The Easiest Way to Structure an Investment Loan

Purchasing an investment property starts with knowing what your borrowing will support and how the loan is structured.

Most investors in Rosebud look at property close to where they live or in areas they know well along the peninsula, including nearby suburbs with consistent rental demand such as Rye, Dromana and McCrae. The structure of your investment loan will determine how much you can borrow, what your repayments look like, and how much flexibility you have as the property market and your own circumstances change over time.

How Much Can You Borrow for an Investment Property?

Lenders typically lend up to 80 per cent of the property value without requiring Lenders Mortgage Insurance. Going beyond 80 per cent is possible, but the premium adds to your upfront costs and does not cover you as the borrower.

The amount you can borrow depends on your household income, existing debts, and the rental income the property will generate. Lenders assess your income against all commitments and will factor in the interest rate plus a serviceability buffer when calculating what you can afford to repay. Rental income is included, but most lenders discount it by around 20 per cent to account for periods when the property may be vacant or require maintenance.

Consider an investor earning $95,000 a year with no other debts, purchasing a two-bedroom unit near Rosebud foreshore. The property is expected to rent for $500 per week. The lender will assess rental income at $400 per week and apply the serviceability buffer to the loan rate when calculating the maximum borrowing amount. At current variable rates, the investor may be able to borrow in the vicinity of $550,000 to $620,000, depending on the lender's policy and the investor's other expenses. The actual amount varies, and working with a mortgage broker in Rosebud can help you understand where you sit before you start looking at properties.

Should You Choose Variable or Fixed Rate?

A variable rate loan moves with the market, and your repayments can rise or fall depending on what lenders do with their rates. A fixed rate locks in your repayment for a set period, usually between one and five years.

For investors, the decision often comes down to cash flow certainty versus flexibility. A fixed rate offers predictable repayments, which can help with budgeting, especially if rental income is tight. A variable rate gives you access to features such as offset accounts and the ability to make additional repayments without penalty, which can reduce the interest you pay over time.

Some investors split their loan between fixed and variable. This approach gives you a portion of stable repayments while keeping some flexibility. In our experience, investors who want to pay down debt sooner tend to favour variable or split structures, while those focused on holding long-term with minimal active management lean toward fixed.

Interest Only or Principal and Interest?

An interest-only loan means you pay only the interest portion each month and do not reduce the loan balance during the interest-only period. Principal and interest repayments cover both, so the loan balance decreases over time.

Investor loans are commonly set up with an interest-only period, typically for one to five years. Lower monthly repayments mean more cash in hand each month, which can be helpful if you are managing multiple properties or want to direct funds elsewhere. The downside is that the loan balance does not fall, and when the interest-only period ends, repayments increase as you begin paying down the principal.

If you are holding the property for long-term capital growth and want to maximise cash flow in the short term, interest-only can work well. If your goal is to build equity and eventually own the property outright, principal and interest from the start will get you there sooner. Many Rosebud investors using rental income to support a second purchase choose interest-only initially to keep repayments manageable, then switch to principal and interest once their portfolio is stable.

What Loan Features Actually Matter for Investors?

An offset account linked to your investment loan reduces the interest charged by offsetting the balance in the account against the loan. If you have $20,000 sitting in an offset account against a $500,000 loan, you only pay interest on $480,000.

Offset accounts are usually only available on variable rate loans. They are particularly useful for investors who receive rental income into the account, as the balance works to reduce interest without requiring you to pay down the loan directly. Redraw facilities allow you to access additional payments you have made, but they do not reduce daily interest in the same way an offset does.

Some lenders offer loan portability, which allows you to transfer the loan to a different property if you sell and purchase another investment within a short window. This can save on discharge and establishment fees. Other features to consider include the ability to make additional repayments without penalty, fee-free additional drawdowns if you want to access equity later, and the option to switch between interest-only and principal and interest without refinancing.

Not every feature adds value to every investor. If you are planning to hold one property for the long term and do not expect to make additional repayments, a basic loan with a lower rate may suit you better than a package with features you will not use.

How Rental Income Affects Borrowing Capacity

Lenders will include rental income when calculating what you can afford to borrow, but they do not count the full amount. Most lenders apply a discount of around 20 per cent to account for vacancy, maintenance and other holding costs, even if your property is currently tenanted.

If the property you are purchasing is expected to rent for $450 per week, the lender will typically assess it at $360 per week. That rental income is added to your other income and weighed against all your commitments, including the new loan repayment.

For Rosebud investors, rental yields vary depending on property type and location. Units close to the foreshore or within walking distance to cafes and parks generally attract consistent demand from long-term tenants and holiday renters, though short-term rental income is not always accepted by lenders in the same way as a residential lease. If you are relying on rental income to support your borrowing, make sure your broker is working with lenders who will recognise it in full.

Using Equity from Your Home to Fund the Deposit

Many Rosebud investors use equity in their existing home to fund the deposit on an investment property, rather than saving a separate cash deposit. If your home has increased in value and you have paid down some of the loan, you may be able to borrow against that equity without selling.

Lenders will allow you to borrow up to 80 per cent of your home's value in most cases, sometimes higher with Lenders Mortgage Insurance. If your home is worth $700,000 and you owe $350,000, you have $560,000 in total borrowing capacity at 80 per cent. After repaying the existing loan, you could access up to $210,000 in usable equity to put toward a deposit, stamp duty and other purchase costs.

Releasing equity does increase the debt on your home, and you will need to service both loans. The advantage is that you are not tying up cash, and the interest on the portion used to purchase the investment is generally tax deductible. Your accountant can confirm how the split should be recorded for tax purposes. Investors using equity often structure the loans separately so the investment portion remains clearly identified. A loan health check before you start can help clarify how much equity is available and whether your current loan structure supports this approach.

Tax Deductions and How Your Loan Structure Affects Them

Interest on an investment loan is generally tax deductible to the extent the loan is used to purchase or hold the rental property. Loan establishment fees, ongoing account fees, and costs such as valuation fees and mortgage insurance premiums may also be claimable, either immediately or over several years.

Keeping the investment loan separate from any personal borrowing is important. If you redraw funds from your investment loan to pay for a holiday or renovate your own home, that portion of the interest is no longer deductible. Similarly, if you use personal savings to pay down the investment loan and then redraw for personal use, you can lose the deduction on the amount redrawn.

The structure you choose at the outset determines how much flexibility you have later without affecting your tax position. Offset accounts preserve deductibility because the loan balance does not change, while additional repayments followed by redraw can create complications. We regularly see investors who have unknowingly reduced their tax benefit by using their investment loan for mixed purposes. Speak to your accountant before making changes to how your loan is set up or used.
