Home buyers are set to receive a borrowing boost in the order of $100,000 because of a combination of looming changes to lending standards and interest rate cuts, new modelling shows. A single borrower with an annual income of $80,000, no other debts and average - or below - living expenses could today expect to be approved for a maximum loan amount of $512,000. This would increase to $567,000 under the proposed relaxation of loan serviceability rules flagged by the banking regulator last week, according to modelling by Independent Mortgage Planners.

NAB has slashed all its fixed home loan interest rates. The move comes a day after the Big Four bank announced it expects a supersized 0.50 per cent rate cut from the Reserve Bank of Australia (RBA) in May.
