Unlock the secrets to Fixed, Variable & Split Investment Loans

The Decision You're Actually Making

When you're setting up finance for a Launceston rental property, the fixed versus variable question isn't about picking the loan with the lower rate today. You're deciding how much certainty you want around your repayments versus how much flexibility you need as your goals shift. A fixed rate locks your repayment for a set term, which helps when rental income needs to cover a known cost. A variable rate moves with the market, which can work in your favour when rates fall and gives you access to offset accounts and extra repayments without penalty. A split loan lets you hedge both ways.

The choice depends on whether you're holding the property for passive income now or building equity for your next purchase down the track. Both paths exist in the Launceston market, and both need different loan structures.

Fixed Rate Investment Loans: What You Gain and What You Give Up

A fixed rate gives you a set repayment for one to five years, regardless of what the Reserve Bank does. That certainty matters if your rental income sits close to your loan repayment and you need to budget without surprises. It also protects you if rates climb during your fixed term.

Consider a buyer who picks up a two-bedroom unit near the Launceston General Hospital precinct at $380,000 with a 20 per cent deposit. Rental yield in that pocket sits around 5 per cent, so weekly rent of roughly $365 covers part of the loan repayment. Fixing the rate at the time of settlement means the investor knows exactly what the shortfall will be each month, making it easier to plan for negative gearing or top-up from wages. If rates rise by half a percentage point in year two, the fixed rate holds and the investor avoids a repayment jump.

The trade-off is inflexibility. Most fixed rate products don't allow offset accounts, and extra repayments are capped at around $10,000 to $30,000 per year depending on the lender. If you sell or refinance before the fixed term ends, break costs apply. Those costs reflect the lender's funding loss and can run into thousands of dollars if rates have dropped since you locked in. For investors planning to sell within two years or refinance to access equity for a second purchase, a fixed rate can become a costly anchor.

Variable Rate Investment Loans: Flexibility With Moving Targets

Variable rates move when lenders adjust their pricing, which usually follows changes in the official cash rate or funding costs. Your repayment can fall when rates drop, and you'll typically have access to features that fixed loans don't offer: offset accounts, unlimited extra repayments, and no break costs if you refinance or pay out the loan early.

An offset account linked to your investment loan reduces the interest charged by the daily balance sitting in the account. If you're holding cash for the next deposit or building a buffer for vacancy periods, that balance works harder in an offset than in a separate savings account. The ability to make extra repayments also matters if you plan to switch from interest-only to principal and interest down the track or if your rental income exceeds expectations and you want to pay down debt faster.

The downside is repayment uncertainty. If rates climb, your cashflow tightens. For Launceston investors holding older homes with higher maintenance costs or properties in areas with seasonal vacancy, a variable rate adds another layer of unpredictability to an already variable income stream.

Split Loans: Dividing Your Loan Between Fixed and Variable

A split loan divides your borrowing into two portions, one fixed and one variable. You choose the split, commonly 50/50 but it can be any ratio that suits your circumstances. Each portion operates independently with its own rate, repayment schedule, and features.

In our experience, a split works when you want some repayment certainty without giving up all your flexibility. Fixing half your loan protects you from rate rises on that portion, while the variable half gives you access to an offset and the ability to make extra repayments. If you're planning to leverage equity within a few years to buy a second property, the variable portion can be paid down aggressively without triggering break costs, while the fixed portion holds your baseline repayment steady.

For a Launceston investor borrowing $400,000 to purchase a three-bedroom home in Newstead or Riverside, splitting $200,000 fixed and $200,000 variable means half the loan repayment stays predictable while the other half benefits from any rate cuts and accepts any offset balance you build. If rates drop, you benefit on half the loan. If they rise, you're protected on half. It's not perfect insurance, but it reduces the stakes on both sides.

Interest-Only Versus Principal and Interest on Investment Loans

Most investment loans start on interest-only terms for one to five years. You pay only the interest component, which keeps the repayment lower and maximises your deductions if you're negatively gearing. The loan balance doesn't reduce during that period, but your cashflow improves and you can direct surplus income toward your next deposit or offset balance.

