Understanding Mortgage Affordability

When considering a $900,000 mortgage, the first step is to evaluate your financial capacity. Australian lenders typically assess your ability to repay a mortgage based on several factors, including your income, expenses, existing debts, and credit history. To afford a $900,000 mortgage, your annual income should ideally be substantial enough to cover monthly repayments comfortably while maintaining a reasonable lifestyle.

Calculating Your Monthly Repayments

The monthly repayment amount for a $900,000 mortgage will vary depending on the interest rate and loan term. For instance, at an interest rate of 6% over a 30-year term, your monthly repayment could be approximately $5,397. It’s vital to use a mortgage calculator to simulate different scenarios, which can help you understand how changes in interest rates or loan terms could affect your payments.

Key Income Requirements

Australian lenders generally follow a debt-to-income (DTI) ratio guideline to determine borrowing capacity. A DTI ratio of 30-40% is often considered manageable. This means if your annual income is $150,000, your monthly income is approximately $12,500, and a $900,000 mortgage at 6% interest would take up around 43% of your monthly income, which may be higher than recommended unless your expenses are significantly lower.

Practical Tips for Affording a $900,000 Mortgage

  • Budgeting Wisely: Create a detailed budget that accounts for all expenses, including loan repayments, insurance, and maintenance. This will help you determine if you can comfortably manage a $900,000 mortgage.
  • Improving Your Credit Score: A good credit score can lead to better interest rates. Ensure your credit report is accurate and address any discrepancies.
  • Increasing Your Deposit: A larger deposit reduces the loan amount, making repayments more manageable and potentially lowering interest rates.

Common Mistakes to Avoid

  • Underestimating Expenses: Forgetting to account for ongoing expenses such as property taxes, maintenance, and insurance can strain your budget.
  • Ignoring Interest Rate Changes: Variable interest rates can increase over time. Consider fixing your rate for a period to avoid potential hikes.
  • Overextending Financially: Borrowing the maximum amount you qualify for can be risky. Ensure there’s room in your budget for unexpected expenses.
