For capital and interest mortgages up to 75 per cent LTV, Natwest also raised its maximum loan to income (LTI) ratio to 5.5 times income for a single borrower earning more than £75,000 or for joint applicants earning more than a combined £100,000.
On residential loans, the bank said increased its maximum loan sizes for most LTV bands, allowing people to borrow a greater amount.
It will now lend an unlimited amount at 60 per cent LTV; up to £7.5m at 75 per cent LTV; up to £2.55m at 80 and 85 per cent LTV. In addition, it said it would lend up to £750,000 at 90 per cent LTV and up to £570,000 at 95 percent LTV.
Additionally, the stress rate on its buy to let five-year fixes and its buy to let like-for-like remortgages have both increased from 4.5 per cent to 4.75 per cent.