Interest-only suits investors focused on portfolio growth rather than debt reduction. Once the interest-only term ends, the loan reverts to principal and interest and the repayment jumps. That reversion is manageable if rental income has increased, if you've refinanced to extend the interest-only term, or if you've sold and moved on. It becomes a problem if you're still holding the property, rents haven't moved, and your cashflow can't absorb a 30 to 40 per cent repayment increase.

Principal and interest from day one costs more each month but builds equity automatically. For investors who want to own the property outright or who expect stable rental income that can cover a higher repayment, it's a valid path. It's less common in the early years of an investment property purchase, but it's worth considering if your deposit is large, your rental yield is strong, or if you're uncomfortable carrying debt long-term.

How Loan Structure Affects Your Next Purchase

The loan structure you choose now will shape your borrowing capacity when you go back to the market. Lenders assess your uncommitted monthly income after all your expenses, including your investment loan repayment. If you're on interest-only, that repayment is lower and your serviceability is stronger. If you're on principal and interest, or if your fixed term has ended and your repayment has increased, your borrowing power contracts.

We regularly see this with Launceston investors looking to buy a second property within three to five years. If the first loan was structured with a long interest-only term and a variable rate that allowed offset, the investor can show the lender a healthy cash buffer, a manageable repayment, and access to equity without needing to refinance or break a fixed term. If the first loan was locked on a five-year fixed rate with no offset and principal and interest repayments, the investor either waits until the fixed term expires or wears the break cost to refinance and release equity.

Equity release depends on the property's current value and your loan to value ratio. Lenders typically allow you to borrow up to 80 per cent of the property's value without paying Lenders Mortgage Insurance. If your Launceston property has increased in value and your loan balance has stayed flat or reduced, the gap between the two is accessible equity. A variable loan or a split loan with a variable portion gives you the flexibility to access that equity without penalty. A fixed loan does not.

Tax Considerations and Recent Legislative Changes

Interest on an investment loan is deductible against your rental income and other assessable income under current rules. That deduction, combined with depreciation and other claimable expenses, often results in a net rental loss that offsets your salary or wage income. This is negative gearing, and it's been a core part of property investment strategy in Australia for decades.

From 1 July 2027, new rules apply. If you purchase a residential investment property on or after 7:30pm AEST on 12 May 2026, and it's not an eligible new build, your net rental losses can only be offset against other residential rental income or carried forward. You can't offset those losses against your wages. Properties purchased before that date, or eligible new builds, are not affected.

For Launceston investors, this shifts the maths. If you're buying an established home in Trevallyn or Prospect and expecting to negatively gear for the first few years, those losses will be quarantined from 1 July 2027 onward unless you already own the property. If you're buying a newly constructed dwelling on previously vacant land, or a property that increases the number of dwellings on the site, the old negative gearing rules still apply.

This doesn't make established properties unviable, but it does mean your cashflow needs to be tighter from the outset. Rental income needs to cover more of the repayment without relying on a tax refund to bridge the gap. That makes loan structure more important. A lower repayment through interest-only or a fixed rate that holds steady can make the difference between sustainable cashflow and monthly stress.

Choosing Between Fixed, Variable, and Split

Start with your plan. If you're holding the property for income and don't expect to refinance or sell within five years, a fixed rate gives you certainty without giving up much. If you're planning to buy again soon, access equity, or want the option to make large extra repayments, a variable rate keeps your options open. If you want both and can't decide which matters more, split the difference.

Your deposit size, rental yield, and tolerance for repayment movement all play a role. So does the Launceston market. Vacancy rates in some pockets are low and rental demand is steady, which supports predictable income. In other areas, particularly older homes further from the CBD or the university, vacancy can stretch longer and rental income becomes less reliable. A variable rate with an offset account gives you somewhere to park a buffer. A fixed rate without offset means that buffer sits elsewhere earning less.

There's no formula that works for every investor. The right structure is the one that matches where you're going, not the one with the lowest advertised rate this month. If you're not sure which that is, talking it through with someone who knows the Launceston market and sees how these loans perform over time will save you more than any rate discount.
