Beginner's Guide to Variable Rate Loans for SA Buyers

Variable Rate Loans Give You Flexibility That Matches Where You Are Right Now

A variable rate loan adjusts when lenders change their rates. Your repayments can go up or down depending on market movements. For first home buyers in South Australia, this flexibility often comes with features like offset accounts and unlimited extra repayments that can make a real difference to how quickly you pay down your loan.

Most first home buyers in SA who choose a variable rate do so because they want the option to make extra repayments without penalty, or because they're planning to pay off their loan faster once they have more income to spare. The offset account is another reason. Every dollar sitting in your linked transaction account reduces the interest charged on your home loan, which can save you thousands over the life of the loan.

How Variable Rates Work in Practice

When the Reserve Bank changes the cash rate, most lenders adjust their variable rates within a few weeks. Your repayment amount changes with it. If rates drop, you pay less. If rates rise, you pay more. This means your budget needs to accommodate potential increases.

Consider a buyer in Adelaide's northern suburbs purchasing at the area's current median with a 10% deposit. They take out a variable rate loan with an offset account. They start by making minimum repayments, but within two years their household income increases and they begin directing an extra few hundred dollars a month into their offset account. That balance reduces the interest charged each month, which means more of each repayment goes toward the principal. Over five years, that approach can reduce the loan term significantly compared to making minimum repayments alone.

Features That Make Variable Loans Worth Considering

Variable rate loans typically include an offset account, redraw facility, and the ability to make unlimited extra repayments. Not all lenders offer all three, so it's worth comparing what's included before you commit.

An offset account functions like a transaction account. Your salary goes in, your bills come out, and whatever balance remains offsets the interest charged on your home loan. If you have a loan balance of $400,000 and $10,000 in your offset account, you're only charged interest on $390,000. You still have access to that $10,000 whenever you need it.

A redraw facility lets you access extra repayments you've made on your loan. If you've paid an additional $5,000 over the last year and you need that money for something urgent, you can withdraw it. Some lenders charge a redraw fee, others don't. Some cap the number of redraws you can make each year.

Using SA First Home Buyer Support with a Variable Rate Loan

South Australia offers a $15,000 first home owner grant for new homes with no property price cap for contracts entered into from 6 June 2024. Stamp duty relief is also available on new homes and vacant land with no price cap for the same period. These concessions do not apply to established homes.

You can combine the SA grant and stamp duty relief with the Australian Government 5% Deposit Scheme. That scheme lets you purchase with a 5% deposit without paying Lenders Mortgage Insurance. Both the purchase price and the lender's assessed value must fall within the applicable price cap. For South Australia, that cap is $900,000 for capital city and regional centres, and $500,000 for other areas.

In a scenario where a buyer is purchasing a new home in a regional centre like Mount Gambier, they could access the $15,000 grant, pay no stamp duty on the purchase, and borrow with a 5% deposit under the federal scheme. The variable rate loan structure would give them flexibility to make extra repayments as their income grows, which is particularly useful for buyers in regional areas where employment opportunities can expand over time.

When a Variable Rate Loan Might Not Suit Your Situation

If your budget is tight and you can't afford any increase in repayments, a variable rate loan may add too much uncertainty. Rate rises can happen quickly, and repayments can jump by hundreds of dollars a month depending on the size of your loan.

Some buyers prefer the certainty of a fixed rate for the first few years, particularly if they're stretching their budget to enter the market. A fixed rate locks in your repayment amount for a set period, usually between one and five years. You won't benefit if rates fall, but you also won't be exposed if rates rise. Fixed rates generally don't include offset accounts, and most lenders restrict extra repayments during the fixed period.

Another option is a split loan, where part of your loan is fixed and part is variable. You get some certainty on repayments and some flexibility to make extra repayments or use an offset account. Split structures can be useful if you're not sure which direction rates are heading or if you want to test both approaches before committing fully to one.

What Lenders Look at When You Apply for a Variable Rate Loan

Lenders assess your income, expenses, existing debts, and deposit size. They also apply a buffer to the current variable rate when calculating how much you can borrow. That buffer is usually around 3%, which means even if the current rate is lower, the lender tests whether you could still afford repayments if rates increased.

If you're applying under the 5% Deposit Scheme, your application goes through a participating lender. Not all lenders participate in the scheme, so your choice of lender may be narrower than if you were applying with a larger deposit. Participating lenders assess your application under their usual criteria, but the scheme removes the need for LMI, which can save you thousands in upfront costs.

Your deposit can include genuine savings, the First Home Super Saver Scheme, or a gift from a family member. Most lenders require at least part of your deposit to come from genuine savings, which means money you've held in your account for at least three months. Some lenders accept a gift for the full deposit if it's accompanied by a signed declaration from the person providing it.

Applying for a Variable Rate Loan as a First Home Buyer in SA

You'll need proof of income, recent bank statements, identification, and details of any debts or liabilities. If you're purchasing a new home and applying for the SA first home owner grant, you'll also need to complete the grant application through RevenueSA. That application is usually submitted after you've signed the contract but before settlement.

Pre-approval gives you a clear idea of how much you can borrow before you start looking at properties. It's not a guarantee, but it does mean a lender has assessed your financial position and confirmed they're willing to lend to you subject to a property valuation and final checks. Pre-approval is valid for three to six months depending on the lender, and it can make your offer more appealing to vendors because it shows you've already secured finance in principle.

Once you've found a property and signed a contract, you move to formal approval. The lender orders a valuation, reviews the contract, and confirms the loan. Settlement usually occurs four to eight weeks after contracts are exchanged, depending on what's negotiated in the contract.
