# I Gave Up Buying My Own Home at 27. Best Financial Decision I Ever Made.

*By Yan Zhu, Co-Founder & Chief Data Officer at PremiumRea — 2025-09-22*

> Every financial planner I met said the same thing: get on the property ladder with your own home. The maths told a completely different story.

I was 25 when a colleague at the actuarial firm told me I was "throwing money away" by renting a one-bed in South Yarra. He'd just signed for a two-bedroom townhouse in Chadstone — $890,000, thirty-year mortgage, every cent of his deposit gone.

Two years later he turned down a job offer in Singapore because he couldn't stomach the idea of selling at a loss or renting out a property that was bleeding $800 a month in negative cash flow. The opportunity cost of that decision? Conservatively, $400,000 in total compensation over three years.

His townhouse went up maybe $60,000 in that time.

I'm not saying homeownership is bad. I'm saying the order matters — and for most Australians under 35, buying an investment property first and renting where you actually want to live is the mathematically superior play. The industry calls it rentvesting, and after running the numbers across hundreds of client scenarios, I'm more convinced than ever that it's the single best wealth-building strategy available to young Australians right now.

## What rentvesting actually means (and what it doesn't)

Rentvesting is dead simple: you rent your home in the suburb you want to live in, and you buy an investment property in a suburb where the numbers work. You separate lifestyle from wealth creation.

This isn't about deprivation. You're not eating two-minute noodles in a share house. You could be paying $650 a week to rent a beautiful terrace in Fitzroy while your investment property in Cranbourne — bought for $680,000 on a 600-square-metre block — returns $520 per week in rent and grows at 8% per annum [1].

The distinction from "just renting" is that you own an appreciating asset. You're building equity. You're getting the tax benefits (negative gearing, depreciation, interest deductions). You're just not sleeping in it.

"The biggest mental shift for young clients is accepting that the house you live in and the house you invest in serve completely different purposes," says Yan Zhu, Co-Founder & Chief Data Officer at PremiumRea. "Trying to optimise for both simultaneously almost always means you end up with a mediocre version of each."

## The maths nobody wants to hear

Let me lay this out with real numbers, because that's where the conversation gets uncomfortable for the "buy your own home first" crowd.

**Scenario A — Buy your own home:**
You have $200,000 in savings. You buy a two-bedroom unit in Glen Waverley for $950,000 (the bottom of the market there in mid-2024). Stamp duty: ~$52,000. You're left financing $800,000 at 6.3% interest-only. Annual holding cost: roughly $50,400 in interest alone. Add council rates ($2,800), water ($700), insurance ($1,800), maintenance ($2,000). Total annual cost: $57,700. That's $1,110 per week out of your pocket — with zero rental income and zero tax deductions because it's your principal place of residence.

Glen Waverley units have grown at around 2.8% per annum over the past decade [2]. After ten years your $950K unit might be worth $1.27 million. Capital gain: $320,000.

**Scenario B — Rentvest:**
Same $200,000. You buy a 630-square-metre house in Hampton Park for $700,000. Stamp duty: ~$38,500. You finance $560,000 at 6.5% IO. The property rents at $550/week after a light renovation ($15,000). You also rent a nice apartment in Glen Waverley for $500/week — better than the unit you would have bought, honestly.

Annual cost of investment property: interest $36,400, council $2,200, water $650, insurance $1,500, land tax $1,950, management 4.9% of rent ($1,401). Total: $44,101. Rental income: $28,600. Net cost: $15,501 — but roughly $7,000 of that comes back via negative gearing deductions at the 37% marginal rate. Real annual cost of the investment property: ~$8,500. Add your own rent: $26,000 per year. Total housing cost: $34,500 per year. That's $663 per week.

Hampton Park houses have grown at 7.4% per annum over the past decade [3]. After ten years your $700K house is worth approximately $1.42 million. Capital gain: $720,000.

Scenario A: you spend $57,700/year and gain $320K.
Scenario B: you spend $34,500/year and gain $720K.

