Do you know when to upsize for your growing family?

When Your Current Home No Longer Fits

Many dental technicians reach a point where their current property doesn't accommodate a growing family, but worry about whether their income will support a larger loan. The answer depends less on your total earnings and more on how lenders assess your employment structure and existing commitments.

As a dental technician, your income may include a base salary plus overtime or shift allowances, or you might operate through a laboratory with variable billing patterns. Lenders familiar with the dental industry understand these structures and can assess your borrowing capacity using consistent earnings rather than requiring every dollar to appear as base salary. This matters when you're moving from a smaller mortgage to a significantly larger one.

Consider a dental technician working in a private laboratory in Sydney's inner west, earning a combination of salary and regular overtime. Their current property, a two-bedroom unit, no longer works with two children and a third expected. They need to move to a four-bedroom house in the same area, which requires borrowing an additional amount on top of their existing mortgage. Their concern is whether the increased repayments will be manageable given their current childcare costs and whether they need to sell before they buy.

Structuring the Loan Around Your Cash Flow

The loan structure for an upsizing purchase should reflect how your income arrives and when your expenses peak. A split loan arrangement can give you stability on the majority of the debt while keeping flexibility on a smaller portion for offset benefits.

In the scenario above, the dental technician's existing mortgage was close to being paid off on their unit, which they planned to sell. However, settlement timing meant they needed bridging finance for six weeks. Rather than taking a traditional bridging loan with higher rates, their broker structured the new purchase with a split: 70% fixed for three years to lock in repayments during the period of highest childcare costs, and 30% variable with a linked offset account. The variable portion absorbed the proceeds from the unit sale at settlement, immediately reducing the loan balance and the interest charged.

This structure meant their repayments were predictable during the transition, and once the unit sold, the offset account reduced interest on the variable portion without locking those funds away. They kept liquidity for furniture, school costs, and the inevitable expenses that come with a larger home.

How Lenders Assess Income for Dental Technicians

Lenders calculate your borrowing capacity by assessing your income against a serviceability buffer, usually adding 3% to current variable rates. For dental technicians, this calculation can include overtime and allowances if they've been consistent for at least three months, though some lenders require six or twelve months of history.

If you're employed through a dental laboratory and receive regular shift allowances or overtime, providing payslips and an employment letter that confirms these are ongoing will allow most lenders to include them in your assessed income. If you operate as a contractor or through a company structure, lenders may require tax returns or financial statements, but several lenders in our panel can assess applications using alternative documentation for dental professionals who operate this way.

Your existing mortgage and other commitments will reduce your borrowing capacity more than your total income increases it. Clearing small debts like car loans or personal loans before applying can increase what you can borrow by a factor of five to six times the monthly repayment you eliminate. For a dental technician with a $15,000 car loan at $400 per month, paying that out before applying could increase borrowing capacity by $20,000 to $24,000, which might be the difference between needing to compromise on property size or location.

When to Sell Before You Buy or Buy Before You Sell

The timing of your sale depends on your equity position, your borrowing capacity, and whether you can manage two mortgages temporarily.

If you have enough equity in your current property and sufficient income to service both loans for a short period, buying before you sell gives you control over timing and removes the stress of temporary accommodation. If your borrowing capacity is tight or your equity is limited, selling first and renting briefly may be necessary, though this adds disruption during a period when stability matters for young children.

A bridging loan is a formal way to hold both properties, but it's often more expensive than structuring your new purchase to accommodate a short overlap. Some lenders will assess your new loan application assuming your current property is sold, allowing you to settle on the new property with the expectation that the old one will sell within 6 to 12 months. This avoids bridging loan interest rates while giving you time to market your property without pressure.

Offset Accounts and Principal Reductions During Transitions

An offset account linked to your variable rate portion lets you park the proceeds from your sale immediately after settlement, reducing the interest you're charged without locking the funds into the loan.

If you sell your current property and receive $180,000 after paying out your mortgage, depositing that amount into an offset account linked to a $200,000 variable loan portion means you're only charged interest on $20,000. The funds remain accessible if you need them for renovations, medical expenses, or education costs, but you're not paying interest on money you're not using.

This approach works particularly well for dental technicians who may face variable work hours or changes in employment structure. Keeping liquidity while minimising interest gives you flexibility during a period of transition.

Calculating What You Can Borrow When Upsizing

Your borrowing capacity for an upsize is not simply your income multiplied by a fixed number. Lenders assess your net income after tax, subtract your current living expenses using either your declared figures or a benchmark minimum, and then calculate how much you can service at an interest rate that includes a buffer above current rates.

For a dental technician earning $85,000 per year in base salary plus $12,000 in regular overtime, lenders will typically assess your income at around $95,000 to $97,000 after allowing for the variability of overtime. If you have $2,000 per month in childcare costs, a $500 per month car loan, and typical living expenses for a family of four, your serviceability will be assessed on a net basis after these commitments.

This calculation will determine the maximum loan amount you can access. If you currently owe $250,000 on your existing property and need to borrow $650,000 for the new purchase, lenders will assess whether your income can service the new loan assuming your current property is sold. If your equity from the sale is $200,000, your net borrowing is $450,000, which will be assessed against your income and commitments.

LMI and Equity Considerations When Moving Up

If your deposit from the sale of your current property is less than 20% of the new purchase price, you may need to pay Lenders Mortgage Insurance. Some lenders offer LMI waivers or discounts for dental professionals, which can reduce this cost significantly.

For a dental technician purchasing a $750,000 home with $140,000 in equity from their previous property, the loan to value ratio is approximately 81%, which would ordinarily trigger LMI. However, several lenders in our panel offer reduced or waived LMI for dental technicians and other dental professionals, particularly if your employment is secure and your income is well-documented. This can save between $8,000 and $15,000 on the upfront cost of purchasing, which can instead be directed toward furniture, moving costs, or kept in your offset account.

Pre-Approval Before Listing Your Current Property

Getting loan pre-approval before you list your current property lets you know exactly what you can borrow and removes uncertainty during the sales process.

Pre-approval for an upsizing purchase is typically conditional on the sale of your current property, but it confirms your borrowing capacity and gives you confidence when making offers. It also identifies any issues with your income documentation, existing debts, or credit file that can be resolved before you're under time pressure.

For dental technicians with variable income or complex employment structures, pre-approval is particularly valuable because it gives your broker time to present your application to lenders who understand your profession and can assess your income appropriately. This avoids the situation where you've sold your property, found a new home, and then discover your income hasn't been assessed correctly, leaving you short of the amount you need.
