Making extra repayments, paying fortnightly instead of monthly can save thousands in interest over the term of your loan.

Mr Projeski said if a dual-income household earning $100,000 a year placed their wages on the account of their $300,000 30-year mortgage at the current standard variable rate of 5.91 per cent and withdraw $700 a week for expenses, the loan would be repaid in eight years, and the borrowers will save $264,000 (in interest).

Evaluating account keeping fees was also a priority according to Mr Projeski.
