Beginner's Guide to Upgrading Your Family Home

Can You Upgrade Your Home While You're Still Paying Off Your First Loan?

You can upgrade to a bigger home before paying off your existing mortgage. Most buyers keep their current loan running and either sell their first property to access equity for the next deposit, or release equity while keeping the original home as an investment.

The decision usually comes down to whether you can access enough funds for a deposit on the next property without selling. If you bought your first home a few years ago and the property has increased in value, you may have built up usable equity even if you haven't paid down much of the principal. Lenders typically allow you to borrow up to 80% of your current home's value without paying Lenders Mortgage Insurance. Anything above that usually requires LMI, which adds to your costs.

Consider someone who purchased in Mount Waverley three years ago. They paid a 5% deposit using the Australian Government 5% Deposit Scheme and still owe close to the original loan amount. If the property has increased in value by 15% over that time, they now have equity they can potentially access. A broker can arrange a valuation to confirm the current value, then calculate how much can be released toward the next purchase. The borrower would need to demonstrate they can service both loans if keeping the original property, or show they can afford the new loan if selling.

This is where many people start looking at upgrading your house properly, rather than guessing what might be possible.

Should You Sell First or Buy First?

Selling first gives you certainty around your deposit and borrowing capacity, but it often means moving twice or renting temporarily. Buying first lets you move once and avoid rental costs, but requires approval for bridging finance or enough equity to fund both properties until settlement.

If you're planning to keep your first home as an investment, you'll need to demonstrate serviceability for both loans at the same time. Lenders assess whether your income can cover both repayments, plus living expenses, using a buffer rate above the actual interest rate. If you're selling, the lender will usually allow you to borrow based on your income alone, provided the sale contract shows settlement will occur before or at the same time as your purchase.

Bridging finance is a short-term loan that covers the gap between buying your next home and selling your current one. It's secured against your existing property and typically lasts three to six months, though some lenders offer up to twelve months. Interest is usually capitalised, meaning it's added to the loan balance rather than paid monthly. The total borrowing across both properties can't exceed the lender's maximum loan-to-value ratio, and you'll need a signed sale contract or active marketing evidence to show the property is genuinely being sold.

If you're using a bridging loan to upgrade, expect the lender to assess both properties and require proof the existing home is listed or under contract.

How Do Lenders Assess Your Borrowing Capacity When Upgrading?

Lenders calculate how much you can borrow by taking your income, subtracting your living expenses and existing debts, then applying a buffer to the interest rate. If you're keeping your first home as an investment, rental income can be included but is usually discounted by 20% to 30% to account for vacancy and maintenance.

Your borrowing capacity will be lower than it was when you bought your first home if you're servicing two loans. This is why selling often makes sense for buyers who need to maximise what they can borrow for the upgrade. If your income has increased since the first purchase, or you've paid off other debts like car loans or credit cards, that may offset the impact of holding two mortgages.

Someone earning $95,000 a year with a partner earning $80,000 might have qualified for a loan of around $650,000 when they bought their first home. If they now want to upgrade and keep the original property, the lender will assess rental income against the existing mortgage and reduce their available borrowing capacity accordingly. If the rental income doesn't fully cover the mortgage, the shortfall is deducted from their income before calculating what they can borrow for the new property. Selling the first home removes that limitation and often restores their full borrowing capacity, assuming their income and expenses have remained stable.

What Deposit Do You Need to Upgrade?

Most lenders require a 20% deposit to avoid paying LMI on an upgrade purchase. If you're releasing equity from your existing home, the usable amount is typically the difference between 80% of the property's current value and what you still owe on the loan.

If your current home is valued at $750,000 and you owe $600,000, you can usually borrow up to 80% of the value, which is $600,000. Since you already owe that amount, there's no equity available to release without paying LMI. If the same property is valued at $850,000 and you owe $600,000, you can borrow up to $680,000. That leaves $80,000 in usable equity, minus any refinancing costs.

Releasing equity works differently depending on whether you're keeping the original property or selling it. If selling, the deposit comes from your sale proceeds after the existing loan is paid out. If keeping it, you're refinancing to pull equity out, which increases the loan balance on that property. You'll need to factor in the higher repayment when lenders assess your serviceability for the new loan.

Can You Use the 5% Deposit Scheme Again When Upgrading?

The Australian Government 5% Deposit Scheme is available only to first home buyers who have not previously owned property in Australia. If you used the scheme to buy your first home, you're not eligible to use it again when upgrading.

If you didn't use a government scheme the first time and still meet the first home buyer definition in your state or territory, you may be eligible depending on when you last owned property. Each state defines a first home buyer differently for stamp duty purposes, but the federal scheme applies a national rule: if you or your spouse or de facto partner currently own or have previously owned property in Australia, you're not eligible. That includes investment properties, inherited properties, and properties owned before your current relationship.

Buyers upgrading from a first home are typically working with equity from the sale or releasing equity to purchase using a standard refinance or top-up loan.

How Does Upgrading Affect Your Interest Rate and Loan Features?

When you upgrade, you're applying for a new loan on the new property. That loan will be assessed at current interest rates, which may be higher or lower than the rate on your existing mortgage. If you're keeping your first property, you can choose to refinance that loan at the same time to access a lower rate or better features.

Most owner-occupied variable rate loans come with an offset account, redraw facility, and the ability to make extra repayments without penalty. If you're converting your first home to an investment property, you may need to switch the loan to an investment rate, which is often slightly higher than an owner-occupied rate. Some lenders allow you to keep the same loan and simply notify them of the change in occupancy, while others require a formal refinance.

If you're selling your first home, the loan on that property will be discharged at settlement. Any break costs from exiting a fixed rate early, or discharge fees, will be deducted from your sale proceeds. The new loan will have its own rate, terms, and features based on what's available at the time of application.

Comparing your options across multiple lenders is part of the standard process when upgrading. A broker has access to loan products from a wide panel and can show you how different rate types and features affect your repayments and flexibility over time.

What Happens to Stamp Duty and Other Costs When Upgrading?

You'll pay stamp duty on the purchase price of your new home unless you're eligible for a concession in your state. In Victoria, stamp duty for owner-occupiers who are not first home buyers is calculated on the full purchase price with no general concession. If you're buying in Melbourne's middle or outer suburbs, expect stamp duty to add tens of thousands to your upfront costs.

Other costs include conveyancing, building and pest inspections, loan application fees, and valuation fees. If you're selling at the same time, agent fees and marketing costs will be deducted from your proceeds. If you're using bridging finance, there's usually a higher interest rate during the bridging period and additional fees for setting up and discharging the short-term facility.

Budgeting for these costs early avoids surprises at settlement. Most buyers underestimate how much stamp duty will add to the total outlay, particularly when moving from a lower-priced first home to a property in a higher price bracket.

How Long Does the Upgrade Process Usually Take?

The timeline depends on whether you're selling first, buying first, or doing both simultaneously. If you're selling before you buy, expect three to six months from listing your property to settling on the new one. If you're buying first with bridging finance, the process is faster but requires pre-approval and a clear understanding of how much you can borrow across both properties.

Pre-approval is helpful but not always essential if you're selling first and waiting for settlement proceeds. If you're using equity or bridging finance, pre-approval gives you confidence around your budget before you start looking. Most lenders issue pre-approval within a few days to a week, provided your documents are complete and your financial position is straightforward.

Once you've found a property and made an offer, formal approval takes one to three weeks depending on the lender and how quickly valuations and other checks are completed. If you're coordinating settlement on a sale and purchase at the same time, your conveyancer will work with both sides to align the dates.
