Rentvesting lets you buy an investment property while continuing to rent where you want to live.
For software developers, particularly those working in Sydney or Melbourne CBD roles, rentvesting offers a way into the property market without the need to compromise on location or wait years to save a deposit for an inner-city home. You keep the flexibility to live close to work, co-working hubs, or the lifestyle precincts you value, while building wealth through property in suburbs where rental yields and growth prospects are stronger.
How Rentvesting Works for Tech Workers
You take out an investment loan to purchase a rental property, typically in a suburb with solid fundamentals but a lower entry price than where you currently rent. The rental income offsets some of your holding costs, and you claim interest and other expenses as tax deductions. Meanwhile, you continue renting in the area that suits your work and lifestyle.
In our experience, developers with stable income and a solid deposit often qualify for competitive investor interest rates, particularly when borrowing through an ADI with access to discounted products. The key difference from an owner-occupied loan is that lenders assess your serviceability with the investment loan interest rate plus a 3.0 percentage point buffer, as required by APRA, and factor in rental income at a discounted rate to account for vacancy and management costs.
Consider a developer renting in Surry Hills who purchases a two-bedroom unit in a well-connected outer suburb. The rental income covers most of the mortgage repayment, and the borrower claims interest, property management fees, council rates, and building insurance as deductions. Over time, the property appreciates, and the developer builds equity without needing to relocate or take on a mortgage sized for Sydney's inner suburbs.
Investment Loan Borrowing Capacity and Serviceability
Lenders calculate your borrowing capacity by assessing your income, existing debts, and living expenses, then applying the 3.0 percentage point serviceability buffer to the loan product rate. For investment loans, they also include an estimate of rental income, typically discounted by around 20 per cent to account for vacancy and ongoing costs.
If you hold equity shares or receive bonuses, these can be factored into your application. We work with lenders who understand how to assess non-salary income for tech professionals, including RSUs that vest on a regular schedule. Rental income from the investment property is treated as assessable income for serviceability purposes, but the discounted figure means it does not increase your borrowing capacity dollar-for-dollar.
From 1 February 2026, APRA introduced a debt-to-income lending limit that applies to ADIs. Each lender can provide up to 20 per cent of new investor loans to borrowers with a total DTI ratio of six times or greater. This does not prevent high earners from accessing credit, but it does mean that lenders manage their high-DTI allocations carefully, and borrowers with strong deposit positions and low existing debts will have the most flexibility when structuring their investment loan application.

Variable Rate vs Fixed Rate for Investment Loans
Most rentvesting strategies benefit from a variable rate loan with offset or redraw facilities, particularly if you plan to use surplus cash flow to reduce interest costs or build a buffer for future rate movements.
A variable rate gives you the flexibility to make extra repayments without penalty, and any funds in an offset account reduce the interest charged on the loan balance. For developers who receive irregular income such as performance bonuses or equity vesting events, an offset account allows you to park those funds and reduce interest costs without locking the capital into the loan principal.
Fixed rate products provide certainty over repayments for a set period, typically one to five years, but they come with restrictions on extra repayments and may incur break costs if you refinance or sell before the fixed term ends. In a rentvesting scenario where you may want to sell the investment property and upgrade to an owner-occupied home within a few years, a variable rate product generally offers more flexibility. Some borrowers split their loan between variable and fixed portions to balance rate certainty with flexibility, but this adds complexity and may not suit all situations.
Interest-Only Repayments and Cash Flow Management
Interest-only repayments reduce your monthly loan cost by deferring principal repayments for a set period, usually up to five years. This structure is common for investment loans because it maximises your tax-deductible interest and frees up cash flow for other purposes, such as saving for an owner-occupied property deposit or reinvesting into your portfolio.
Under APRA Prudential Standard APS 112, interest-only loans attract higher risk-weighted capital requirements for lenders, which can flow through to slightly higher interest rates compared to principal and interest loans. If your LVR is above 80 per cent and the interest-only period exceeds five years or is unspecified, the loan is classified as non-standard, which further increases the lender's capital cost and may narrow your product options.
For a developer planning to transition from rentvesting to owner-occupation within a few years, an interest-only period allows you to minimise holding costs on the investment property while building savings for your next purchase. After the interest-only period ends, the loan typically reverts to principal and interest repayments, and the repayment amount increases. You can often apply to extend the interest-only term, subject to lender policy and a fresh serviceability assessment.
Tax Treatment and Deductibility Under Current Rules
Interest on borrowings used to purchase or hold a rental property is deductible against your assessable income, along with other holding costs such as property management fees, insurance, council rates, and depreciation. If the property was purchased or under contract before 7:30pm AEST on 12 May 2026, or is an eligible new build acquired after that date, losses from the property can be deducted against all income, including your salary.
For established properties acquired after 12 May 2026, losses can only be offset against other residential property income from the 2027-28 income year onward, under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026. Excess losses are carried forward and can be used to offset future residential property income, including capital gains. Properties acquired between 12 May 2026 and 30 June 2027 can be negatively geared under the current rules until 30 June 2027 only.
Eligible new builds, which include dwellings constructed on previously vacant land or builds that increase the number of dwellings on a site, retain full negative gearing treatment regardless of purchase date. A knock-down rebuild that does not increase dwelling numbers is not considered an eligible new build.
