Days on Market Explained: The Demand Signal Most Property Investors Miss

Introduction: The Metric Hiding in Plain Sight

Ask most property investors what metrics they track and you'll hear the usual suspects: median price, rental yield, vacancy rate, maybe capital growth. But one of the most revealing indicators of a property market's health is often overlooked: days on market (DOM).

Days on market tells you how long properties take to sell in a given suburb. It's a real-time demand signal that moves faster than prices, reacts before yields shift, and can give you an early warning that a market is heating up — or cooling down — before most investors notice.

What Is Days on Market?

Days on market measures the number of days between a property being listed for sale and the date it goes under contract or is reported as sold.

It's typically expressed as a median or average for all sales in a suburb over a given period.

What DOM Actually Measures

At its core, DOM measures the imbalance between supply and demand:

• Low DOM (roughly under 30 days) = more buyers than available properties. Sellers often have the upper hand
• Moderate DOM (30–60 days) = a roughly balanced market
• High DOM (over 60 days) = properties are lingering, indicating softening demand or oversupply

These ranges vary by market type. In inner-city Melbourne, 20 days might be normal. In a rural town, 60 days could be perfectly healthy. Always compare a suburb's DOM to its own history and to similar suburbs.

Why DOM Is Such a Powerful Indicator

1. DOM Moves Before Prices

Price data is inherently lagging. By the time median price data reflects a market shift, the shift has already been underway for months. DOM reacts almost immediately to changes in buyer behaviour. If an interest rate cut sparks renewed buying activity, DOM will start falling within weeks. For investors, DOM serves as a leading indicator — giving you advance notice of market direction changes that won't show up in price data for another quarter or two.

2. DOM Reveals Buyer Competition

A suburb where DOM is falling suggests buyer competition is intensifying. More people are making offers, properties are selling faster, and sellers are becoming more confident. This often precedes price increases. Conversely, rising DOM suggests buyer urgency is declining and negotiating power is shifting toward buyers.

3. DOM Highlights Divergence Within a Market

At a city-wide level, the market might look stable. But suburb-by-suburb DOM reveals significant variation. Some suburbs may be clearing properties in 15 days while others sit at 70. This divergence tells you where demand is concentrating and where it's thinning out.

How Picki Tracks Days on Market

Picki tracks days on market at the suburb level using data stored in its hpc_dom dataset.

Data Collection

Picki monitors property listings and sales events across Australian suburbs. For each property that sells, the system records the number of days between the initial listing date and the date the property was reported as sold or under contract.

Aggregation Method

Rather than showing a single point-in-time number, Picki tracks DOM on a rolling monthly basis, pulling the most recent 12 months of data. The data is broken down by property category — houses are tracked separately from units and from “all” property types. This is important because houses and units in the same suburb can have very different selling speeds.

Why Rolling Data Matters

A single month's DOM figure can be volatile. By tracking DOM over a rolling 12-month window, Picki gives you a picture that's responsive to genuine trends while filtering out statistical noise.

How to Interpret DOM Data

Compare to the Suburb's Own History

The most useful comparison is a suburb versus itself over time. If a suburb typically clears properties in 30–35 days but current DOM has dropped to 18, something has changed — increased buyer demand, reduced listings, or both.

Compare to Neighbouring Suburbs

Relative DOM is also informative. If three target suburbs show DOM of 20, 42, and 65 days respectively, the first has the strongest buyer demand — but always use DOM alongside price, yield, vacancy, and demographic data.

Look at the Direction, Not Just the Level

A suburb with DOM of 40 days that has fallen from 60 is more interesting than one at 30 that has risen from 20. Direction of change indicates the market's momentum.

Consider Seasonal Patterns

DOM tends to be lower in spring and higher in mid-summer. Comparing to the same period last year gives a more reliable signal.

DOM in the Context of Other Metrics

DOM + Vacancy Rate

Low DOM + low vacancy = a tight market with strong demand from both buyers and renters. A positive signal for investors.

DOM + Price Trends

Falling DOM + rising prices = a classic growth market. Rising DOM + rising prices may be a late-cycle signal. Rising DOM + falling prices = a market in correction.

DOM + Rental Yield

Low DOM + high yield is the rare combination that excites investors — strong demand and strong income. High DOM + high yield may indicate a “yield trap” where the discount reflects genuine risk.

DOM + New Supply

Rising DOM in a suburb with significant new housing supply may simply reflect increased competition from new stock, not necessarily falling demand.

Common Mistakes When Using DOM

• Looking at a single month — always examine 6–12 months to identify genuine patterns
• Comparing incomparable suburbs — compare like with like (same city, price bracket, property type)
• Ignoring listing method — auction campaigns have defined timelines that affect DOM differently from private treaty sales
• Treating low DOM as always good — very low DOM can indicate an overheated, FOMO-driven market

Key Takeaways

• Days on market measures how quickly properties sell — a direct signal of buyer demand relative to supply
• DOM moves before prices, making it one of the best leading indicators of market direction
• Picki tracks DOM at the suburb level using rolling monthly data from the hpc_dom dataset, broken down by property category
• Always compare DOM to the suburb's own history and to similar suburbs, not arbitrary benchmarks
• Direction of change is often more informative than the absolute number
• Combine DOM with vacancy rates, price trends, yield, and supply data for a complete picture
• Beware common pitfalls: single-month snapshots, cross-market comparisons, and assuming low DOM is always positive
