Redraw vs offset: what first-home buyers should know

Both offset accounts and redraw facilities reduce the interest you pay on your home loan. For first-home buyers seeing them for the first time, they can look interchangeable. They're not. Understanding the difference up front affects how much your loan costs you over its life.

Offset accounts

An offset is a transaction account that's linked to your loan. The balance in the offset reduces the loan balance the lender uses to calculate interest. Practically:

• Loan balance: $600,000
• Offset balance: $40,000
• Interest is calculated as if your loan is $560,000

You can deposit and withdraw from the offset like any everyday account — pay your bills, deposit your salary, run your spending through it. Every dollar that sits there reduces interest for the days it's there.

Why it suits many first-home buyers:

• Your salary works while it sits between paydays.
• Maximum flexibility — full access to the money at all times.
• Keeps the loan principal "clean" — useful if you might one day rent the property out.

Watch for: package or annual fees. Lenders often bundle offset into a package product that costs $300–400 a year. On a $600k loan with a $20k average offset balance, that's worth it. On a $30k average balance, less so.

Redraw facilities

Redraw works differently. You make extra repayments into the loan, and those extra payments sit inside the loan as a buffer against principal. You can later "redraw" the extras back out — but you're pulling them from the loan, not from a separate account.

Why it suits some first-home buyers:

• Usually free on basic loan products.
• The slight friction of redraw makes it harder to dip into casually.
• For someone with simple finances and no investment plans, it does the same job as offset at a lower cost.

Watch for: lender discretion. Banks can change redraw rules, freeze access, or apply withdrawal limits. Read the loan terms.

The decision

For most first-home buyers, the choice comes down to two questions:

1. Will the property potentially become an investment in the future? If yes, default to offset. Redraw can create tax complications if the loan is later used to fund a deductible asset.

2. Will you keep a meaningful balance in the offset (say $15k+ on average)? If yes, the package fee for offset pays for itself. If no, basic loan with redraw is cheaper overall.

The hybrid option

Some lenders allow split loans — part of the loan with offset, part without. This can be useful if you have a known lump sum (an inheritance, a bonus) you want to park efficiently, while keeping the rest of the loan structure simple.

The right answer is loan-specific. Worth modelling both setups on your actual numbers before settlement, not after.