From 1 July 2027, the 50 per cent CGT discount for individuals on residential investment properties is replaced by cost base indexation using CPI and a 30 per cent minimum tax rate on real capital gains accruing from that date. For properties owned before 1 July 2027 and sold after that date, gains are apportioned between the pre-1 July 2027 period, which is taxed under current rules, and the post-1 July 2027 period, which is taxed under the new rules. Investors in eligible new builds can choose between the existing 50 per cent discount and the new indexation and minimum rate arrangements at the time of disposal.
You should speak to a tax adviser before structuring your investment, particularly if you are acquiring an established property after 12 May 2026 or planning to hold the property across the 1 July 2027 CGT transition date.
Rentvesting in Brisbane or Melbourne Growth Corridors
Developers working remotely or on hybrid schedules often choose to rentvest in Brisbane or Melbourne's outer growth corridors, where entry prices are lower and rental yields stronger than in the inner suburbs where they prefer to live.
In Brisbane, suburbs within 15 to 20 kilometres of the CBD, particularly those with planned or recent infrastructure upgrades, have attracted investor interest. Proximity to universities, hospitals, and transport nodes supports rental demand, and rental yields in these areas are typically higher than in inner-city Brisbane or Sydney. When assessing an investment property in Brisbane, consider the local vacancy rate, which affects your rental income assumptions, and the mix of tenant demand. Suburbs with a high proportion of young professionals or postgraduate students may experience more turnover but also maintain consistent rental demand.
In Melbourne, growth corridors in the city's north and west have seen significant residential development, supported by transport projects and expanding employment hubs. These areas often offer newer stock at a lower price point than established inner suburbs, and rental demand is driven by a mix of families, essential workers, and students. Body corporate fees on units in newer developments can be higher than in older buildings, particularly where the complex includes shared facilities such as gyms or pools. These fees are deductible but need to be factored into your cash flow projections.
Refinancing Your Investment Loan
Refinancing an investment loan can give you access to a lower interest rate, release equity for further investment, or allow you to restructure your loan features as your strategy evolves. Lenders regularly adjust their rate discounts and product offerings, and the rate you were offered at settlement may no longer be the most competitive available.
When refinancing, the lender will reassess your serviceability using current income, debts, living expenses, and rental income from the property. If the property has increased in value since purchase, your LVR will have improved, which may open up access to better rates or remove the need for LMI on any additional borrowing. If you are planning to purchase an owner-occupied property in the near term, refinancing the investment loan to release equity can provide part of your deposit, though this will increase your total debt and reduce your borrowing capacity for the new purchase.
For developers who have rentvested for a few years and are now looking to transition into owner-occupation, refinancing the investment loan to a competitive rate and loan structure can reduce your ongoing holding costs and improve your serviceability for the new owner-occupied loan. We regularly assist clients with investment loan refinancing to align their lending with their current strategy and income position.
Structuring Your Rentvesting Loan for Future Flexibility
When setting up your investment loan, consider how your situation may change over the next few years. If you plan to purchase an owner-occupied property, you will need to demonstrate serviceability for both loans simultaneously, and the investment loan interest will remain deductible only if the borrowings continue to be used for investment purposes.
Using an offset account rather than making extra repayments directly into the loan principal preserves your ability to redraw funds for other purposes without affecting the deductibility of interest. If you pay down the loan principal and later redraw funds for private purposes, the interest on the redrawn portion is not deductible. Keeping surplus funds in an offset account achieves the same interest saving while maintaining full flexibility over how you use the capital.
If you are purchasing the investment property with a deposit below 80 per cent LVR, you will need to pay LMI. The premium is typically capitalised into the loan amount, and the interest on that capitalised premium is deductible. Some lenders offer LMI waivers for high-income professionals, though these are more commonly available for owner-occupied loans than investment loans. Where a waiver is not available, paying LMI allows you to enter the market sooner rather than waiting to save a larger deposit, and the cost is spread over the life of the loan.

Frequently Asked Questions
What is rentvesting and how does it work for software developers?
Rentvesting means buying an investment property while continuing to rent where you want to live. For software developers, it allows you to enter the property market in an affordable suburb while renting in a location that suits your work and lifestyle, with rental income and tax deductions offsetting holding costs.
Can I claim tax deductions on an investment property purchased after May 2026?
Yes, but the rules depend on when you purchased and whether the property is an eligible new build. Established properties acquired after 12 May 2026 can only offset losses against other residential property income from the 2027-28 income year onward. Eligible new builds retain full negative gearing treatment regardless of purchase date.
Should I choose a variable or fixed rate for my rentvesting loan?
Most rentvesting strategies benefit from a variable rate with an offset account, as it allows extra repayments, flexibility to access funds, and lower interest costs. Fixed rates provide repayment certainty but limit extra repayments and may incur break costs if you sell or refinance early.
How does APRA's serviceability buffer affect my investment loan borrowing capacity?
APRA requires lenders to assess your ability to service the loan at an interest rate 3.0 percentage points above the product rate. This reduces your maximum borrowing capacity compared to an assessment at the actual rate, and rental income is typically discounted by around 20 per cent in the serviceability calculation.
What are the benefits of using an offset account for an investment loan?
An offset account reduces the interest charged on your loan balance without requiring you to pay down the principal. This preserves your ability to access the funds for other purposes while maintaining the full tax deductibility of interest on the loan.
