It’s quite common for temporary residents of Australia to have either a business, investment property or pension that provides them with an income from outside of Australia. They often use this income to help them to pay their mortgage in Australia.
Not every lender will accept your foreign income in their assessment! Others will only accept your income if you’re an Australian resident for tax purposes and have declared your foreign income on your Australian tax returns.
However, some lenders have a simplified income verification process and can accept foreign tax returns, foreign pension statements or rental income receipts, as evidence of your income. They’ll usually use 80% of this income in their assessment to allow for exchange rate fluctuations.
