Borrowers will need a deposit of 10 per cent of the bank's valuation, and funds to cover transaction costs, if they wish to borrow from ANZ.The bank on Friday advised brokers that from today the maximum loan to valuation ratio on new home loans funded by the bank will be 90 per cent, down from 95 per cent. The shift in credit policy applies to home loans funded by ANZ's Origin unit as well, where mortgage managers look after the loans.A couple of weeks ago the bank reduced the maximum LVR on low doc loans to 60 per cent from a prior limit of 80 per cent.
