  • Full Time or Part Time
  • Liabilities or Expenses

  • Existing loan repayments and arrangements

  • How many?
  • What are their ages?
  • There are also other factors included within the borrowing power calculation to ensure your ability to service the loan completely.

    When lenders assess your ability to repay the full home loan with applicable interest rates, they need to make sure it is for the purpose of ensuring long term affordability over the entire term of your loan, not just today.

    Frequently Asked Questions

    If you have been able to save a large deposit to buy your home, a home loan lender or bank will more likely lend you more. As a general rule, most mortgage lenders will generally only let you borrow less than 90% of a property’s value. For example, if a property costs $800,000 and you have a $80,000 the deposit, the home loan lender in Australia will only lend you $720,000.

    In most situations when you have a guarantor or equity on the property, you can borrow 100% of the purchase price. Otherwise, you can only borrow a maximum of 90% of the property value.

    A ballpark calculation will give an estimate of $2000 per month which is equal to 30% of $80,000 annual gross income divided by 12. With a mortgage at 3% p.a. this equates to a loan amount of $450,000. A 10% deposit towards the home loan will equates to $45,000 and this will make the maximum affordable property price to be $495,000. Please note, this is an estimate. Please talk to a good mortgage broker in your area to give an accurate amount you are able to borrow.

    The equity you have in an existing property or amount of savings can substantially improve your borrowing power and it’s a big advantage for those purchasing a second home or an investment property.
