Understanding the basics of home loans and ownership

Owning property in South Perth is something many people work towards. The choice between variable, fixed or split rate structures can shape how you manage repayments, and knowing which loan features suit your situation helps you move forward with confidence.

How variable rate loans work in practice

A variable rate loan adjusts when the lender changes its interest rate. Your repayments go up or down accordingly. If the Reserve Bank lowers the cash rate and your lender follows, your monthly payment reduces. If rates rise, so does your repayment. Most variable rate products include an offset account, which is a transaction account linked to your loan. The balance in that account reduces the interest charged on your loan balance. If you have a loan of $500,000 and $20,000 sitting in your linked offset, you only pay interest on $480,000. That can shorten your loan term or reduce the total interest paid over time. Some variable home loans also allow extra repayments without penalty, which can help you build equity faster if your budget allows.

Fixed rate loans and when they make sense

A fixed interest rate home loan locks in your rate for a set period, usually between one and five years. Your repayment amount stays the same during that time, which can make budgeting more predictable. Fixed rate products generally don't include an offset account, and most lenders cap how much extra you can repay each year without triggering a break cost. If you need to sell or refinance during the fixed term, you may be charged an early exit fee. That fee is calculated based on the difference between your fixed rate and the lender's cost to replace your loan in the wholesale market. Consider a buyer who locked in a three-year fixed rate and then needed to sell two years later because of a job relocation. The break cost in that scenario was close to $8,000, which came out of the sale proceeds.

Split rate structures for those wanting both

A split loan divides your loan amount across two portions: part fixed, part variable. You might fix 50 per cent of your loan for three years and keep the other 50 per cent variable with an offset account attached. This gives you rate certainty on half your debt while keeping flexibility on the other half. In our experience, split structures work well for buyers who want some protection against rate rises but still want access to an offset and the ability to make extra repayments. The fixed portion provides stability, and the variable portion gives you room to pay down the loan faster when your income allows. Each portion of the loan is treated separately, so you can usually access redraw or offset features on the variable side without restriction.

Principal and interest versus interest only

Most owner occupied home loans are structured as principal and interest, which means each repayment covers both the interest charged and a portion of the loan balance. Over time, you reduce what you owe and build equity in the property. Interest only loans, where you pay only the interest charged each month, are more common for investment properties. On an interest only loan, your repayment is lower because you're not reducing the principal, but you don't build equity through repayments. At the end of the interest only period, which is typically one to five years, the loan reverts to principal and interest and your repayment increases. Some lenders offer interest only periods on owner occupied loans, but eligibility is stricter and you'll need to demonstrate a clear reason, such as managing cash flow during a career transition.

Offset accounts and how they reduce interest

An offset account is one of the most useful features on a variable rate loan. It's a transaction account that sits alongside your home loan. Every dollar in that account offsets the balance of your loan when the lender calculates interest. If your loan balance is $600,000 and you have $30,000 in your offset, you're charged interest on $570,000. The interest saving is the same as if you'd made a $30,000 extra repayment, but the cash stays accessible. You can use it for expenses, emergencies or future plans without needing to redraw from the loan. Not all lenders offer a full 100 per cent offset. Some offer partial offsets, where only a percentage of your account balance is counted. Check the terms before you commit.

Loan to value ratio and borrowing capacity

Your loan to value ratio, or LVR, is the loan amount expressed as a percentage of the property value. If you're borrowing $450,000 to buy a property valued at $600,000, your LVR is 75 per cent. Lenders use LVR to assess risk. An LVR above 80 per cent usually means you'll need to pay Lenders Mortgage Insurance, which protects the lender if you default. LMI is a one-off cost added to your loan or paid upfront, and it can range from a few thousand dollars to over $20,000 depending on your loan amount and LVR. The Australian Government 5% Deposit Scheme can help eligible first home buyers avoid LMI by providing a government guarantee to the lender, allowing you to borrow with a deposit as low as 5 per cent. South Perth properties within the Perth metropolitan area are subject to the $850,000 price cap under that scheme. Your borrowing capacity is the maximum amount a lender will let you borrow, and it's influenced by your income, expenses, existing debts and the serviceability buffer. Lenders assess your ability to service a loan at a rate 3 percentage points above the actual product rate, so if you're applying for a variable rate loan currently offered at 6.2 per cent, the lender will test your repayments at 9.2 per cent.

Pre-approval and how it helps you plan

Home loan pre-approval gives you a conditional commitment from a lender before you start looking at properties. The lender reviews your income, expenses, debts and credit history, then tells you how much you can borrow. Pre-approval is usually valid for three to six months. It doesn't lock in an interest rate, but it does give you a clear budget and shows sellers you're a serious buyer. In a suburb like South Perth, where properties close to the Swan River or Mends Street precinct move quickly, having pre-approval can make the difference between securing a property and missing out. A pre-approval is conditional on a satisfactory property valuation and final credit assessment, so it's not a guarantee, but it gives you a strong starting point when you find the right place.

Comparing home loan options and rates

When you compare rates, look beyond the advertised interest rate. The comparison rate includes most fees and charges, giving you a clearer picture of the loan's true cost over a standard loan term. A loan with a low advertised rate but high ongoing fees might cost more over time than a loan with a slightly higher rate and lower fees. Some lenders offer rate discounts if you have other products with them, such as a transaction account or credit card, or if you make a larger deposit. Rate discounts can reduce your interest rate by 0.10 to 0.50 percentage points, depending on the package. When you compare rates, also consider the loan features that matter to you. A loan with a lower rate but no offset or limited extra repayment options may not suit your situation as well as a loan with a slightly higher rate and more flexibility. A mortgage broker can help you access home loan options from banks and lenders across Australia, including products not advertised directly to the public.

Western Australian first home buyer concessions

Western Australia removed the geographic distinction between Perth and regional areas from 7 May 2026, so all first home buyers in the state now access the same duty thresholds. No duty is payable on homes valued up to $600,000, and a concessional rate applies on homes valued between $600,001 and $800,000. The First Home Owner Grant of $10,000 applies to new homes valued up to $800,000 south of the 26th parallel, which includes South Perth. The grant doesn't apply to established homes. These concessions can reduce the upfront cost of buying and free up cash for your deposit or other expenses. You need to occupy the property as your principal place of residence for at least six continuous months within 12 months of settlement to retain eligibility.
