep coming back to: the market doesn't care what you need. It only cares what the supply and the buyers are doing this month. Read that, and you'll be fine. Guess at it, and you'll be the person writing the angry post about how their house sat for 71 days.
