The Commonwealth Bank of Australia has informed mortgage brokers that new borrowers' existing debts and their incomes are to be assessed more stringently.
CBA will apply a servicing loading of 20% to all repayments on existing home loans and lines of credit held by customers.
The 20 per cent loading means repayments that were assessed at $1000 a month will now be assessed at $1200 a month.
CBA also said it would accept only 80% of income from overtime, bonuses, and investment income when it is assessing home and investment loan applications.
