Buying in Portsea (2026): Australia’s Richest Suburb, and How to Finance a Home There
Portsea just became Australia’s richest suburb. Buying here is a prestige purchase, and the lending reflects it.
- Portsea is now Australia’s richest suburb. Its residents reported an average taxable income of $321,988 in 2023 to 2024, the highest in the country and the first time a Victorian postcode has topped the ATO list.
- The median house sits around $2.9 million, among the highest in Victoria, in a tightly held, supply-constrained market built on lifestyle and capital growth rather than rental yield.
- It is a prestige purchase, so the lending is too. Large loan sizes, valuations that swing between lenders, and the major banks tightening at the top all apply here.
- Many Portsea homes are second homes. Holiday-home and non-primary-residence lending has its own policies, and not every lender treats it the same way.
- The lender choice decides the deal. Matching a Portsea purchase to a lender comfortable with its size, its valuation and its purpose is exactly what we do.
Portsea has always been where Melbourne’s old money summers, a small, exclusive pocket at the tip of the Mornington Peninsula known for grand beach houses, the back beach and a fiercely tightly held property market. In 2026 it became something else too: the richest suburb in Australia, with its permanent residents reporting an average taxable income of $321,988, enough to knock Sydney’s eastern suburbs off the top of the ATO list for the first time.
If you are buying here, the lending is not the same conversation as an ordinary suburb. This is a prestige market, and prestige markets have their own rules. At Everstone Finance we arrange these loans regularly, and this is the plain-English guide to financing a Portsea home: the market, what changes at this price point, the holiday-home factor, and how to land with the right lender.
The Portsea market
Portsea is a small, prestige coastal market at the tip of the Mornington Peninsula, with a median house price around $2.9 million. Supply is tightly held, rental yields are low, and buyers are drawn by lifestyle and long-term capital growth rather than income return. The right home rarely comes up, and when it does it moves quickly.
What makes Portsea distinctive as a lending proposition is its scarcity. There are very few permanent residents, the housing is dominated by high-value holiday and weekender homes, and comparable sales are thin because so little trades. That scarcity supports values, but it also makes each property something of a one-off, which matters a great deal when a lender comes to value it.
Financing a Portsea home
A Portsea purchase is a high-value purchase, so everything in our guide to high-value and prestige home loans applies. Three things in particular shape a Portsea deal.
- Loan size. At these prices, income stops being the binding constraint, because salary does not scale to a multi-million-dollar home. Equity, structure and the lender’s appetite for a large exposure matter more.
- Valuation variance. Because so few comparable homes sell, Portsea valuations lean heavily on the valuer’s judgement, and two lenders can land well apart on the same property. Choosing a lender whose valuation approach suits the home can change your deposit.
- The right lender. The major banks tighten on large loans and unusual properties. Specialist and non-bank lenders are often the better fit for a Portsea purchase, and matching the right one is the job.
The holiday-home factor
Many Portsea homes are second homes rather than primary residences, and lenders treat holiday homes differently. Most will still lend strongly against a quality holiday home, but policies on rental treatment, location and acceptable security vary, so the lender needs to be one comfortable with a non-primary-residence purchase in a coastal market.
If the home is genuinely a second residence, the lender will not usually count holiday rental income the way it would a standard investment, and some are more cautious about coastal or lifestyle locations. None of this is a barrier, it simply narrows the field to lenders that understand the purpose of the purchase, which is part of what we match for you.
How your income is read
A great many Portsea buyers are business owners and company directors whose taxable income, the figure behind that record-topping ATO number, is legally minimised. Read at face value it understates them. Read properly, by a lender that adds back non-cash deductions and assesses company and trust income correctly, it reflects their real position. Our guide to self-employed home loans explains exactly how that works, and it is often the key to a Portsea approval.
For buyers upgrading or downsizing, and not wanting to sell first, bridging finance lets you secure the Portsea home before your current one sells.
