The rentvesting play. When it works and when it does not.
Rentvesting means renting where you want to live and buying where the yield is. It works in cities with a wide rental-to-purchase ratio. It does not work where the ratio compresses. Here are the four cities where the maths is currently flipping.
Rentvesting is the strategy of renting where you want to live (typically inner-city, expensive, lifestyle-rich) while owning investment property elsewhere (typically suburban, yield-positive, accessible price point).
The strategy made sense in Australia between roughly 2015 and 2022 when the gap between rental cost and ownership cost in major capital cities was wide. Renting in Bondi while owning in Western Sydney generated positive arbitrage. The strategy still applies in some cities but is closing in others.
This post explains the rentvesting maths, the four cities where the calculus has changed, and the situations where it still works.
The rentvesting maths
The core comparison:
Path A: buy where you want to live
- Purchase a $1.4M Sydney inner-east apartment
- Deposit: $280,000 (20%)
- Loan: $1.12M at 6.5% = $84k annual interest
- Other ownership costs: $14k per year (rates, strata, insurance, maintenance)
- Total annual cost: $98,000
- Build equity through repayments, capital growth
Path B: rentvest
- Rent the same inner-east apartment for $1,200 per week = $62,400 per year
- Use $280,000 deposit toward a $700,000 investment property in middle-ring Sydney
- Loan: $560,000 at 6.5% = $36,400 annual interest
- Other ownership costs (investment): $12k per year
- Less rental income from investment: $32,000 per year
- Net investment cost: $16,400
- Total annual cost (rent + investment): $78,800
Path A is $19,200 more expensive per year than Path B.
Over a 10-year horizon, the rentvester is approximately $192,000 ahead in cashflow terms (ignoring capital growth differences).
Why it works (when it works)
Three factors:
Factor 1: rental yield gap
Some cities have wide gaps between gross rental yield and the cost of ownership. When yield is 3% and ownership cost is 6%, the renter pays roughly half what the owner pays for the same property.
In rentvesting, you exploit this gap on the "rent where you want" side (low yield, low rent for the lifestyle area) and the opposite on the "buy where yield is" side (higher yield, lower price).
Factor 2: capital growth differential
If the suburb you rent in grows at 6% per year and the suburb you invest in grows at 5%, the gap is 1%. Modest. The capital growth still happens; it just accrues on the investment property rather than your PPOR.
Factor 3: tax treatment
The PPOR is CGT-exempt on sale but the holding costs (interest, rates) are not tax-deductible.
The investment property is CGT-taxable on sale but the holding costs are deductible. For a high-marginal-rate investor, the tax deductibility recovers a substantial portion of the holding cost.
The four cities where the maths has changed
The rentvesting calculus depends on the gap between rental cost and ownership cost. Where that gap narrows, the strategy weakens.
In 2026, the gap has narrowed materially in:
Sydney inner-east
Rentals in suburbs like Bondi, Bondi Junction, Surry Hills have risen 18-25% over 2023-2025. The "rent where you want" side has become more expensive. Investment yields in middle-ring Sydney have also moved up (5.5-6% gross), but the gap between paying $90k+ rent on the east side and paying ownership costs is narrower than it was in 2020.
Melbourne inner-east
Similar pattern. Rents in Hawthorn, Camberwell, Glen Iris have risen sharply since 2023. The rentvester is paying more to rent than the strategy assumed.
Brisbane inner ring
Brisbane has been the strongest market in Australia 2022-2025. Rental yields have remained high but rents have risen alongside. The arbitrage between rent and ownership is smaller than it was three years ago.
Perth
Perth went through a substantial rental crunch in 2023-2024. Vacancy rates dropped to 0.5%. Rents lifted 25-35% in some suburbs. The rentvester's rent costs have outpaced what the strategy assumed.
Where rentvesting still works in 2026
Three remaining sweet spots:
Sweet spot 1: high-end Sydney harbourside
Rents in Mosman, Vaucluse, Double Bay remain a small fraction of ownership cost. Buying these properties is prohibitively expensive ($3-12M+). Renting them is "affordable" relative to ownership. The arbitrage is real for households at or above $400k income who could not realistically buy these properties anyway.
Sweet spot 2: regional capital cities
Renting in central Darwin, central Hobart, or central Adelaide remains substantially cheaper than ownership. Buying investment property in the surrounding suburbs offers yields of 6-8%. The rentvest maths still works.
Sweet spot 3: high-income professionals in early career
If your income is high ($200k+) but your savings are still building, the deposit on a $1.5M PPOR may be 5-7 years away. The deposit on a $600k investment property is 2-3 years away. Rentvesting lets you start building equity earlier.
Where rentvesting does not work
Three patterns:
Pattern 1: tight rental markets
When rents in your preferred suburb are rising 6%+ per year and the gap to ownership cost is below $20k per year, the arbitrage is too narrow to justify the strategy. Buy where you want to live.
Pattern 2: long-term family households
Renting carries instability (rental moves, tenancy disputes, landlord decisions). For families with school-age children who value housing stability, the non-financial cost of rentvesting can outweigh the financial benefit.
Pattern 3: when interest rates are high
Higher interest rates compress the investment cashflow (more of the rent goes to interest). The rentvest math depends on the investment property covering most of its own costs. At 7%+ interest rates on the investment loan, that becomes harder.
The first home buyer trap
Some first home buyers use rentvesting to enter the market because they cannot afford a PPOR in their preferred suburb. The strategy can work but introduces three complications:
- No PPOR exemption: the investment property is CGT-taxable when sold. The first home buyer's "PPOR sale" tax shelter is sacrificed.
- No FHOG: first home owner grants typically require the buyer to live in the property for 6-12 months. Rentvesting (where the property is immediately rented to tenants) usually disqualifies.
- No FHBG: First Home Buyer Guarantee requires owner-occupier intent. Rentvesting is not eligible.
The first home buyer schemes can be worth $30,000-80,000 in concessions. The rentvester forgoes them. For first home buyers whose income trajectory will lift, this trade-off needs careful consideration.
The 10-year decision
Rentvesting works when:
- The gap between rent and ownership is at least $15,000 per year
- You expect to live in your rented area for at least 5 more years
- You can find an investment property with at least 5% gross yield
- Your income trajectory supports both the rent and the investment costs
- You can tolerate the instability of rental housing
If all five hold, rentvesting builds wealth faster than buying in your preferred suburb. If two or more fail, owning where you live is the better answer.
Rentvesting is a strategy that depends on specific market conditions and personal circumstances. When the conditions align, it builds wealth efficiently. When they do not, it carries unnecessary complexity and tax cost. Knowing which scenario you are in is the difference between an informed strategy and a regretted one.
