Proven tips to structure your home loan correctly

Loan structure determines how much flexibility you have when conditions change

Your loan structure affects how much interest you pay, how accessible your funds are, and how responsive your loan is to rate movements. A variable rate loan moves with the official cash rate and allows unlimited additional repayments without penalty. A fixed rate loan locks your rate for a defined period, typically one to five years, and limits your ability to make extra repayments above a set threshold without incurring break costs. Principal and interest repayments reduce your loan balance over time, while interest-only repayments hold the balance steady and reduce monthly costs in the short term.

In Brunswick, where buyers are often balancing renovation timelines with tight budgets, selecting the right structure at settlement determines how much room you have to adjust later. Many borrowers choose a split structure to hold partial rate certainty while retaining access to redraw or offset on the variable portion.

Split rate structures reduce exposure without locking in entirely

A split rate loan divides your borrowing between a fixed portion and a variable portion. The fixed portion stabilises a percentage of your repayments, while the variable portion remains flexible for additional repayments or early paydown. Splits are typically expressed as a ratio such as 50/50, 60/40 or 70/30, though any ratio is possible depending on your lender's terms.

Consider a buyer refinancing an older terrace in Brunswick. They owe $520,000 and want to protect half their loan from further rate rises while keeping access to a redraw facility on the remainder. They fix $260,000 at the current fixed rate and leave $260,000 variable with a linked offset account. If rates rise, half their loan is insulated. If they receive a bonus or tax return, they can deposit funds into the offset or pay down the variable portion without penalty.

Offset accounts reduce interest without locking funds away

An offset account is a transaction account linked to your home loan where the balance is offset daily against your loan principal for interest calculation purposes. If you have a $400,000 loan and $30,000 in your offset account, you pay interest on $370,000. The funds in the offset remain accessible at all times and are not considered an early repayment.

Offset accounts are only available on variable rate loans or the variable portion of a split loan. If you maintain a consistent cash buffer for irregular expenses such as rates, insurance or annual memberships, an offset account reduces your interest cost without requiring you to redraw funds later. This is particularly relevant for buyers in Brunswick who may be setting aside funds for council permits, strata levies or staged renovation work on older properties in the area.

Not all lenders offer full 100 per cent offset. Some products offer partial offset where only a percentage of your balance is counted. Confirm the offset structure before committing to a loan product.

Interest-only periods suit investors and buyers coordinating settlement timing

An interest-only period allows you to pay only the interest component of your loan for a defined term, typically one to five years. Your loan balance does not reduce during this period, and your repayments are lower than they would be under principal and interest. Once the interest-only period ends, the loan reverts to principal and interest and is recalculated over the remaining term.

Interest-only loans are used primarily by property investors to maximise tax deductions and manage cash flow across multiple properties. They are also used by owner-occupiers who are selling one property and purchasing another, or coordinating construction timelines where they need to minimise repayments temporarily while holding two loans. Under APS 112, long-term interest-only residential loans with an LVR greater than 80 per cent and a contractual interest-only period exceeding five years are classified as non-standard, attracting higher capital requirements for the lender and typically higher rates or restricted availability for the borrower.

For buyers purchasing an investment property in Brunswick, interest-only can be structured on the variable portion of a split loan. This preserves flexibility while keeping a portion of the loan on principal and interest to build equity over time.

Portable loans allow you to transfer your borrowing to a new property without refinancing

A portable loan is a loan product that permits you to transfer your existing facility, including your current rate and terms, to a new property when you sell and purchase without discharging the original loan. Portability is particularly useful for borrowers on a fixed rate who want to avoid break costs, or for those who want to retain a discounted rate negotiated under previous market conditions.

Not all lenders offer portability, and conditions vary. Some lenders require the new property to settle within a defined period after the sale of the old property, typically 90 to 180 days. Others allow portability only if the new loan amount is equal to or greater than the existing balance. If you are planning to move within Brunswick or to a neighbouring suburb such as Coburg or Northcote within the next few years, confirm portability terms at the time of initial application rather than at the point of sale.

Sequentially ranked loans over the same property are aggregated for LVR calculation

Where multiple loans are secured over the same property in sequential ranking order with no intermediate interest from another lender, APS 112 requires the loan amounts to be aggregated and treated as a single exposure for the purpose of calculating the loan to value ratio. This affects how much you can borrow across multiple facilities without triggering LMI, and how lenders assess risk weighting for capital purposes.

This becomes relevant when structuring debt for buyers who want to separate their borrowing by purpose, such as isolating investment debt from owner-occupied debt for tax purposes, or splitting borrowing across two lenders to access different product features. The sequencing and aggregation rules do not prevent you from structuring your loans this way, but they do affect how each lender calculates serviceability and LVR at the time of application and throughout the life of the loan.

Refinancing to restructure is common once equity builds or circumstances shift

Many borrowers who select a loan structure at purchase later refinance to access equity, consolidate debt, or take advantage of lower rates or better offset terms. Refinancing allows you to change the structure of your borrowing without selling the property.

For example, a buyer who purchased in Brunswick three years ago with a 90 per cent LVR loan and no offset may now have enough equity to refinance to an 80 per cent LVR loan with a full offset account and lower rate. Refinancing also allows you to split a loan that was previously entirely variable, or move from interest-only to principal and interest once cash flow improves. A loan health check every 12 to 24 months helps identify whether your current structure still matches your financial position and goals.
