What Income Do You Need for a $900,000 Mortgage?
| Borrower Type | Approximate Income Needed |
|---|---|
| Single borrower, no HECS, no dependants | ~$160,000–$200,000 |

HECS impact: Borrowers with significant HECS debt face mandatory repayment rates that reduce assessable income. At incomes above $151,201 (FY2025–26), HECS repayment is 10% of gross income — this materially reduces borrowing power.
What Does a $900,000 Loan Buy?

- A median-priced detached house in established Perth suburbs
- A mid-range house in outer Sydney

Extra Repayments — Impact on a $900,000 Loan
| Extra Monthly Repayment | Years Saved | Interest Saved |
|---|---|---|
| $200/month | ~2 years | ~$86,000 |
| $500/month | ~5.5 years | ~$205,000 |
| $1,000/month | ~10 years | ~$360,000 |
| $1,500/month | ~14 years | ~$472,000 |
At $900,000, an extra $500/month saves over $205,000 in interest and cuts more than 5.5 years from the loan. Making extra repayments in the first five years is especially powerful because interest charges on the full principal are at their highest.
Lenders Mortgage Insurance at $900,000
For borrowers unable to contribute a 20% deposit ($225,000), lenders mortgage insurance (LMI) applies. LMI premiums at $900,000 are significant:
- At 90% LVR (10% deposit, $1,000,000 property): LMI premium is typically $20,000–$35,000
- At 95% LVR (5% deposit, ~$947,000 property): LMI premium may exceed $40,000
LMI is usually capitalised into the loan, adding to your repayments. At $900,000 it is generally worth making every effort to reach a 20% deposit before purchasing to avoid this cost. See the LMI calculator for an estimate.
