A loan structure determines what you pay over 30 years more than the interest rate does.
Melbourne borrowers typically compare rates and take the lowest number. The offset account sits unused. The redraw gets ignored. The split option never comes up. Then five years in, someone mentions a feature that would have saved $40,000, and it's too late to add it without refinancing.
Offset Accounts vs Redraw: The Difference in Access
An offset account reduces interest daily based on your balance without locking funds into the loan. Every dollar in the offset account reduces the amount your interest is calculated on, which cuts both the interest you pay and the loan term if you maintain repayments. A redraw facility lets you take back extra repayments, but the lender controls access and can restrict or remove it.
Consider a buyer with a $600,000 loan at variable rates who keeps $30,000 in savings. With a linked offset, that $30,000 offsets the loan balance daily and saves roughly $1,800 per year in interest. With redraw, the same $30,000 sits in a separate savings account earning minimal interest while the full $600,000 accrues loan interest. Redraw works if you're disciplined about extra repayments and rarely need access. Offset works if you want liquidity and automatic interest reduction without effort.
Fixed Rate, Variable Rate, or Split: Matching Structure to Intent
Fixed rates lock your rate for one to five years, which removes uncertainty but limits flexibility. Variable rates move with the market and allow unlimited extra repayments, redraw, and offset in most cases. A split loan divides your borrowing between fixed and variable, giving partial rate protection and partial flexibility.
A split works when rate stability matters but you still want access to features. We regularly see Melbourne buyers split 50/50 or 60/40 fixed to variable, depending on whether they value certainty or control. The fixed portion covers the minimum repayment. The variable portion absorbs extra repayments and connects to the offset account. The structure costs nothing extra to set up and prevents the situation where you're locked into a fixed rate but receiving a bonus or inheritance with nowhere to put it except a low-interest savings account.

Principal and Interest vs Interest-Only: The Trade in Equity
Principal and interest repayments reduce the loan balance each month, which builds equity and lowers total interest. Interest-only repayments cover only the interest charged, leaving the loan balance unchanged. The monthly repayment is lower, but the loan doesn't reduce unless you make voluntary repayments.
Interest-only makes sense for investors holding property in areas with strong capital growth or for owner-occupiers managing cash flow during parental leave or business setup. It doesn't make sense as a long-term strategy for an owner-occupied property unless there's a specific reason you need to preserve capital in the short term. Most lenders allow interest-only for up to five years, after which the loan reverts to principal and interest. The repayment jump at reversion is often larger than borrowers expect, particularly if rates have moved.
Portability: Taking Your Loan When You Move
A portable loan lets you transfer your existing loan to a new property without breaking the contract or paying discharge fees. You keep the same rate, the same loan terms, and the same features. If you're on a fixed rate and the market has moved higher, portability can save thousands in break costs and rate differences.
Not all lenders offer portability, and those that do often limit it to specific products. In Melbourne's inner and middle-ring suburbs, where buyers often upgrade within five years, portability turns a fixed rate from a restriction into a tool. You get rate certainty without the penalty of being locked in if your circumstances change. It's worth checking before you settle, not after you've accepted an offer on your next property.
Extra Repayments and Redraw Limits: Reading the Terms
Most variable rate loans allow unlimited extra repayments with full redraw access. Some low-rate products cap extra repayments at $10,000 or $20,000 per year without penalty. Others allow extra repayments but restrict redraw to specific amounts or frequencies.
The restriction matters if you're planning to use your loan as a cash flow tool. A buyer who directs their salary into a loan with unlimited redraw and a linked offset can reduce interest daily and still access funds for settlement, renovations, or investment deposits. A buyer on a product with redraw restrictions can make extra repayments but has to apply each time they want access, and the lender can decline. The difference isn't clear in the rate comparison. It shows up when you try to access your own money.
Loan Splits Across Multiple Properties: Structure for Investors
A loan split lets you divide your borrowing into separate accounts, each with its own rate type, feature set, and purpose. Investors use splits to separate owner-occupied debt from investment debt, which keeps interest deductibility clear and simplifies tax reporting.
A Melbourne buyer purchasing an investment property in Footscray while living in Richmond might structure the loan as two splits: one for the owner-occupied portion with an offset account, one for the investment portion on interest-only with no offset. The structure costs nothing to set up and prevents cross-contamination of funds, which the ATO will question if you're claiming interest deductions. It also makes refinancing simpler later, because you can move one split without touching the other.
Rate Discounts and Package Fees: The Real Cost
Some lenders offer rate discounts in exchange for an annual package fee, typically $300 to $400. The package might also include fee waivers on credit cards, transaction accounts, or offset accounts. Whether the package saves money depends on the size of your loan and the discount offered.
A discount of 0.20% on a $600,000 loan saves $1,200 per year in interest, which makes a $395 package fee worthwhile. A discount of 0.10% saves $600, which doesn't. The calculation changes as your loan balance reduces. A package that made sense at settlement might cost more than it saves five years in. Most borrowers pay the fee every year without checking.
Lenders Mortgage Insurance and Loan Features: The LVR Threshold
Borrowing above 80% of the property value triggers Lenders Mortgage Insurance, which protects the lender if you default. LMI is a one-off cost added to your loan balance, and it doesn't entitle you to additional features. Some lenders restrict offset accounts, split loans, or extra repayment flexibility on loans above 90% LVR.
The restriction matters if you're borrowing at 90% or 95% and expecting full access to features. A buyer borrowing $570,000 to purchase in Melbourne's outer suburbs at 95% LVR might find their loan doesn't include an offset account or allows only one split. The lender isn't required to disclose this during pre-approval, and the borrower doesn't find out until the loan documents arrive. Checking feature availability at high LVR before committing to a lender prevents the situation where you've paid LMI but don't have the features you need.
Loan Portability and Fixed Rate Break Costs: The Overlap
Breaking a fixed rate early usually triggers a break cost, which compensates the lender for the difference between your fixed rate and the current wholesale rate. The cost can be zero if rates have risen, or tens of thousands if rates have fallen. A portable loan avoids break costs entirely by transferring the existing loan to the new property.
Not all lenders allow portability, and those that do usually require the new property to be of equal or greater value. The borrower can top up the loan if needed, but can't reduce it without triggering a partial break cost. For Melbourne buyers moving from an apartment in Southbank to a house in Kew, portability keeps the fixed rate intact and avoids a break cost that could exceed $15,000. The feature has no ongoing cost, but most borrowers don't know to ask for it.

Frequently Asked Questions
What is the difference between an offset account and a redraw facility?
An offset account reduces your loan interest daily based on your balance and gives you full access to your funds at any time. A redraw facility lets you withdraw extra repayments you've made, but the lender controls access and can restrict or remove it.
Should I choose a fixed, variable, or split home loan?
Fixed rates lock your rate for one to five years and remove uncertainty but limit flexibility. Variable rates move with the market and allow extra repayments and offset accounts. A split loan divides your borrowing between both, giving partial rate protection and partial flexibility.
What is a portable home loan and when does it matter?
A portable loan lets you transfer your existing loan to a new property without breaking the contract or paying discharge fees. It matters most if you're on a fixed rate and want to move properties without triggering break costs.
Do high LVR loans have the same features as low LVR loans?
Not always. Some lenders restrict offset accounts, split loans, or extra repayment flexibility on loans above 90% LVR. Checking feature availability before committing to a lender prevents surprises at settlement.
Is a loan package fee worth paying for a rate discount?
It depends on your loan size and the discount offered. A discount of 0.20% on a $600,000 loan saves $1,200 per year, which makes a $395 package fee worthwhile. A smaller discount may not cover the fee.
