Free: Home Loan Structure Review

We'll review your current or upcoming loan structure and confirm you have the right offset/redraw setup for your situation.

When choosing a home loan, you'll almost certainly be asked: "Do you want an offset account, redraw facility, or both?" Most people choose without fully understanding the difference — which can lead to the wrong loan structure for their situation.

Both features save you interest. But they have different implications for accessibility, flexibility, and tax — especially if you ever plan to turn your home into an investment property.

Head-to-Head Comparison

FeatureOffset AccountRedraw Facility
How it worksSeparate transaction account; balance offsets your loan principalExtra repayments sit inside the loan; you can withdraw them back
Interest savedOn every dollar in the offset accountOn every dollar of extra repayments made
AccessibilityInstant — like any bank account (debit card, BPAY)Usually instant online; some lenders may have minimum amounts or delays
Lender can restrict access?No — it's your own bank accountYes — in hardship or lender policy change, redraw can be suspended
Interest calculationDaily on (loan balance minus offset balance)Daily on (loan balance minus extra repayments)
Available on variable rate loansYes (most)Yes (most)
Available on fixed rate loansRarely (some limited offset)Usually no (or very limited)
Loan feeUsually comes with a package fee ($395–$750/year)Usually free on basic variable loans
Tax implicationsFunds remain your money — no tax issue when withdrawnRedrawing for personal use while loan is used for investment can affect deductibility

Worked Example: How Both Save Interest

Same scenario, two structures:

  • Loan: $600,000 at 6.00% p.a. variable
  • Savings: $50,000
Offset AccountRedraw
Loan balance$600,000$600,000 (less $50K extra repayments = $550,000 effective)
Balance interest charged on$550,000$550,000
Daily interest saved$50,000 × 6% ÷ 365 = $8.22/day$50,000 × 6% ÷ 365 = $8.22/day
Annual interest saved~$3,000~$3,000

The interest saving is identical. The difference is entirely in how you access, control and use the funds.

The Tax Trap: Why Investors Must Choose Carefully

This is the most important distinction — and the one most people miss.

The redraw problem for future investors: If you buy a home to live in, overpay your loan (building a redraw balance), then later decide to rent it out and buy another property — any money you redraw for personal use while the property is now an investment reduces the tax-deductible portion of the loan. This is a well-known ATO trap.
How offset avoids this: Money in an offset account is separate from the loan. When the property becomes an investment, the loan balance (which is what's deductible) is unchanged by your offset balance. You can withdraw from your offset for personal reasons without affecting loan deductibility at all.

This is why most mortgage brokers recommend an offset account over redraw for anyone who might eventually convert their home to an investment property — even if that's 5–10 years away.

When Redraw Makes Sense

Despite the tax caveat, redraw is a perfectly good feature in the right scenario:

  • You're on a basic variable rate loan with no package fee — the interest saving is the same, just without the annual package cost
  • You're certain you'll never convert to an investment property
  • You want to build equity faster without maintaining a separate account to manage
  • Your lender's offset comes with a higher rate that offsets the benefit

Decision Guide

Your situationBest choice
Owner-occupier; no plans to investRedraw (basic variable; lower fee) or offset (if package rate is competitive)
Owner-occupier; might invest laterOffset — future-proof your tax position
Investor from day oneOffset — protects loan deductibility
Fixed rate loanNeither fully available — consider split loan (fixed + variable with offset)
Want maximum flexibilityOffset — instant access, no lender restrictions

FAQs

An offset account is a transaction bank account linked to your mortgage. The balance offsets your loan principal for the purpose of interest calculation. If your loan is $500,000 and your offset has $50,000, you pay interest only on $450,000. The full $500,000 is still owing — you're just not being charged interest on the offset portion.
A redraw facility lets you access extra repayments you've made above the minimum. If your minimum is $2,500/month and you pay $3,000, the extra $500 reduces your loan balance — and is available to redraw if needed. The interest saving comes from the reduced loan balance, not from a separate account.
Both save exactly the same amount of interest, dollar for dollar, for the same balance. The difference is entirely in how you access, control, and use the funds — not in the interest saved. The tax implications are the most meaningful practical distinction.
Yes, typically. Funds in an offset account remain separate from the loan — so they don't affect the deductible loan balance when the property becomes an investment. Funds redrawn from a redraw facility and used for personal purposes reduce the deductible loan balance, which reduces your tax deduction. Your accountant can confirm how this applies to your specific situation.
