Buying your next home means choosing a loan structure that fits how you'll use the property and what you're planning beyond this purchase.
If you're moving from one owner-occupied property to another, refinancing out of an investment loan to live in the property, or keeping your current place as a rental while buying elsewhere, the loan you select now affects your borrowing capacity and tax position for years ahead. The structure you lock in at settlement is harder to change later without refinancing costs, so getting it right from the start matters.
Owner Occupied vs Investment: The Structure That Shapes Your Options
Your loan structure depends on whether you'll live in the property or rent it out. An owner occupied home loan typically offers lower interest rates than an investment loan because lenders view it as lower risk. The rate difference is usually 0.30% to 0.60%, which on a $500,000 loan translates to around $1,500 to $3,000 more in interest each year if you structure it as investment when you don't need to.
If you're keeping your current home as a rental and buying elsewhere to live in, your new purchase should be structured as owner-occupied. In our experience, buyers sometimes assume the larger loan should be investment because the rental property has the higher value, but the classification follows occupancy, not loan size. Getting this wrong can cost you thousands in unnecessary interest and limit your ability to claim deductions on the property you're actually renting out.
Fixed Rate, Variable Rate, or Split: Matching Rate Type to Your Situation
A variable rate moves with the market and gives you full access to offset accounts and unlimited additional repayments. A fixed interest rate home loan locks your rate for a set period, usually one to five years, but typically restricts extra repayments to around $10,000 to $30,000 per year depending on the lender.
A split loan divides your loan amount between fixed and variable portions. Consider a buyer purchasing a $650,000 home in Redlands with a $520,000 loan. They expect a $40,000 inheritance within two years and want some rate certainty while keeping flexibility to pay down debt when the money arrives. A 50/50 split lets them fix half the loan for three years while keeping $260,000 variable with a full offset account. When the inheritance comes through, they can park it in the offset or make lump sum repayments on the variable portion without break costs.
The decision isn't about predicting rate movements. It's about whether you value certainty in your repayments, whether you're likely to make large additional payments, and whether you'll use an offset account effectively.
Offset Accounts and Redraw: The Difference in Access and Tax Treatment
A mortgage offset account is a transaction account linked to your home loan. The balance in the offset reduces the interest charged on your loan without actually paying down the principal. If you have a $400,000 loan and $30,000 sitting in a linked offset, you only pay interest on $370,000.
Redraw lets you access extra repayments you've already made on the loan. Both reduce interest, but offset gives you cleaner separation of funds and doesn't alter your loan balance. If you're buying your next home while keeping your current property as an investment, offset accounts become particularly valuable because they let you build equity in your owner-occupied loan without muddying the deductibility of interest on your investment property. Pulling money out via redraw on an investment loan can create tax complications that offset accounts avoid entirely.
Most variable rate home loan products include offset as standard. Fixed rate products rarely do.

Interest Only vs Principal and Interest: The Repayment Structure That Affects Cash Flow
Principal and interest repayments reduce your loan balance each month and build equity over time. Interest only repayments cover just the interest charged, leaving your loan balance unchanged. Your monthly repayment on an interest only loan is lower, but you're not reducing what you owe.
Interest only is common for investment loans because it maximises tax deductions and frees up cash flow for other purposes. For an owner occupied home loan, it's less common but can make sense in specific situations. If you're buying in Greater Brisbane while renovating your current home to sell, an interest only period on your new loan keeps repayments lower until the sale settles and you can pay down the debt in one lump sum.
Most lenders allow interest only periods of one to five years on owner-occupied loans, after which the loan reverts to principal and interest. Your repayments jump significantly when that happens because you're now paying off the principal over the remaining loan term. On a $500,000 loan, switching from interest only to principal and interest after five years can increase your monthly repayment by $1,500 to $2,000 depending on the rate.
Loan Features That Match How You'll Actually Use the Property
Portability lets you move your loan to a different property without refinancing. If you're buying in Sunshine Coast and think you might relocate again within a few years, a portable loan saves you discharge fees, application fees, and the time involved in a full refinance. Not all lenders offer it, and those that do often have conditions around loan amount and property type.
Rate discounts vary by lender and loan amount. A loan package with a larger discount off the lender's standard variable rate isn't always better value if the standard rate itself is higher. When comparing home loan rates, focus on the actual interest rate you'll pay, not the size of the discount being advertised.
Additional repayment options matter if you expect irregular income or plan to pay down debt faster. Most variable home loan products allow unlimited extras, but some lenders cap it or charge fees for payments above a certain amount. Fixed rate products almost always restrict additional repayments.
Pre-Approval: Locking in Your Borrowing Capacity Before You Buy
A home loan pre-approval confirms how much you can borrow and at what rate before you start looking at properties. It's conditional, meaning the lender has assessed your income, expenses, and credit history but hasn't valued the property yet.
Pre-approval gives you a clear budget and shows sellers you're a serious buyer. In Queensland markets where stock moves quickly, having pre-approval in place before you attend inspections can be the difference between securing the property and missing out. Most lenders issue pre-approval within a few days and it remains valid for three to six months, depending on the lender.
If your situation changes during the pre-approval period, such as a job change, additional debt, or a drop in income, you'll need to update the lender before proceeding. Pre-approval isn't a guarantee, but it's as close as you'll get without a signed contract.
How Lenders Mortgage Insurance Affects Your Loan Amount and Structure
Lenders Mortgage Insurance (LMI) is a one-off cost charged when you borrow more than 80% of the property's value. It protects the lender, not you, and can add thousands to your upfront costs or loan balance. On a $500,000 property with a 10% deposit, LMI might be $10,000 to $15,000 depending on the lender and your loan to value ratio.
Some lenders offer LMI waivers for professionals in specific industries, which can save you a significant amount if you qualify. Others let you capitalise the LMI into your loan rather than paying it upfront, which increases your borrowing but keeps your cash free for other settlement costs.
If you're close to an 80% LVR, it's worth running the numbers both ways. A slightly larger deposit that avoids LMI entirely might leave you better positioned than stretching to borrow the maximum and wearing the insurance cost.

Frequently Asked Questions
Should I choose a fixed or variable rate for my next home purchase?
A variable rate gives you full offset access and unlimited extra repayments, while a fixed interest rate locks in your rate but restricts flexibility. A split loan can give you both certainty and flexibility if you expect to make large repayments or want to use an offset account while maintaining some rate protection.
What's the difference between an offset account and redraw on a home loan?
An offset account is a linked transaction account where your balance reduces the interest charged on your loan without changing the principal. Redraw lets you access extra repayments you've made, but it alters your loan balance and can complicate tax deductions if you have investment properties.
Do I need home loan pre-approval before looking at properties in Queensland?
Pre-approval confirms your borrowing capacity and shows sellers you're a serious buyer. In Queensland markets where properties move quickly, having pre-approval can make the difference between securing a property and missing out, and it typically remains valid for three to six months.
When does an interest only loan make sense for an owner-occupied property?
Interest only can work for owner-occupied properties when you need lower repayments temporarily, such as when renovating another property to sell or expecting a lump sum payment soon. Your repayments increase significantly when the interest only period ends, so it suits specific short-term situations rather than long-term ownership.
How much does Lenders Mortgage Insurance cost and can I avoid it?
LMI is charged when you borrow more than 80% of the property value and can range from several thousand to tens of thousands depending on your deposit size and loan amount. Some lenders offer LMI waivers for certain professionals, and you can avoid it entirely by providing at least a 20% deposit.