The rentvestor spends $23,200 less per year AND ends up $400,000 richer. Over ten years, the total advantage is roughly $632,000.

## "But renting is throwing money away"

No it isn't. I hear this from well-meaning parents at least twice a week. Let me be blunt about it.

When you pay $500 a week in rent, you're paying for shelter. When you pay $1,110 a week on a mortgage (interest, rates, insurance, maintenance), you're also paying for shelter — plus you're paying $50,400 a year in interest to a bank. That interest is money you will never see again. It's functionally identical to rent, except it's more expensive and it's not tax-deductible because it's your own home.

The only portion of a mortgage that builds equity is the principal repayment. On an interest-only loan, you're building zero equity from repayments — all your equity growth comes from the property appreciating. And as I showed above, a $700K house in a growth corridor appreciates far more than a $950K unit in an established area.

Victoria's rental laws are among the strongest tenant protections in the country [4]. Landlords cannot evict without reason. Rent increases are limited to once per year. Minimum standards cover heating, locks, window coverings, electrical safety. Renters in Victoria have more legal security than renters in most comparable cities globally.

The "security" argument for homeownership is emotional, not financial. And I say that as someone who genuinely respects the emotional value of owning your own space. But financial decisions should be made financially.

## The hidden cost nobody calculates: your life choices

This is the part that hit me personally.

A close friend — also an actuary, brilliant bloke — bought a townhouse near the CBD two years after graduation. Not long after, a startup in Sydney offered him equity plus a senior role. The catch: the company might fold in six months. Startups are like that.

He ran the numbers. If it failed, he'd be unemployed in a city where he didn't own property, with a Melbourne mortgage still ticking. In a soft job market, finding something equivalent could take months. The risk of missing mortgage repayments was too real.

So he stayed.

That startup completed its Series C last year. The equity he would have held is now worth enough to buy five of his townhouses. Cash.

I'm not saying everyone should gamble on startups. I'm saying that a $900,000 mortgage at age 27 compresses your life into a single narrow corridor. You can't take the overseas posting. You can't start the business. You can't even take a lower-paying job that you'd actually enjoy, because the mortgage doesn't care about your career satisfaction. It just wants its $4,200 a month.

Rentvesting keeps your options open. Your investment property is managed by professionals. Your rent is a known, controllable expense. You are free to make bold moves with your career because your housing situation is flexible.

## How to actually do it: a step-by-step for first-timers

Right, enough philosophy. Here's how this works in practice.

**Step 1 — Get your borrowing capacity assessed.** Before looking at a single property, talk to a mortgage broker (or banker, if you can get a senior one). A rough rule: your borrowing power is about 5x your gross annual salary. On $130,000 income with $170,000 in savings, you're looking at a purchase budget around $750,000 [5].

**Step 2 — Use your first home buyer benefits on an investment property.** In Victoria, first home buyers get full stamp duty exemption on properties under $600,000 and a sliding scale up to $750,000 [6]. You can buy a $700K property and save roughly $15,000 in duty. Yes, you need to live in it for 12 months first. Do that. Then move out and rent it.

Step 3 — buy land, not building. This is the principle our team repeats constantly. Your investment property should have land value making up at least 80% of the total price. A $700K house on 600sqm in Cranbourne or Hampton Park has roughly $580K in land value and $120K in depreciated building [7]. The land appreciates. The building doesn't. You want maximum exposure to the thing that goes up.

**Step 4 — light renovation, then rent.** After your 12-month owner-occupier period, spend $10,000-$15,000 on a cosmetic refresh (paint, new SPC flooring, modern light fittings). This bumps rental returns by $50-$80 per week without touching the structure. Our internal data shows that a $13,000 renovation in the southeast corridor typically lifts weekly rent by $400 when combined with a layout optimisation [8].

**Step 5 — rent somewhere you love.** This is the whole point. You've got a growth asset doing the heavy lifting. Now go live in the suburb that makes you happy. Pay $500-$650/week for something you couldn't afford to buy, and enjoy zero maintenance responsibilities.

