Home loan clients chasing more space in prestige postcodes are facing eye‑watering premiums for an extra bedroom, fresh PropTrack data shows.
This comes on top of strong national price growth. Nationally, dwelling values have already climbed 9.9% over the past year to around $900,000, according to NAB’s latest Housing Monitor.
In Sydney’s Vaucluse, the median price gap between three- and four-bedroom houses is $3.79 million, with four-bedders at about $8.34 million versus $4.55 million for three-bedroom homes. Rose Bay is not far behind with a $2.83 million difference, while Melbourne’s blue‑chip Toorak and Armadale suburbs show gaps of $2.675 million and $2.59 million respectively.
REA Group Senior Economist Eleanor Creagh said these premiums reflect more than an extra room.
“Once you are in prestige markets, the ‘extra bedroom’ is rarely just an extra bedroom,” Creagh said. “It is usually bundled with a bigger block, a wider frontage, a superior floorplan, more bathrooms, more parking, a pool, better entertaining space, and often a more tightly held location within the suburb.”
With mortgage rates higher and assessments tighter, Canstar estimates that a single borrower on the average full‑time wage can now borrow about $24,800 less than before the February and March RBA cash rate hikes, underscoring the squeeze on borrowing capacity at higher price points.
The pattern extends to apartments in affluent harbourside and beachside pockets. Elizabeth Bay three-bedroom units carry a median price $2.61 million above comparable two‑bedroom stock, with sizeable gaps also recorded in Pyrmont and Kirribilli.
“In prestige unit markets, the jump from two to three bedrooms often means moving from an ordinary apartment into a very different product,” Creagh said, pointing to higher levels, harbourside positioning, and larger internal areas.
These segments are often dominated by downsizers with substantial equity, meaning brokers may be structuring lower‑LVR loans but at significantly higher ticket sizes.
At the other end of the spectrum, the cost of upsizing by a bedroom is far more modest in more attainable markets such as Penrith, Frankston, and Logan Central, where the step‑up ranges from about $40,000 to just over $100,000.
Creagh noted that “Today, the preference for space has not disappeared, but it is being filtered through affordability constraints, and higher mortgage rates.” For first-home buyers and middle‑ring families, these locations may offer a more achievable upgrade path, giving brokers scope to tailor strategies that balance space, serviceability, and long‑term flexibility.
