Unlock the secrets to purchasing your next home

You've built equity in your current place, your income has grown, and you're ready to move into something that suits your family or investment goals.

The lending approach that worked for your first purchase won't deliver the same result now. Lenders assess your borrowing capacity differently when you already hold property, especially if you plan to retain your current home as an investment. The structure you choose, the deposit you access, and the way you present your income all shift the amount you can borrow and the rate you'll pay.

What Changes When You Already Own Property

Your existing mortgage becomes a liability in the serviceability assessment, even if tenants cover most of the repayments. Lenders apply a rental income buffer, typically discounting rental income by 20 per cent to account for vacancy and maintenance costs. If your current property carries a variable rate and you're borrowing for an owner-occupied purchase, the new loan will also be assessed at the current variable rate plus the 3.0 percentage point serviceability buffer mandated by APRA.

Consider an ambulance officer holding a property with $450,000 remaining on the loan and rental income of $2,600 per month. The lender will credit $2,080 per month in rental income after applying the buffer, but the existing loan repayments are assessed at a rate well above the actual rate being paid. The gap between credited income and assessed liability reduces the borrowing capacity available for the next purchase. For officers earning shift allowances, penalty rates, or overtime, getting loan pre-approval with full income documentation before you start looking gives you a precise budget to work within.

Using Equity Without Selling

The equity in your current property can fund the deposit for your next home without requiring a cash injection. Lenders will assess the combined loan-to-value ratio across both properties. If your current home is valued at $650,000 with $450,000 owing, you hold $200,000 in equity. Accessing $130,000 of that equity through a refinance or top-up brings your LVR on the existing property to 89 per cent, which typically triggers LMI unless an LMI waiver applies to your occupation.

For ambulance officers, occupation-specific waivers can allow borrowing up to 90 or even 95 per cent LVR on owner-occupied property without paying LMI. If you're purchasing your next home to live in and keeping the current property as an investment, the waiver applies to the new owner-occupied loan. If you're purchasing an investment property and keeping your current home as your residence, standard LMI rules apply unless the lender offers a waiver on investment lending for your occupation, which is less common. Structuring this correctly means knowing which property will be flagged as owner-occupied before you apply.

In a scenario where an officer is moving from a unit in the outer suburbs into a house closer to their station, they might access $520,000 in new lending at 90 per cent LVR for a $580,000 purchase, using $52,000 from equity and $8,000 in cash for the balance of the deposit and costs. The existing property is converted to an investment loan, rental income is added to the application, and the combined structure is assessed as a single borrowing position. The outcome depends on how the lender applies rental income shading, how they treat shift penalties, and whether the new loan qualifies for a rate discount through an offset or professional package.

Owner-Occupied or Investment: Which Loan Goes Where

The property you occupy as your residence must be funded with an owner-occupied loan. The property you rent out must be on an investment loan. Lenders verify occupancy through rates notices, lease agreements, and declarations at settlement. If you move into the new property, your existing loan must be converted to an investment rate, which is typically 0.30 to 0.60 percentage points higher than the equivalent owner-occupied rate.

This conversion is not automatic. You need to notify your lender in writing and provide evidence of the change in occupancy. If you delay the conversion and the lender discovers the occupancy change during a portfolio review or audit, they may backdate the investment rate and apply penalty interest. Keeping your loan structure aligned with your actual occupancy protects you from compliance issues and ensures you're claiming the correct tax deductions on the investment property.

Split Rate Structures Across Two Properties

When you hold two loans, a split rate structure on either or both properties can reduce interest cost and manage repayment risk. On the investment loan, fixing a portion of the balance locks in deductible interest at a known rate while keeping a variable portion with an offset account to manage tax-deductible debt and non-deductible savings separately. On the owner-occupied loan, splitting allows you to fix part of the repayment while maintaining offset access on the variable portion.

An officer refinancing an existing $450,000 investment loan and taking out a new $520,000 owner-occupied loan might fix $300,000 of the investment balance for three years and leave $150,000 variable with no offset, then fix $350,000 of the owner-occupied balance and leave $170,000 variable with a linked offset holding emergency savings and offset contributions. The fixed portions provide repayment certainty, and the variable portions with offset deliver flexibility and tax efficiency. The structure can be adjusted at each fixed rate expiry, and our fixed rate expiry support includes reviewing your position and recommending a new structure before the fixed term ends.

Borrowing Capacity When Rental Income Is Involved

Lenders calculate your borrowing capacity by taking your gross income, adding 80 per cent of gross rental income, then subtracting all ongoing liabilities including the new loan assessed at the serviceability buffer rate, existing loans assessed at the same buffer, and minimum repayments on credit cards and personal loans. The difference between lenders can be significant. Some lenders apply a higher rental income buffer or assess shift allowances more conservatively, reducing your borrowing capacity by $50,000 to $100,000 compared to a lender that fully recognises your income structure.

For officers working across NSW Ambulance, Queensland Ambulance Service, or Ambulance Victoria, penalty rates, shift allowances, and overtime are structural parts of your income, not bonuses. Presenting this income with payslips covering a full roster cycle and a letter from your employer confirming the permanence of the allowances ensures the lender includes the maximum amount in the assessment. Officers moving into specialist or management roles should also confirm whether any reduction in shift work will affect the income used in the application.

When to Sell Instead of Hold

Holding your current property as an investment only works if the rental income and capital growth justify the reduction in borrowing capacity and the ongoing cost of holding two loans. If the rental yield is below 4 per cent, the interest cost exceeds the rental income, and you're funding the shortfall from your salary while also servicing the new loan. That structure can work if you expect strong capital growth or if negative gearing benefits offset the cash flow gap, but it reduces your financial flexibility and limits your ability to borrow further in the short term.

Selling the current property before purchasing the next one removes the existing liability from your serviceability assessment and releases the full equity as cash. You'll pay capital gains tax on any gain above the cost base if the property was rented out after you moved out, and selling costs including agent fees and marketing will reduce your net proceeds by 2 to 3 per cent of the sale price. If the equity released and the improved borrowing capacity allow you to purchase a home that would otherwise be out of reach, selling is often the clearer path forward. If you can hold both properties comfortably and the investment property supports your long-term wealth strategy, retention makes sense. The decision comes down to cash flow, borrowing capacity, and your goals for the next five years, not just the next purchase.

Bridging Finance for Overlapping Settlements

If you're selling your current home and purchasing the next one, and the settlement dates don't align, bridging loans cover the gap. The bridging loan allows you to settle on the new property using the equity in the existing property before the sale completes. Interest is typically charged on the bridging loan at a higher rate than a standard variable loan, and the term is usually three to six months.

Bridging finance is structured as end debt and peak debt. Peak debt is the combined total of your existing loan and the new loan during the bridging period. End debt is the amount you'll owe after the existing property is sold and the proceeds are used to pay down the combined borrowing. Lenders assess your capacity to service the peak debt, so if the bridging period extends or the sale falls through, you need to demonstrate that you can continue to service both loans. Officers using bridging finance should have a signed sale contract with an unconditional status before settlement on the purchase, and a buffer to cover bridging interest and any holding costs if the sale is delayed.
