Upsizing home loans for growing families
Outgrown your place? We'll help Bankstown & South West Sydney families finance the move to a bigger home.
Need more room? Let's plan your next move.
A new baby, kids who need their own rooms, working from home, parents moving in - there are plenty of reasons a home that once felt perfect starts to feel tight.
At Infinity Mortgage Brokers, we help families across Bankstown and South West Sydney plan the finance for a bigger home, so the move up feels exciting instead of overwhelming.
How do I finance a bigger home?
Upsizing means juggling a sale, a purchase and a larger loan. We'll help you work out:
- How much equity you have in your current home
- What you can comfortably borrow for the next one
- Whether to sell first or buy first
- If a bridging loan could help with timing
- Stamp duty and the other costs of moving
- What your new repayments will look like
We'll run the numbers before you start inspecting, so you're shopping with a budget you can trust.
Should I sell first or buy first?
There's no single right answer. Selling first gives you certainty about your budget. Buying first means you won't miss the right home, but you'll carry more risk while your current place sells.
It comes down to the market and how comfortable you are with risk. We'll lay out both options with real figures, so the choice is clear.

How do I finance upsizing to a bigger home in South West Sydney?
You finance upsizing to a bigger home in South West Sydney with the equity from your current home plus a larger loan. The steps are to confirm your equity, test your borrowing capacity and choose the order of sale and purchase.
Step one, confirm your equity
A current valuation shows how much your sale should release toward the next deposit and costs.
Step two, test the larger loan
The lender checks the new repayment against your income and living costs, with its buffer added. This sets your real budget.
Step three, choose the order
Sell first for certainty, or buy first with a bridging loan if the right home appears before yours has sold.
Where families are looking

Setting your budget
Infinity Mortgage Brokers works through all three steps with you before you start inspecting.
Can I use equity in my current home to upsize?
Yes, you can use the equity in your current home to upsize, and it is what funds most upgrades. Usable equity is generally 80% of your home's current value less the amount you owe.
Why 80%
Staying at or under 80% of the value keeps you clear of LMI on the new loan.
Values have not risen evenly
A house in Roselands or Beverly Hills may have gained more or less than a unit in Riverwood or Narwee. The starting point is a current valuation, not an online estimate.
Using equity as a deposit
Equity can fund the deposit on the next home before your current one sells. If you sell first, it is released to you at settlement.
Getting a firm figure
Infinity Mortgage Brokers in Bankstown can order valuations through several lenders before you apply. More in our guide to using equity to buy a home, and families comparing areas can read the best suburbs for schools.
Is it better to buy first or sell first when upsizing?
Neither buying first nor selling first is always better when upsizing. Selling first gives certainty, while buying first lets you secure the right home when it appears.
Selling first
You know exactly what you have to spend and never hold two loans. You may need to rent for a while or negotiate a long settlement.
Buying first
Bridging finance covers the overlap. You carry the risk that your sale takes longer or brings less than planned.
What decides it
Market conditions and your tolerance for risk decide it. In a rising market, buying first protects you from being priced out. In a slow market, selling first is safer.
Seeing both in figures
Infinity Mortgage Brokers puts both scenarios in front of families from Wattle Grove to Picnic Point with actual figures. Our guide to buying before you sell goes through the detail, and our guide for young families covers budgeting.
How much will my repayments rise with an upsizing home loan?
Your repayments generally rise with an upsizing home loan because the loan is larger. How far they rise depends on the equity you bring across from your current home.
The role of your sale
The more your sale releases, the smaller the new loan and the gentler the increase.
Costs beyond the repayment
A bigger property usually means higher council rates, insurance and upkeep, so include them in the budget.
How the new loan is tested
The lender adds its serviceability buffer to the rate and checks the repayment against your income and living costs.
A repayment you can live with
Infinity Mortgage Brokers aims for a repayment that suits your household, not one that merely passes the calculator. Families from Narwee to Mortdale can test scenarios with our mortgage payment calculators or read how to increase your borrowing capacity.