## The six-year CGT rule — your secret weapon

Here's a tax angle most people miss entirely. If you live in the property as your main residence and then move out and rent it, you can treat it as your principal place of residence for up to six years under the ATO's "absence rule" [9]. During that six-year window, any capital gains on the property are completely tax-free.

So you buy at $700K. Live in it for 12 months. Move out. Rent it for five years. Sell at $1.1 million. Capital gain: $400,000. CGT payable: zero. Not fifty percent. Zero.

If you hold beyond six years, you lose the full exemption but can still apportion the gain based on the period it was your main residence versus the investment period. The point is: the six-year rule gives rentvestors a massive tax advantage that pure investors don't get.

This is why I tell every young client the same thing: your first property purchase should be something you can live in for 12 months — not necessarily something you want to live in forever. Think of it as a temporary arrangement with a $400,000 payoff.

"Most of our clients under 30 use this exact playbook," says Yan Zhu. "Buy in a growth corridor, live in it for a year, convert to investment, rent where you want. The tax saving alone on a $400K gain is over $70,000 at the 37% marginal rate."

## What about the 'real security' argument?

I want to address this honestly, because it's not entirely wrong.

Owning your home does provide a kind of psychological stability that renting can't fully replicate. You can renovate how you want. Nobody can sell the property out from under you. There's a deep, almost primal satisfaction in owning the walls around you.

But here's the thing — real financial security comes from what you can handle, not what you own. A person with $1.4 million in property equity and $35,000 in annual housing costs has infinitely more security than someone with a $900K mortgage eating $57,000 a year and zero liquidity.

Security isn't a title deed. Security is options. Security is the ability to weather a job loss, a health crisis, or a market downturn without losing sleep. And the rentvestor — with lower annual costs, higher net worth, and more liquid reserves — is objectively in the stronger position.

After working with over 350 property transactions, I've watched dozens of young buyers stretch themselves to breaking point for an owner-occupied property they'll outgrow in five years anyway. Meanwhile, the ones who bought a solid investment first are already onto their second or third asset.

## When rentvesting stops making sense

I should be honest about the limitations too.

If you're 45 with kids in school and a stable career anchored to one city, buying your own home is probably the right call. The lifestyle benefits compound over time, and at that stage you've presumably already built some investment assets.

If property prices in your target area are flat or declining while rents are climbing fast, the rent-vs-buy equation can flip. This happened briefly in parts of inner Melbourne during 2022-2023 when interest rates spiked and rents surged simultaneously [10].

And if you simply cannot stomach the idea of not owning where you sleep — if it keeps you up at night — then buy your home. Financial optimisation means nothing if it makes you miserable. But at least run the numbers first. Know what you're giving up.

For most Australians under 35 with less than $250,000 in savings, rentvesting remains the mathematically dominant strategy. Not by a little. By a lot.

## The first property you buy should be an investment

I'll leave you with this.

Every dollar you lock into an owner-occupied property is a dollar that isn't working for you. It's not generating tax deductions. It's not producing rental income. It's not positioned in the highest-growth corridor. It's just sitting there, attached to your emotional preferences.

The clients who build wealth fastest are the ones who separate where they live from where they invest. Full stop. They buy a $700K house on 600sqm in a growth suburb, rent it at $500-$550 a week, and live wherever suits their lifestyle. After three to five years, they refinance, pull out $80,000-$100,000 in equity, and buy property number two. Then number three.

That's not theoretical. That's the actual path we've walked with over a hundred clients since 2022.

Your first home should be a financial asset, not a lifestyle purchase. Buy the investment first. Your dream home comes later — and when it does, you'll be buying it with the profits from assets that have been compounding for years.

I'm Yan, an actuary turned property strategist. And I reckon the smartest thing a young Australian can do today is stop thinking about "getting on the ladder" and start thinking about building a portfolio.
