Variable Rate Loans: The Pros and Cons for Plasterers

What Is a Variable Rate Home Loan

A variable rate home loan charges interest that moves up or down based on lender decisions and official cash rate changes. When the Reserve Bank adjusts rates, most lenders follow within weeks. When your lender adjusts its own margins, your rate changes again. That means your repayment amount shifts over the life of the loan.

Variable rates typically come with more loan features than fixed rates. You usually get an offset account, unlimited extra repayments, and the option to redraw funds you've paid ahead. For plasterers who bill in cycles or take larger contracts intermittently, that flexibility matters. You can park a $30,000 payment from a commercial job in your offset account and reduce the interest charged on your loan balance without locking that cash away.

Consider a plasterer purchasing an established unit under the Australian Government 5% Deposit Scheme. They put down 5%, avoid LMI, and choose a variable rate home loan. Three months after settlement, they finish a large project and have $15,000 spare. They move it into their offset account. Interest is now calculated on the loan balance minus that $15,000. If they need to pull it out for a ute repair or materials for the next job, they can access it the same day.

Variable Rate Loan Features That Matter for Self-Employed Plasterers

Offset accounts and redraw facilities both let you reduce interest, but they work differently. An offset account is a separate transaction account linked to your loan. Every dollar in that account reduces the balance on which interest is calculated. Redraw lets you withdraw extra repayments you've already made into the loan itself. Some lenders limit redraw amounts or charge fees. Others don't.

If your income varies week to week, an offset account gives you more control. You can move money in and out without touching the loan structure. Redraw can be restricted during financial stress or if the lender changes its policy. For a plasterer working on quoted jobs with payment delays, that distinction matters. You don't want to find out your redraw is frozen when you need to cover payroll for a labourer.

Most variable rate loans also let you make unlimited extra repayments without penalty. That means if you have a profitable quarter, you can pay down the loan faster. On a fixed rate loan, extra repayments are often capped, and breaking the loan early triggers break costs that can run into thousands of dollars.

How Variable Rates Compare to Fixed Rates on Cost

Variable rates sit above fixed rates in some months and below them in others. Right now, lenders are pricing variable and fixed rates close to each other, but the gap shifts constantly. What matters more than the initial rate is how long you plan to stay on that loan structure and what you give up to lock in a fixed term.

A fixed rate protects you from rate rises for the fixed period, typically one to five years. But you lose offset access on the fixed portion, you're usually capped at $10,000 to $30,000 in extra repayments per year, and you pay break costs if you sell, refinance, or pay out the loan early. For plasterers who might want to upgrade, renovate, or access equity within a few years, those restrictions can cost more than a rate rise.

Some buyers split their loan, fixing part and leaving part variable. That gives you some rate protection and some flexibility. But it also means you're managing two loan accounts, two sets of terms, and two rate structures. It's not necessarily more complex, but it's worth understanding what you're signing up for before you commit.

What Happens When Rates Move

When the Reserve Bank lifts the cash rate, your variable rate typically rises within a few weeks. When the cash rate drops, your rate usually falls, though lenders don't always pass on the full cut. The repayment change depends on your loan size, your remaining term, and how much the rate moved.

On a loan balance of around $400,000, a 0.25% rate rise might add roughly $60 to $70 per month to your repayment. That's not catastrophic, but it's also not nothing if you're managing irregular income. If rates rise three or four times in a year, those increases stack up. That's why most lenders now assess your application at a buffer rate well above the actual rate you'll pay. If you're approved, you should be able to handle moderate rate increases without financial stress.

You can't control rate movements, but you can control how much buffer you leave in your budget. If your repayment sits at 25% of your gross income and rates rise by 1%, you're in a different position than someone already at 35%. The lower your starting repayment as a percentage of income, the more room you have to absorb increases.

Using the 5% Deposit Scheme with a Variable Rate Loan

The Australian Government 5% Deposit Scheme lets you buy with a 5% deposit and no LMI. Applications go through participating lenders, and each lender offers different loan products under the scheme. Some lenders offer variable rate loans with full offset and redraw. Others offer basic variable loans with limited features. You need to confirm what's available with your lender before you apply.

The scheme has no income cap, which matters for plasterers whose income can look lumpy on paper. You might have a strong year followed by a slower year, or you might be building your business and showing lower taxable income while you reinvest. The scheme doesn't block you for earning too much or too little. It just requires that you're buying your first home, you're an Australian citizen or permanent resident, and the property sits under the price cap for your state or territory.

For a plasterer buying an established home under the scheme, a variable rate loan gives you the flexibility to pay down the loan faster when work is steady and access funds when it's not. That suits the way most tradies actually earn.

First Home Buyer Stamp Duty Concessions Across States

Stamp duty concessions vary by state, and they can save you thousands or tens of thousands of dollars depending on where you buy. In New South Wales, first home buyers pay no stamp duty on properties up to $800,000 and get a concession on properties between $800,001 and $1,000,000. In Victoria, the exemption applies up to $600,000 with a concession to $750,000. Queensland offers a full concession on new homes with no price cap and a partial concession on established homes up to a value of around $709,999, depending on when you signed the contract.

In Western Australia, the rules changed in mid-2026. The regional and metro distinction was removed, and a single statewide threshold now applies. No duty is payable on homes valued up to $600,000, with a concessional rate on homes between $600,001 and $800,000. In South Australia, stamp duty relief applies to new homes and vacant land only, with no price cap for contracts from mid-2024 onward.

These concessions apply regardless of whether you choose a variable or fixed rate loan. But they do affect how much cash you need at settlement. If you're buying in New South Wales at $750,000 and you're exempt from stamp duty, that's around $28,000 you don't need to find upfront. That cash can go toward your deposit, your offset account, or your emergency buffer. For a plasterer managing variable income, having that extra liquidity matters more than it does for a salaried buyer.

What to Check Before You Apply

Before you apply for a home loan as a plasterer, check what loan features the lender actually offers on the product you're applying for. Not all variable rate loans come with offset accounts. Not all lenders let you redraw without fees. Some lenders cap extra repayments even on variable loans. Some charge monthly account fees. Some don't.

If you're self-employed, check what income documents the lender requires. Most lenders want two years of tax returns and two years of notices of assessment from the ATO. Some will accept one year if your income is strong and consistent. Some lenders offer low-doc loans, but those usually come with higher rates and lower maximum loan-to-value ratios. If you've been trading for less than two years, your options narrow, but they don't disappear. Some lenders will still assess you if you've been in the trade for several years and can show consistent contracts or invoicing.

You also need to know how the lender assesses your income. Some lenders add back depreciation and other non-cash deductions. Others don't. Some average your taxable income over two years. Others take the lower year or apply a haircut. That assessment method determines your borrowing capacity, which determines what you can actually buy. If one lender tells you that you can borrow $450,000 and another says $520,000, the difference is usually in how they treat your tax return.

When a Variable Rate Loan Makes Sense

A variable rate loan suits you if you want full control over extra repayments, if you value offset access, or if you think you might sell, refinance, or pay down the loan faster than the standard 30-year term. It also suits you if you're not particularly worried about rate rises or if you've built enough buffer into your budget to handle them.

It's less suited to you if you want payment certainty, if you're already stretching your budget, or if a rate rise of even 0.5% would put you under pressure. In that case, a fixed rate or a split loan might make more sense. But if that's your situation, the real issue isn't the loan structure. The real issue is that you're borrowing too much.

For most plasterers buying your first home, a variable rate loan offers the flexibility you actually need. Rates will move. Your income will move. Your repayment capacity will move. A variable rate loan moves with you. A fixed rate loan doesn't.
