# I Scored Melbourne's Most-Asked Suburbs Out of 10. Most Failed.

*By Yan Zhu, Co-Founder & Chief Data Officer at PremiumRea — 2025-12-11*

> Everyone asks me to rate their favourite suburb. So I built a framework — five metrics, each scored out of 2, total out of 10. Cranbourne got an 8. Point Cook got a 4. Williamstown got a 3. The popular choice and the profitable choice are rarely the same thing.

The most common DM I receive: "Yan, what do you think of [suburb]?"

I used to answer these one at a time, doing 20 minutes of research per request. Then I realised I was applying the same five criteria every time. So I built a scoring framework — transparent, repeatable, data-driven — and started publishing the results.

Today I'm sharing scores for six of the most frequently asked suburbs. Some will confirm what you already suspected. Others might make you uncomfortable, especially if you already own there.

The framework scores each suburb on five dimensions, each worth up to 2 points, for a total out of 10:

1. **Affordability ratio** (price-to-income): How affordable is the suburb relative to local household income? Lower ratios score higher.
2. **Population growth trajectory**: Is the suburb gaining or losing population? Net inflow scores higher.
3. **Rental vacancy rate**: Sub-2% scores 2/2. Above 3% scores 0/2.
4. **Supply pipeline**: Is new housing development flooding the suburb? More new supply = lower score.
5. **Development upside**: Can existing properties be improved, subdivided, or converted? More optionality = higher score.

Let's go through the results.

## Cranbourne: 8 out of 10

Cranbourne is the suburb I've directed the most client investment toward over the past two years, and the scoring backs up that conviction.

**Affordability (2/2):** Median house price around $680,000 against a local household income that puts the price-to-income ratio at roughly 7x. Comfortably affordable for dual-income families.

**Population growth (2/2):** Strong positive net migration. Young families and interstate returnees settling in the Casey corridor. One of Melbourne's fastest-growing LGAs.

**Vacancy (1.5/2):** Currently sitting around 1.5-2%. Tight, though not quite as compressed as Hampton Park.

**Supply (1.5/2):** Some new development on the fringes (Clyde, Cranbourne East), but the established areas have limited new stock. The mixed-use commercial land zoning in parts of Cranbourne provides long-term value uplift without immediate oversupply.

**Development upside (1/2):** Block sizes are reasonable (500-600sqm in established areas) with granny flat potential. Some subdivision opportunities, though not as generous as older eastern suburbs with 700+sqm blocks.

Cranbourne benefits from being one of only two suburbs in Melbourne's far southeast with commercial-zoned land suitable for mixed-use development. That's a long-term value driver that most investors overlook [1].

The demographic profile is also stronger than the stereotype suggests. Over 50% owner-occupier, Anglo-Australian majority with a diverse multicultural mix. The "Cranbourne is rough" narrative is outdated and not supported by current crime or demographic data.

## Rowville: 6 out of 10

Rowville is a genuinely nice suburb. Good schools, quiet streets, established trees. But "nice" and "investable" are different things.

**Affordability (1/2):** Median approaching $1.16 million. With local household weekly income of $2,740, the price-to-income ratio is roughly 8x — at the outer edge of comfortable.

**Population growth (1/2):** Moderate. Rowville is established and largely built out. Population growth over the next 25 years is projected at only 3,200 additional residents — modest compared to growth corridors.

**Vacancy (1.5/2):** Reasonable at around 2%. Not problematic but not exceptionally tight either.

**Supply (1/2):** This is where it gets concerning. Over 1,500 new dwellings are projected in the planning pipeline. For a suburb adding only 3,200 people, that's fewer than 2 residents per new dwelling. Supply is outpacing demand.

**Development upside (1/2):** Limited. Block sizes in Rowville are generally 500-600sqm but the established, higher-value character of the suburb makes council approvals for granny flats and multi-dwelling development more contentious.

Rowville scores a solid 6 — not a disaster by any means, but not a standout investment suburb either. If you already own here, hold. If you're considering buying for investment, the same capital buys significantly more growth potential in Cranbourne or Hampton Park [2].

## Point Cook: 4 out of 10

Point Cook is popular with first-home buyers and families. It's also a classic example of a suburb where popularity doesn't equal investment performance.

**Affordability (1/2):** Median around $750,000. Affordable-ish, but higher than comparable western suburbs.

**Population growth (1/2):** Slowing. The initial rapid growth phase is well past, and the suburb is approaching capacity.

**Vacancy (0.5/2):** Concerning. Vacancy rates have been creeping above 3%, driven by oversupply of similar-quality housing stock and proximity to new development areas.

**Supply (0/2):** This is the killer. Point Cook was one of Melbourne's most aggressive greenfield development areas. New stock keeps coming onto the market, competing directly with existing properties. When supply is abundant, capital growth stalls.

**Development upside (0.5/2):** Most blocks are 400-500sqm with minimal ability to add meaningful rental income through conversion or granny flats. The cookie-cutter housing stock provides no differentiation.

If you're buying in Point Cook for lifestyle reasons and can afford to hold without relying on capital growth, that's a personal choice. But as an investment, the numbers don't work relative to available alternatives [2].

## Williamstown: 3 out of 10

This one will upset some people. Williamstown is gorgeous. Bayside charm, heritage character, strong community. As a lifestyle choice, it's excellent. As an investment? The numbers are brutal.

**Affordability (0/2):** Median house price well above $1.5 million. Price-to-income ratio exceeds 12x. Deeply unaffordable.

**Population growth (0.5/2):** Minimal. Heritage overlays and coastal zoning restrict new development.

**Vacancy (1/2):** Moderate — around 2-2.5%. Acceptable but not exceptional.

**Supply (1/2):** Low new supply thanks to heritage restrictions — but this cuts both ways. Restricted supply also means restricted development upside.

**Development upside (0.5/2):** Severely limited by heritage overlays and council resistance to densification. Many properties cannot be meaningfully altered.

A suburb that scores 3 out of 10 on an investment framework can still be a wonderful place to live. But wonderful and wealth-building are different objectives, and conflating them is how people end up asset-rich and cash-poor [2].

If you're looking at luxury renovation projects, Williamstown could work — buy a heritage-listed property, do a sympathetic restoration, and sell to a lifestyle buyer at a premium. But that's a development play, not an investment play, and it requires deep pockets and specialist expertise.

## The scorecard isn't the whole story — but it's the starting point

A few caveats before people take these scores as absolute truth.

First, the scores represent suburb-level averages. Within any suburb, individual properties can outperform or underperform based on specific attributes — block size, street position, renovation potential, zoning classification. A high-scoring suburb can still contain bad properties, and a low-scoring suburb can contain gems.

Second, these scores are calibrated for cash-flow investors seeking a combination of capital growth and rental yield. If your investment objectives are different — for example, if you're exclusively focused on luxury development or land banking — the weighting of each dimension would change.

Third, scores change over time. A suburb that scores 4 today might score 6 in three years if affordability improves or supply dynamics shift. The framework should be reapplied regularly, not treated as a permanent verdict.

> "The purpose of the scoring system isn't to give you an answer," says Yan Zhu. "It's to give you a structured way to ask the right questions. Anyone can have an opinion about a suburb. The scoring forces you to quantify that opinion — and once you quantify it, the emotional bias drops away."

If there's a suburb you want me to score, let me know in the comments. I'll keep adding to the database. And if your favourite suburb scored lower than you expected — don't shoot the messenger. The data is the data.
