What Days on Market Reveal About a Suburb Before You Buy

You have found a suburb you like, the listing photos look fine, and the agent says homes there "move quickly". Then you open a property portal and see that the median days on market for the area is 41. Is that quick? Slow? Normal for the time of year? Most buyers glance at the number, feel vaguely reassured or vaguely worried, and move on without learning anything from it.

That is a waste, because days on market is one of the few suburb statistics that tells you about the people around you rather than the bricks. It measures how keen other buyers are, how realistic local sellers have been, and how much room you might have when you make an offer. Read on its own it misleads. Read alongside two or three other figures, it becomes one of the most useful ten minutes of research you can do before committing to a street.

What the number actually counts

Days on market is the gap between the day a home is first advertised and the day a sale is agreed. Portals usually publish the median for a suburb over the last twelve months, split by houses and units. The median matters because a single mansion that sat for 200 days would drag an average upward, while the middle sale stays put.

Here is the first catch. Most portals count from the date of the current listing, not the first one. If a seller withdraws a home after 60 quiet days and relists it a fortnight later with new photos and a lower price, the counter starts again at zero. That home will eventually sell at "day 19", and the suburb median will look healthier than the street really is.

I first noticed this while building a small spreadsheet of sales in two neighbouring suburbs. In one of them, 7 of the 52 houses sold over the year had been listed before under a different advertisement. Once I added their earlier days back in, the median rose from 33 to 39. Not dramatic, but enough to change how I would have negotiated.

Why a fast suburb is not automatically a good one

The common advice is simple: low days on market means strong demand, so buy there before it gets dearer. I disagree with the "automatically" part. Speed has several possible causes, and only one of them is good news for you.

Homes can sell fast because lots of people want to live there. They can also sell fast because they were underpriced to start a bidding contest, which is a selling tactic rather than a sign of the suburb. And in places where most homes go to auction, the campaign length is fixed, often four or five weeks, so days on market barely moves whatever demand does. A suburb where 80 percent of sales are auctions will show a tidy, steady figure that tells you almost nothing.

The opposite is also true. A suburb with a median of 70 days might have a quiet, stable population where homes simply change hands less often, with sellers who are in no hurry. Slow can mean patient rather than unwanted.

The number is a symptom. Before you react to it, find out which of the possible causes is behind it.

The three figures to read alongside it

Vendor discount

This is the difference between the first advertised price and the final sale price, shown as a percentage. Some portals publish it directly. A suburb with long days on market and a discount of around 6 or 7 percent is telling you sellers began too high and buyers waited them out. Long days with a discount under 2 percent suggests a slow but firm market, where waiting will not save you much.

Number of sales

Check how many sales the median is based on. A suburb with 14 house sales in a year can swing by three weeks because of two unusual homes. Under roughly 30 sales, I treat the figure as a hint, not a measurement, and I look at the suburb next door to see if it agrees.

The trend, not the snapshot

One median is a photo. Three or four quarters in a row is a film. If days on market has gone from 28 to 35 to 44 over three quarters, the suburb is cooling, and you can probably negotiate harder than the agent suggests. If it went the other way, expect competition and set your limit before you arrive at an open home.

Putting it together: a worked comparison

Here is how the readings combine, using the kind of figures you will find for real suburbs on any major portal. Suburb names are left out on purpose, because the pattern matters more than the place.

That last row is the one that catches people out. A short median with a big discount rarely happens naturally. Usually it means homes sat, got pulled, came back cheaper and then sold quickly on their second run.

Seasons matter too. Across most markets I have looked at, winter medians run noticeably longer than spring ones, sometimes by ten days or more. Compare the same quarter year on year rather than this month with last month.

What it says about the street, not just the suburb

A suburb median hides a lot. One part of a postcode can back onto a park and the other onto a freight line. Once the suburb figure looks reasonable, scroll the sold listings and pick out the homes within a few blocks of the one you like. If those took twice as long as the suburb median, something about that pocket is putting buyers off, and you should go and find out what before you make an offer. Noise, a steep hill, a busy school drop-off and flood mapping are the usual suspects. Our guide on reading a neighbourhood before you make an offer covers how to check those on foot.

The reverse is just as useful. If homes on one particular street sold in under three weeks while the suburb took six, that street has something people value. You will pay for it, but you will probably get it back when you sell.

Limits worth admitting

I cannot tell you a "good" number, because it depends on the city, the price band and the year. A 45-day median would be sluggish in a hot inner suburb and brisk in a regional town. Private sales that never reach a portal are missing from the figures entirely, and in some areas that is a meaningful share. Treat days on market as a reason to ask questions, not as an answer.

When you speak to the agent, those questions get sharper. Ask how long the specific home has been on the market in total, including any earlier listing. Ask what the last three comparable homes nearby sold for and how long each took. A good agent will answer straight away. Our list of questions worth asking before you make an offer has more along these lines.

One thing to do this week

Pick the suburb you are most serious about and one neighbour on each side. For each, write down four things from the last twelve months: median days on market for houses, the number of sales behind it, the vendor discount, and the same median for the year before. It takes about fifteen minutes on a portal. If the three suburbs tell different stories, you have just found the place where you have the most bargaining power, and you can browse more of our neighbourhood guides before you go and look at it in person.
