Key Takeaway

Mascot apartment owners upgrading to a family home can usually safely borrow around 4.5–6 times gross household income, assuming a 20% deposit and repayments capped near 30–35% of after-tax income. Under APRA rules, lenders must test your loan with a 3% interest rate buffer, which often reduces the practical limit. Buyers should stress-test repayments, keep 6–12 months of living costs in buffers, and base decisions on their personal safe limit rather than the bank’s maximum approval.

Most Mascot apartment owners can safely borrow around 4.5–6 times gross household income to move into a family home, as long as repayments stay near 30–35% of after‑tax income and you keep a solid cash buffer. The bank may offer more, but APRA’s 3% buffer and your real lifestyle costs should set your true ceiling.

Here’s how to work out a decision‑grade number you can actually use this week.

Mascot couple calculating safe borrowing to upgrade from apartment to family home. Work out both your bank maximum and your safe borrowing limit before house hunting in Mascot.

Step 1: Know your bank maximum vs your safe limit

Banks start with your income, then apply HEM living costs, other debts and a 3% rate buffer. That gives you a bank maximum – not a recommendation.

Your safe limit is usually lower and should be based on three guardrails:

Debt-to-income (DTI) ratio – target 4.5–6× gross income for owner‑occupiers.
Repayment ratio – keep all home loan repayments near 30–35% of net income, even when rates are 3% higher.
Buffers – hold 6–12 months of stressed living costs plus all loan repayments in cash or offset (see similar guidance in our Alexandria piece: /insights/alexandria-apartment-to-family-home-safe-borrowing-limits).

If any one of those blows out, you’re stretching too far – even if the bank still says “yes”.

Step 2: Run the Mascot numbers on a real example

Say you’re a Mascot couple with: - Combined gross income: $260,000 - Current Mascot unit: $900,000 estimated value - Remaining loan: $520,000 - Savings in offset: $40,000 ### Usable equity for the upgrade If you sell the unit and buy with a 20% deposit plus ~5% costs: - Net sale proceeds after paying out loan: about $380,000 before selling costs - After 3% agent + marketing and other sale costs (say ~$30,000): $350,000 - Plus savings: $390,000 total cash On a $1.6m Mascot house, a common price point: - 20%…

Frequently asked questions

Most Mascot upgraders can safely borrow about 4.5–6 times gross household income, assuming they have at least a 20% deposit plus costs and solid cash buffers. The higher end of that range suits more stable, higher-income households with low other debts. Always cross-check the bank’s maximum with your own comfort level based on stressed repayments.

It can be, but only if total home and investment repayments stay near 30–35% of after-tax income under a 3% rate buffer. If keeping the unit pushes you above that, or leaves you with less than 3–6 months of cash buffer, you’re likely over-stretching. In those cases, selling or staging the move is usually safer.

APRA requires banks to test your ability to repay at an interest rate at least 3 percentage points above the actual rate. This reduces your maximum borrowing power compared to calculations at today’s rates and can be a big constraint for Mascot upgraders. It’s a safety net, but you should still run your own stress tests using your real spending.
