What Are Your Options When Upgrading Your Grange Home?

Upgrading your family home in Grange means solving an equity and capacity problem simultaneously.

The current house median in Grange sits at $1,877,500, and with rental vacancy across Brisbane City at 0.5%, buyers looking to upsize are moving from one supply-constrained market into another. The question isn't whether you have enough equity to make the move, it's whether your borrowing capacity can support the purchase price without forcing the sale of your current property first. Many families who bought in surrounding suburbs including Alderley or Newmarket are now looking to move into Grange, Wilston, or Ashgrove where the median house price sits between $1.6m and $2m. The borrowing structure you choose determines whether you can move before you sell, whether you can hold both properties temporarily, and whether you absorb break costs or refinance around them.

Can you buy before you sell?

This depends on whether the lender will assess your current home as an investment property or ignore its income entirely during the application. Consider a buyer who owns a home in Kedron at the suburb's median of $1,590,000 with a remaining loan balance of $600,000. Usable equity sits at approximately $672,000 after allowing for an 80% loan-to-value ratio and holding back funds for costs. That buyer wants to purchase in Grange at $1,900,000. A 10% deposit requires $190,000, leaving roughly $480,000 in residual equity. The challenge is serviceability. If the buyer intends to sell the Kedron property after settlement, most lenders will assess the new loan without rental income from the existing home, meaning the application is tested against a single household income servicing two mortgages temporarily. That structure works when income is high relative to debt, but fails when the buyer is already at or near their debt-to-income limit.

If the buyer instead declares the Kedron property as an investment property, the lender will include rental income in the assessment, but will also apply a higher interest rate to the retained loan and assess the new Grange purchase as owner-occupied. Rental income is typically shaded by 20% to account for vacancy and costs, so a property renting at $775 per week contributes roughly $620 per week to serviceability. Whether this structure improves the outcome depends on the size of the retained loan, the rental yield, and the rate differential between owner-occupied and investment lending on your existing facility.

Fixed rate break costs and timing your purchase

If your current home loan is on a fixed rate and you're within the fixed term, breaking the loan to access equity or increase the borrowing limit will trigger break costs. These are calculated based on the difference between your fixed rate and the wholesale rate the lender can now earn on the money for the remaining term. In a rising rate environment, break costs are typically minimal or nil. In a falling or flat rate environment, they can run into the tens of thousands.

Rather than breaking the fixed loan, some buyers choose to leave the existing loan untouched and apply for a standalone loan for the deposit and costs using undrawn equity as security. This approach works where the buyer has sufficient unencumbered equity in the existing property and does not need to refinance or increase the current facility. The new loan is written as a separate split, often at a variable rate, and can be structured as interest-only during the holding period if the existing home will be sold within six to twelve months. The risk is that you are now servicing two loans on two properties, and if the sale of the original home is delayed, you may not meet the lender's requirements to consolidate or discharge the interim facility on time.

Split rate structures when holding two properties temporarily

When buyers hold two properties during a transition period, whether by choice or necessity, the loan structure needs to reflect both the short-term cash flow requirements and the longer-term position once the original property is sold. A common structure is to fix the majority of the new loan and hold the balance on a variable rate with an offset account linked to the variable portion. This allows the proceeds from the sale of the original property to sit in offset and reduce interest immediately without triggering break costs or early repayment penalties.

Consider a buyer purchasing in Grange at $1,900,000 with a loan of $1,520,000 after using available equity for the deposit. That buyer might fix $1,200,000 at current fixed rates for three years and leave $320,000 on a variable rate linked to a full offset account. Once the Kedron property settles and the buyer receives net proceeds of $1,000,000 after discharge and costs, those funds sit in the offset account and eliminate interest on the variable portion entirely while leaving the buyer the flexibility to either redraw for renovations or apply the funds to reduce the fixed portion at the next break point without penalty. The fixed portion provides rate certainty on the bulk of the debt, and the variable portion provides liquidity and control.

Portable loans and taking your rate with you

Some lenders offer portability, meaning you can transfer your existing loan and interest rate to a new property without breaking the contract or reapplying. This feature is valuable when you are mid-way through a fixed term on a rate that is lower than the current market, or when you want to avoid a full credit assessment and valuation process on the new property. Portability is not universal across all loan products. Most lenders will allow you to increase the loan balance when porting, but the additional borrowing will be priced at current rates, not the legacy rate you are transferring.

Portability works cleanly when the sale and purchase settle on the same day or within a narrow window. If there is a gap of more than a few weeks, the lender may require you to discharge the original loan and reapply, or to move the loan onto a notional security until the new property settles. Not all lenders support notional security structures, and those that do will typically apply conditions around the maximum period and the loan-to-value ratio on the new property.

Using pre-approval to hold a price and rate

A home loan pre-approval allows you to make an offer with certainty around your borrowing limit and, in some cases, lock in a rate for a period of 90 days. Rate locks are not standard on all pre-approvals, and where they are offered, they typically apply only to fixed rates, not variable rates. A rate lock protects you if rates rise between the date of pre-approval and the date of settlement, but offers no benefit if rates fall, as you remain committed to the locked rate unless you pay a break cost to exit.

Pre-approval is assessed on the same serviceability criteria as a full application, including the debt-to-income limits introduced in February this year. Each lender may approve up to 20% of new owner-occupier loans to borrowers with a total debt-to-income ratio of six times or greater, but most borrowers upgrading from an existing property with a substantial mortgage will fall outside that threshold unless their income has increased materially or they are selling the original property before settlement. In our experience, buyers upgrading in Grange or Wilston are typically trading up from a suburb with a median between $1.4m and $1.7m, meaning they are adding $300,000 to $500,000 in net debt after the sale proceeds are applied. Pre-approval gives you confidence on capacity, but does not eliminate the need to structure the bridging period carefully.

What happens when you can't sell in time

If your original property does not sell before your new purchase settles, you will need to fund the deposit and settlement from savings, a short-term facility, or by holding both properties on a bridged loan structure. Some lenders offer formal bridging finance, which allows you to borrow up to the combined value of both properties at a loan-to-value ratio of 80%, with the understanding that the original property will be sold within a defined period, typically six months. Bridging finance is priced higher than standard variable rates, and the lender will require evidence of the property being actively marketed and priced to sell.

An alternative is to extend settlement on the new property by negotiating a longer settlement period at the contract stage, typically 90 to 120 days, giving you time to sell without requiring a formal bridge. This approach depends on the seller's circumstances and is more common in off-market transactions or where the seller is also buying and needs time to settle their own purchase. In the current Grange market, where stock on market is low and buyer competition remains solid despite softer auction clearance rates across Brisbane, sellers are less willing to offer extended settlements unless the price reflects the delayed access to funds.
