Everything You Need to Know About Investment Loans and Property Investment Goals

A property investment loan shapes what you can build, how fast you can grow, and which opportunities you can reach for when they appear.

The loan you choose today either supports or limits the portfolio you're trying to create. That includes how much you can borrow, whether you can release equity from your owner-occupied home, what rental income lenders will recognise, and how the repayment structure affects your cashflow and tax position. Before you commit to a product, you need to know what you're building towards.

What Makes an Investment Loan Different From a Home Loan

An investment loan is secured against property you intend to rent out rather than live in. Lenders treat these loans differently because they carry different risks, which flows through to interest rates, deposit requirements, and serviceability tests. Variable rates on investor loans typically sit 0.20 to 0.50 percentage points higher than owner-occupier rates, and lenders apply stricter income assessments because rental income is not guaranteed.

Borrowers also need to factor in that lenders discount rental income by around 20 per cent when calculating serviceability to account for vacancy periods and maintenance costs. If you're planning to use equity from your Launceston home to fund a deposit on a rental property elsewhere, the existing mortgage on that home will also count towards your total debt, which affects how much you can borrow. Understanding these differences early allows you to structure your application around what lenders will actually assess, rather than what you hope they might accept.

Choosing Between Interest Only and Principal and Interest

Interest only loans allow you to pay only the interest portion of the loan for a set period, typically one to five years, which reduces your monthly repayments and may improve cashflow. Principal and interest loans require you to pay down the loan balance from the start, building equity as you go.

For many Launceston investors, interest only repayments make sense during the early years when rental yield may not cover all holding costs and negative gearing creates a tax benefit. The lower repayment leaves more flexibility to service other debts or save towards the next deposit. Consider a buyer who uses equity from a home in Riverside to purchase a unit in the Launceston CBD. The unit rents for $400 per week, which lenders discount to $320 per week for serviceability purposes. An interest only loan on a $400,000 borrowing at current variable rates might cost around $1,400 per month in interest, compared to $2,200 per month on principal and interest. The difference supports cashflow during the holding period, and interest costs remain fully deductible against rental income. Once the interest only period ends, the loan typically reverts to principal and interest unless you apply to extend it, which may require a new valuation and serviceability check.

Using Equity to Fund Your Deposit

Equity is the portion of your property that you own outright, calculated as the current market value minus what you owe on the mortgage. If your Launceston home is worth $600,000 and you owe $350,000, you have $250,000 in equity. Lenders generally allow you to borrow up to 80 per cent of the property's value without incurring Lenders Mortgage Insurance, which means you could access around $130,000 from that equity position to fund a deposit and purchase costs on an investment property.

Releasing equity involves refinancing your existing home loan or taking out a separate line of credit secured against your home. The borrowed funds can then be used for the deposit, stamp duty, and other upfront costs on the investment property. Because the borrowed funds are used to acquire an income-producing asset, the interest on that portion of the loan is typically deductible. Many investors in Launceston use this approach because it avoids the need to save a second deposit in cash, allowing them to act on opportunities sooner. You can read more about how this process works on our refinancing page.

How Lenders Assess Your Borrowing Capacity for Investment Loans

Lenders calculate how much you can borrow by assessing your income, existing debts, living expenses, and the rental income the investment property will generate. APRA requires all banks and authorised lenders to assess new borrowers' capacity to service a home loan, including a residential investment loan, at an interest rate that is at least 3.0 percentage points above the loan product rate. This buffer has been in place since October 2021 and applies to all new lending.

APRA also activated a debt-to-income lending limit on 27 November 2025, effective from 1 February 2026. Each lender may lend up to 20 per cent of new investor loans to borrowers with a total debt-to-income ratio of six times or greater. If your total household income is $120,000 and your proposed borrowing across all loans, including the new investment loan, would be $750,000, your DTI ratio is 6.25. Most applicants will still be assessed within the limit, but borrowers with high debt relative to income may face additional scrutiny or need to reduce their loan amount. Working with a broker who understands these thresholds and can structure your application accordingly makes a tangible difference to what you can access. Our borrowing capacity page has more detail on how these calculations work in practice.

Variable Rate or Fixed Rate for Property Investment

Variable rate loans move with the market, which means your repayments can rise or fall depending on rate changes. Fixed rate loans lock in your interest rate for a set period, typically one to five years, which provides certainty over repayments but limits flexibility if you want to make extra repayments or sell early.

Many investors in Launceston choose variable rates because the loan structure allows unlimited extra repayments, full redraw or offset account access, and no break costs if the property is sold. The downside is that repayments can increase if rates rise, which affects cashflow and serviceability for future borrowing. Fixed rates suit investors who value predictable repayments and plan to hold the property without making large additional payments during the fixed period. Some investors split their loan between fixed and variable to balance certainty with flexibility. If you currently hold a fixed rate loan and are reviewing your options as the fixed period ends, our fixed rate expiry page outlines what to expect.

Tax Benefits and Claimable Expenses on Investment Property

Interest on borrowings used to acquire or hold residential rental property is deductible against assessable income to the extent the property is rented or held to produce assessable income. Other ongoing holding costs, such as council rates, insurance, property management fees, repairs and depreciation, are deductible under existing ATO rules for the period the property is rented or genuinely available for rent.

Losses from residential investment properties held at 7:30pm AEST on 12 May 2026, including properties under contract awaiting settlement at that time, continue to be fully deductible against other income, including salary and wages, until the property is sold. Losses from new builds acquired after 12 May 2026 can also continue to be deducted against all income. For established properties purchased after that date, losses related to established residential investment properties acquired after 7:30pm AEST on 12 May 2026 are deductible only against other income from residential properties, including capital gains on residential properties, from the 2027-28 income year. The change affects how negative gearing works for new investors buying established stock, and it shifts the relative appeal of new builds for those planning to negatively gear during the early holding period.

Portfolio Growth and Leveraging Multiple Properties

Building a portfolio of investment properties relies on your ability to borrow against equity in properties you already own while maintaining serviceability across all loans. Each time a property increases in value, you create additional equity that can be used to fund the next purchase. Growth in Launceston's residential market over recent years has allowed many local investors to leverage their original home into a second or third property without needing to inject large amounts of additional cash.

The challenge is that each new loan reduces your remaining borrowing capacity, and lenders assess the combined serviceability of all your debts, not just the new one. Rental income from existing properties helps offset this, but it is still discounted by around 20 per cent. Investors building portfolios in Launceston and surrounding areas often work with a mortgage broker who can structure loans across multiple lenders, maximise rental income recognition, and ensure each new purchase leaves enough capacity for future growth. If you're holding multiple loans and want to consolidate or restructure, a loan health check can identify whether your current setup still supports your goals.

Accessing Investment Loan Options Across Multiple Lenders

Different lenders offer different investor loan products, with variations in rates, LVR limits, interest only periods, offset account availability, and how they assess rental income. Some lenders are more accommodating of high LVR lending or complex income structures, while others offer better rates for borrowers with strong equity positions and straightforward applications.

Blue Gum Loans works with banks and lenders across Australia, which means we can match your investment goals and financial position to the lender most likely to support what you're trying to build. For a Launceston investor looking to purchase a second property using equity, that might mean a lender who offers competitive variable rates and full offset access. For a buyer purchasing a new build to maximise tax benefits, it might mean a lender with strong interest only terms and flexible serviceability assessment. The right product depends on your specific situation, and having access to multiple options allows you to choose the one that fits rather than adapting your strategy to suit a single lender's policy. You can explore the range of investment loans we arrange through our main investment loans page.
