Smart ways to approach home loan comparison

Comparing home loans based on rate alone misses most of what determines value

The lowest advertised rate rarely delivers the lowest cost once you factor in offset access, redraw restrictions, and whether the loan lets you hold it through property changes without refinancing. A loan that charges 0.15% more but includes a full offset account will often save you more interest over five years than a stripped-back product with a headline rate that looks lower on paper.

Consider a buyer in Mount Eliza who locks in a low rate on a basic variable loan without offset. They keep their savings in a separate account earning minimal interest while paying the full loan rate on the entire balance. A borrower with an offset account paying a slightly higher rate but parking their savings in offset effectively reduces their loan balance for interest calculation purposes. Over time, that structure costs less despite the higher rate.

What offset accounts actually do to your interest bill

An offset account is a transaction account linked to your home loan where the balance reduces the amount of interest you're charged. If you have a loan amount of $500,000 and $30,000 sitting in a linked offset, you're only charged interest on $470,000. The savings compound because you're not taxed on the interest you're not paying, unlike the interest you'd earn in a savings account.

Not all offset accounts work the same way. Some lenders offer partial offset, where only a percentage of your savings balance is used to reduce interest. Others link one offset to multiple loans, which matters if you're planning to keep an investment loan and an owner occupied home loan under the same structure. The difference in how offset is structured can shift the value calculation between two loans that otherwise look similar.

Fixed rate versus variable rate is about certainty, not savings

You choose a fixed interest rate when repayment certainty matters more than potential savings. A fixed rate home loan locks your interest rate for a set period, usually between one and five years. During that time, your repayments don't change regardless of what happens to variable home loan rates. You give up flexibility in return for knowing exactly what you'll pay.

Variable rate loans move with the lender's standard variable rate, which shifts in response to the Reserve Bank's cash rate and the lender's own funding costs. When rates drop, your repayments drop. When rates rise, so do your repayments. Variable loans typically allow extra repayments and full redraw without penalty. Fixed loans often limit extra repayments to a set amount per year and charge break costs if you exit early.

A split loan divides your loan amount between fixed and variable portions. You might fix 50% at the current rate and leave 50% variable. The fixed portion gives you repayment stability, and the variable portion gives you flexibility to make extra repayments and take advantage of rate drops. The split doesn't need to be even. You can weight it based on how much certainty you want versus how much flexibility you need.

Interest only loans are a cash flow tool, not a long-term structure

An interest only loan requires you to pay only the interest each month, not the principal. Your loan balance doesn't reduce, but your repayments are lower. This structure suits investors who want to maximise cash flow and claim the interest as a tax deduction, or buyers who need lower repayments temporarily while income is variable or while they're managing another financial commitment.

Most lenders offer interest only periods of up to five years on owner occupied home loans and up to ten years on investment properties. At the end of that period, the loan reverts to principal and interest unless you apply to extend it. Your repayments increase significantly when the loan reverts because you're now repaying both interest and principal over the remaining loan term. Interest only makes sense when you have a specific reason to keep repayments low and a plan for what happens when the period ends.

Rate discounts depend on loan size, deposit, and whether you're refinancing

The interest rate you actually get is not the rate advertised. Lenders apply rate discounts based on the size of your loan amount, your loan to value ratio, and whether you're a new customer refinancing from another lender. A $300,000 loan at 80% LVR might receive a smaller discount than a $600,000 loan at the same LVR. The discount can range from 0.10% to over 1.00% depending on the lender's current appetite for new business.

Some lenders also offer relationship discounts if you hold other products like credit cards, transaction accounts, or insurance with them. Others reserve their lowest rates for borrowers who meet a package fee, which might be $395 per year in return for a rate that's 0.70% lower. Whether the package fee makes sense depends on your loan size. On a $400,000 loan, a 0.70% discount saves you roughly $2,800 in the first year, so the $395 fee is worthwhile. On a $150,000 loan, the saving might only be $1,050, and the fee becomes a larger percentage of that benefit.

Portability and discharge fees matter when your situation changes

A portable loan lets you transfer the existing loan to a new property without refinancing. If you're planning to sell and buy again within a few years, portability saves you from paying discharge fees, application fees, and potentially Lenders Mortgage Insurance again if your deposit drops below 80% on the new purchase. Not all lenders offer portability, and those that do often limit it to like-for-like transactions where the new property is the same security type as the old one.

Discharge fees are what the lender charges to release the mortgage when you sell or refinance. They typically range from $150 to $400, but some lenders waive them if you're refinancing internally or if you've held the loan for a certain period. If you're in Mount Eliza and likely to move within five years, either for work or to upsize as your family grows, checking portability and discharge terms before you apply for a home loan avoids a surprise cost later.

Redraw restrictions limit access to extra repayments

Redraw lets you access extra repayments you've made above the minimum. If your minimum repayment is $2,500 per month and you've been paying $3,000, the extra $500 each month builds up in your loan as available redraw. Some lenders let you access that money anytime with no fee. Others set a minimum redraw amount, charge a fee per transaction, or limit how often you can redraw.

In our experience, redraw restrictions catch people out when they assume their extra repayments are as accessible as money in a savings account. A lender might allow unlimited free redraws online but charge $50 for a redraw processed over the phone or at a branch. Others might let you redraw as often as you like on a variable loan but lock redraw completely on a fixed rate home loan. If you're making extra repayments as a way to build a buffer for future expenses, check the redraw terms in detail before you commit.

Comparing home loan features using a broker gives you access to more products

Most borrowers compare home loan products by looking at two or three banks they already know. A broker compares home loan options from lenders you've never heard of alongside the major banks, and structures the loan to match your situation rather than fitting you into a standard product. The broker's comparison includes rate, offset, redraw, portability, and package fees, and shows you the total cost over the period you're likely to hold the loan.

A broker also handles the home loan application and liaising with the lender, which matters more when your situation involves anything outside straightforward full-time employment and a single property purchase. If you're self-employed, refinancing with multiple debts to consolidate, or buying in Mount Eliza while selling in another state, the broker's value is in structuring the application so it meets lender policy without unnecessary delays. Brokers at Blank Financial work with clients across Australia and have access to home loan packages from over 30 lenders, which includes banks, credit unions, and non-bank lenders that don't advertise directly to consumers.

How to decide which loan features you actually need

Start with how you'll use the loan. If you're buying an owner occupied home and you keep a buffer of savings for emergencies or upcoming expenses, you need an offset account more than you need the absolute lowest rate. If you're an investor focused on building equity through capital growth and you won't be making extra repayments, offset doesn't matter and you should prioritise rate and flexibility to make interest only repayments.

If your income is stable and you want repayment certainty, a fixed rate home loan or split loan makes sense. If your income varies, or you're planning to make lump sum repayments from bonuses or sale proceeds, a variable rate with full redraw and no offset fees gives you the flexibility to pay down the loan faster without penalty. The right structure depends on whether you value certainty, flexibility, or cost reduction most, and that priority shifts depending on your life stage and what you're trying to achieve with the property.
