Selling in a Falling Sydney Property Market – The Downsizer Dilemma

As the Sydney property market faces softer conditions, weaker auction clearance rates, longer selling periods and increasingly cautious buyers, an important question arises: Why would a homeowner choose to sell in a falling market?

There are generally two key reasons.

1. Selling and buying in the same market

For homeowners looking to upsize, a falling market is not necessarily a disadvantage.

While they may achieve a lower price for their existing property than they would have 12 months ago, they are also buying into the same softer market.

For upsizers in particular, this can present an opportunity. A 10% reduction on a $5 million property represents a $500,000 saving, compared with a $300,000 reduction on a $3 million property.

Assuming both properties decline by the same percentage, the upsizer could be approximately $200,000 better off on the changeover, before transaction costs.

Selling and buying in the same declining market can therefore work in an upsizer's favour, as the dollar saving on the more expensive property can outweigh the reduction in the value of their existing home.

By contrast, the same market conditions can work against downsizers, who stand to lose more on the sale of their higher-value home than they save on their next purchase.

2. Financial pressure – selling because they have to

The second reason is far less discretionary – financial stress.

Higher mortgage repayments, increased holding costs and broader cost-of-living pressures can leave some homeowners with little choice but to sell.

These vendors are often more motivated, particularly when their property has been sitting on the market without sufficient buyer interest.

As clearance rates weaken and selling periods lengthen, buyers gain greater negotiating power. Vendors who need to sell may ultimately have to accept prices well below their original expectations.

Of course, life events such as relocation, separation and deceased estates will always bring properties to market, regardless of prevailing conditions.

The Downsizer Dilemma – A Domino Effect on Sydney's Housing Supply

One of the less-discussed consequences of a falling market is the reluctance of downsizers to sell.

Unlike upsizers, downsizers generally have more to lose financially by selling a higher-value property and purchasing a less expensive one in the same declining market.

Rather than accept a lower sale price, some are choosing to remain in their existing homes or retain them as rental investments while waiting for market conditions to improve.

This reluctance to sell has a significant knock-on effect on Sydney's housing supply.

Larger family homes that would ordinarily be released onto the market remain tightly held, reducing the availability of quality properties for families looking to upsize.

In turn, those families delay selling their existing homes because they cannot find a suitable property to purchase.

The result is a domino effect across the property market. One homeowner's decision not to sell can prevent the next transaction from taking place, restricting the flow of housing stock across multiple price brackets.

This creates a shortage of quality housing stock, even in a softer market, particularly in Sydney's established and tightly held suburbs.

The Flow-On Effect – Increasing Supply in Sydney's Prestige Rental Market

At the prestige end of Sydney's property market, we are seeing a growing number of owners choosing to defer selling until market conditions improve, instead placing their properties on the rental market.

While this decision removes properties from the sales market, it is contributing to an increase in the supply of prestige and furnished executive rental properties.

The result is an interesting market imbalance – a shortage of quality properties for sale, alongside increasing competition in the prestige rental market. With a relatively small and selective pool of prospective tenants, greater choice is placing downward pressure on rental expectations and increasing the importance of competitive pricing.

This is particularly relevant as we approach the traditionally quieter Christmas and New Year period, when tenant enquiry levels can soften and vacancy periods may extend.

For owners considering renting out their former principal residence, it is also important to obtain appropriate tax advice, as the decision may have capital gains tax implications when the property is eventually sold and land tax implications.

At SydneySlice Executive Rentals, our focus is on maximising rental returns while minimising vacancy through accurate market pricing, targeted marketing and careful tenant selection.

What Does This Mean for the Sydney Market?

Sydney is not one uniform property market. Conditions vary significantly between suburbs, price brackets and property types.

A falling market does not necessarily mean an abundance of properties for buyers to choose from. In fact, we can see the seemingly contradictory situation of weakening clearance rates and longer selling periods occurring alongside a shortage of desirable family homes.

The issue is not simply how much stock is available, but the quality of that stock and the motivation of the vendors behind it.

For owners of well-located, quality homes in tightly held suburbs, limited competing stock can still work in their favour. Even in a softer market, a well-presented and realistically priced property can attract strong buyer interest when suitable alternatives are scarce.

As discretionary sellers withdraw from the market, the distinction between vendors who want to sell and those who need to sell becomes increasingly important.

For buyers, understanding a vendor's motivation can be just as valuable as understanding the property's market value. The greatest buying opportunities often arise when a motivated vendor meets a well-informed, financially prepared buyer.

At SydneySlice, identifying these opportunities, understanding vendor circumstances and negotiating strategically are central to achieving the best possible outcome for our clients, particularly in a softer market.
