Understanding Borrowing Power

Borrowing power is essentially the amount a lender is willing to loan you based on your financial situation. For someone earning a $100,000 annual salary, your borrowing capacity will depend on various factors beyond just your income. Lenders will consider your expenses, existing debts, credit score, and deposit size. Typically, with a $100,000 salary, you might be able to borrow anywhere between $500,000 to $700,000, but this range can vary significantly among lenders.

Factors Affecting Borrowing Power

Income and Expenses

Your income isn’t just your salary; it includes all sources of income, such as bonuses or rental income. Conversely, your expenses cover everything from living costs to existing debts. Reducing your expenses can significantly enhance your borrowing power.

Credit Score

A healthy credit score is crucial. Lenders use this to assess your creditworthiness. Ensure you pay all bills on time and reduce outstanding debts to maintain a good score. Regularly checking your credit report can help you spot and correct any discrepancies.

Deposit Size

The bigger your deposit, the less you need to borrow. A deposit of at least 20% is ideal, as it often means you can avoid Lenders Mortgage Insurance (LMI), which can save you thousands.

Interest Rates

Current interest rates also play a significant role. Even small changes in rates can affect your monthly repayments and thus your borrowing power. Keeping an eye on rate trends can help you decide the best time to apply for a loan.

Practical Tips to Maximise Borrowing Power

  • Reduce Debts: Pay off credit cards and personal loans to improve your debt-to-income ratio.
  • Boost Your Savings: A larger deposit not only increases your borrowing power but may also secure you better interest rates.
  • Consider a Joint Application: Partnering with someone else can increase your combined borrowing power.
  • Improve Your Credit Score: Regularly check your credit report and rectify any issues promptly.
  • Consult a Broker: Mortgage brokers can provide personalised advice and help you find the best deals across multiple lenders.

Common Mistakes to Avoid

  • Ignoring Expenses: Failing to track your spending can undermine your borrowing capability.
  • Not Checking Your Credit Score: Overlooking your credit health can lead to unexpected loan rejections or less favourable terms.
  • Overcommitting: Borrowing to your maximum capacity can be risky if interest rates rise or your financial situation changes.
