Unlock the secrets to upsizing your home on shift work

Your family has outgrown the current place and you need more bedrooms, a proper backyard, maybe space for a home office where you can decompress after a night shift.

The difference between upsizing successfully and stretching yourself too thin comes down to three things: how much equity you can pull from your current property, whether your borrowing capacity covers the gap, and how the loan structure holds up when you're rostered on nights for three months straight.

How much equity can you actually use to upsize?

You can typically borrow up to 80 per cent of your current home's value without paying LMI, meaning the equity you can access is your property's current value minus what you still owe, minus the 20 per cent buffer the lender holds back. Consider someone who bought at $650,000 three years ago with a 10 per cent deposit and now owes $560,000. If the property is now worth $750,000, they have $190,000 in equity on paper, but the usable amount without triggering LMI is $600,000 minus $560,000, which leaves $40,000. That amount needs to cover part of the new deposit, stamp duty, conveyancing, and any settlement costs on the larger property. In some cases it's enough. In others, you'll need genuine savings to close the gap or accept that LMI becomes part of the transaction.

Some lenders offer LMI waivers for law enforcement officers at LVRs up to 90 or even 95 per cent, which can change the calculation entirely. That same borrower could access $675,000 minus $560,000, leaving $115,000 in usable equity without paying the insurance premium. It's worth checking whether your occupation qualifies before you lock in a purchase price.

Calculating your new borrowing capacity with shift penalties

Borrowing capacity is calculated on your base salary plus any allowances or overtime the lender will accept at full value or a discounted percentage. Most major lenders will take 80 to 100 per cent of regular shift penalties for police officers, but you need payslips that show consistency over at least three months, ideally six. If your overtime varies week to week, some lenders average it and apply a discount. Others won't count it at all. The difference in how one lender treats your penalty rates versus another can shift your borrowing capacity by $80,000 or more, which is often the difference between affording the four-bedroom house you need and being stuck at three.

When you're upsizing, your total debt includes both the new loan and any portion of the old loan that remains if you're holding both properties during settlement. Even if you're selling, some lenders assess you as though you're carrying both until the sale completes. That temporarily lowers what you can borrow. If the sale falls through or settles late, you need enough capacity to service both loans or a bridging loan structure that covers the gap without exceeding your limit. Your broker should run the numbers assuming worst case, not ideal case.

Should you sell first or buy first when upsizing?

Selling first gives you certainty on price and removes the risk of holding two mortgages, but it also means you might need temporary accommodation and you're shopping for the new place without knowing exactly when settlement will happen. Buying first lets you secure the right property without rushing, but you're exposed to bridging finance costs and the risk that your current home takes longer to sell than expected. For law enforcement officers, the decision often comes down to whether you can get loan pre-approval that includes your usable equity and whether the lender will service you on both loans for a short period.

In our experience, officers with stable rosters and strong penalty rate income tend to have enough capacity to bridge for 60 to 90 days if needed. Those on variable hours or carrying other debt usually need to sell first. There's no universal right answer, but the wrong choice locks you into a timeline that doesn't suit your circumstances.

Fixed, variable or split when you're upsizing

Variable rates give you flexibility to make extra repayments and pay down the loan faster, which matters when you've just increased your debt by $200,000 or more. Fixed rates lock in your repayment amount, which can help with budgeting if your household income fluctuates or if you want certainty through the first few years of a larger mortgage. A split loan gives you both: a portion fixed for stability, a portion variable for flexibility. Most officers we work with split 50-50 or 60-40 in favour of variable, depending on their risk tolerance and how aggressively they want to reduce the principal.

The structure you choose should match how you'll actually use the loan. If you're planning to renovate the new place in two years, you want variable or a split with enough variable room to redraw. If you're stretched on repayments and need predictable costs, a higher fixed portion makes sense even if it limits your options later.

Offset accounts and why they matter more when upsizing

An offset account linked to your home loan reduces the interest you pay by offsetting your savings balance against the loan principal. When you upsize, your loan amount increases and so does the interest benefit of every dollar sitting in offset. If you're holding $30,000 in offset against a $400,000 loan, you're saving interest on that $30,000. If you're holding the same $30,000 against a $650,000 loan at current variable rates, the annual saving is the same per dollar, but the proportional impact on your minimum repayment and total interest over time compounds faster on the larger debt.

Offset works well for officers who receive annual leave payouts, overtime lumps, or shift penalty accumulation that sits in the account between pay cycles. You're not locking the cash away, so it's still accessible for emergencies or planned expenses, but while it's there it's reducing your interest. Some lenders charge a monthly fee for offset. Others include it at no cost. The fee is irrelevant if the interest saving exceeds it, which it almost always does once your offset balance exceeds $10,000.

LMI waivers and how they apply to upsizing purchases

LMI waivers are available through select lenders for law enforcement officers purchasing at LVRs above 80 per cent without paying the insurance premium. When you're upsizing, this can mean the difference between needing $120,000 in usable equity and needing $60,000, because you're borrowing a higher percentage of the new property's value without penalty. Not all lenders offer the waiver, and those that do cap it at different LVR thresholds depending on your occupation, employment type, and income level.

If you're buying a home at the current median in your target suburb and your equity from the sale only covers part of the deposit, an LMI waiver lets you proceed without either waiting to save the shortfall or paying a premium that could be $15,000 to $25,000 depending on loan size. The waiver doesn't change your borrowing capacity, but it does change how much cash you need at settlement, which in turn affects whether the upsize is possible now or in two years.

Stamp duty and settlement costs you need to budget for

Stamp duty varies by state and by property value, and when you're upsizing from a $600,000 property to a $900,000 property, the duty bill can increase by $30,000 or more depending on where you're buying. In New South Wales, duty on a $900,000 established home is roughly $34,000. In Victoria it's closer to $48,000. That's on top of conveyancing, building and pest inspections, loan application fees, and any settlement adjustments for council rates or water. Budget at least 5 per cent of the purchase price for all costs combined, more if you're in Victoria or purchasing in a high-value bracket.

If your usable equity doesn't cover the full deposit and costs, you'll need genuine savings or family assistance to close the gap. Some lenders allow you to capitalise LMI into the loan if you don't have a waiver, but that increases your loan amount and your ongoing repayments. Know the full cost before you make an offer, not after.

When a guarantor loan makes sense for upsizing

A guarantor loan allows a family member, usually a parent, to use equity in their own property as security for part of your deposit, which lets you borrow more without paying LMI. This can work when you're upsizing and your equity from the current property doesn't quite get you there. The guarantor isn't giving you money, they're providing security, and their portion of the guarantee can be released once you've paid down enough principal to reach 80 per cent LVR on your own.

The risk is that if you default, the lender can pursue the guarantor's property. That makes it a serious commitment and one that needs independent legal advice for the guarantor before anyone signs. It's not a fallback for affordability problems, it's a tool to bridge a temporary equity gap when your income can service the full loan.
