Understanding Your Borrowing Position When Upgrading
Your borrowing capacity when upgrading depends on whether you keep or sell your current property. If you sell before buying, lenders assess your income against the new loan amount without the complication of existing debt. If you keep the property as an investment, lenders factor in rental income but also apply serviceability buffers that reduce how much you can borrow.
Consider a buyer who owns a two-bedroom unit in Ashburton and wants to move to a four-bedroom home in Glen Iris. If they sell the unit and use the equity as a deposit, they might borrow based on 80% of the purchase price, avoiding Lenders Mortgage Insurance. If they convert the unit to an investment property instead, the lender will assess rental income at around 80% of the actual rental return and test the loan against a higher interest rate buffer. In this scenario, the buyer's borrowing capacity dropped by roughly $150,000, which changed the type of property they could target.
When upgrading in Glen Iris, where properties near Gardiner Station or along High Street command higher prices than surrounding suburbs, understanding your serviceability position before you start looking prevents disappointment later. A home loan pre-approval gives you a clear borrowing limit and shows sellers you can settle quickly.
Selling First or Buying First
Selling your current home before purchasing the next one removes financing uncertainty but creates the risk of temporary accommodation or settling twice. Buying first secures the property you want but requires bridging finance or sufficient equity to fund both deposits simultaneously.
Bridging finance allows you to purchase the new property before settling the sale of your existing home. Lenders provide short-term funding based on the expected sale price of your current property, typically for six to twelve months. Interest accrues daily and capitalises monthly, so timing the sale becomes important to limit costs. Most lenders require at least 20% equity across both properties to approve bridging loans, and some will not lend if your current property is already listed without a contract.
In Glen Iris, where auction clearance rates and days on market fluctuate depending on proximity to schools like Glen Iris Primary or Malvern Central School, the decision between selling first and buying first often comes down to how confident you are in selling within a defined period. If your current property is in a high-demand pocket and priced correctly, bridging finance may be appropriate. If the market is softer or your property has features that narrow the buyer pool, selling first reduces risk.

Using Equity From Your Current Property
Equity is the difference between your property's current value and what you owe on the loan. Most lenders allow you to borrow against up to 80% of your property's value without paying Lenders Mortgage Insurance. If you own a property valued at $900,000 with a loan balance of $500,000, you have $400,000 in equity, and you can access up to $220,000 of that without incurring LMI.
This equity can fund the deposit on your next home, cover stamp duty, and pay for conveyancing and other settlement costs. In suburbs like Glen Iris, where established homes on larger blocks are tightly held, having access to equity means you can move quickly when the right property becomes available, particularly at auction.
If your equity position is below 80%, you may still be able to upgrade by paying LMI or using a guarantor. Some lenders offer low LMI loans with reduced premiums for borrowers with strong serviceability, which can make upgrading viable even when your deposit is below the standard threshold.
Structuring the Loan on Your New Home
The loan structure you choose affects flexibility, repayment speed, and interest costs over time. Most buyers upgrading to a larger family home use a variable rate with an offset account, which allows them to reduce interest while keeping funds accessible for school fees, renovations, or future investment opportunities.
A split loan combines a fixed rate portion for repayment certainty and a variable rate portion for flexibility. This structure works well when interest rates are volatile or when you want to lock in part of your repayment while maintaining the option to make extra payments on the variable portion. The fixed rate percentage you choose should reflect how much repayment stability you need rather than a guess about future rate movements.
In our experience, families upgrading in Glen Iris often prefer offset accounts linked to their variable rate loan because it allows them to park savings, bonuses, and rental income in the offset and reduce interest without locking funds into the loan. If you later decide to purchase an investment property or renovate, those funds remain available without needing to redraw or reapply.
Loan Features That Support Long-Term Plans
When comparing home loan options, look beyond the interest rate to features that align with your plans over the next five to ten years. Portability allows you to transfer the loan to a different property without refinancing, which is useful if you upgrade again or purchase an investment property. Redraw facilities let you access extra repayments if needed, though some lenders place conditions on how much you can withdraw and how often.
Offset accounts provide the most flexibility because funds remain separate from the loan and are fully accessible at any time. The balance in the offset is deducted from your loan balance when calculating interest, which means a $50,000 offset balance on a $700,000 loan reduces interest as if you owe $650,000. Not all lenders offer 100% linked offset accounts, so confirm the structure before proceeding.
If you plan to retain your current property as an investment after upgrading, ensure the new loan structure keeps your owner-occupied and investment debts separate. This separation is important for tax purposes and makes future refinancing or equity release simpler. Speak to your accountant before finalising any structure that involves converting your home into an investment property.
Timing Your Application and Settlement
Lenders assess your financial position at the time of application and again just before settlement. If your income, employment, or debts change between approval and settlement, the lender may reassess or withdraw the offer. Avoid taking on new credit, changing jobs, or making large purchases during this period.
Pre-approval is typically valid for three to six months, depending on the lender. In Glen Iris, where properties close to Toorak Road or the Anniversary Trail can move quickly, having home loan pre-approval in place before attending auctions or making private offers puts you in a stronger negotiating position. Sellers and agents recognise the difference between a buyer with conditional approval and one who has already satisfied most lending conditions.
Settlement periods in Victoria are commonly 60 to 90 days, though this can be negotiated. If you are using bridging finance, a longer settlement period on your purchase gives you more time to sell your existing property and reduces the period where you are paying interest on both loans.
When to Involve a Mortgage Broker
Upgrading your family home involves more variables than a standard purchase. A mortgage broker can model different scenarios based on whether you sell or hold your current property, compare loan structures across lenders, and identify features that suit your specific situation. We regularly see borrowers who assume they need to sell first, only to find that their equity position and rental income support buying first with the right loan structure.
Brokers also have access to loan products not available directly to consumers, including low LMI loans and portfolio lending options that assess multiple properties together rather than individually. For buyers upgrading in Glen Iris, where property values and borrowing amounts are higher than many other Melbourne suburbs, the difference in interest rates and loan features can amount to tens of thousands over the life of the loan.
Call one of our team or book an appointment at a time that works for you. We will assess your current position, model your borrowing capacity under different scenarios, and structure a loan that supports both your immediate upgrade and your longer-term financial plans.
Frequently Asked Questions
Can I borrow enough to upgrade if I keep my current property as an investment?
Your borrowing capacity will be lower if you keep your current property because lenders assess rental income at around 80% of the actual return and apply serviceability buffers. A mortgage broker can model both scenarios to show how much you can borrow under each option.
What is bridging finance and when should I use it?
Bridging finance is short-term funding that allows you to purchase a new property before selling your existing home. It is appropriate when you have at least 20% equity across both properties and are confident you can sell within six to twelve months.
How much equity can I access from my current property?
Most lenders allow you to borrow up to 80% of your property's value without paying Lenders Mortgage Insurance. The difference between 80% of the value and your current loan balance is the equity you can access for your next purchase.
Should I choose a variable or fixed rate when upgrading?
Variable rates with offset accounts provide flexibility for extra repayments and accessible savings. A split loan can offer repayment certainty on part of the loan while keeping flexibility on the remainder, depending on your priorities.
Do I need a mortgage broker to upgrade my family home?
A broker can model different scenarios, compare loan structures across lenders, and identify features that suit your specific situation. Upgrading involves more variables than a standard purchase, and professional advice can save time and money.
