Just weeks after lifting mortgage rates by 0.25 percentage points, the big four banks and the Reserve Bank have done it again. On Tuesday, they added another $46 a month to the cost of servicing a $300,000 mortgage.

Each of the big four banks has announced plans to pass on the full rise by next week. The ANZ and Westpac's standard variable rates will jump to 6.31 per cent; the Commonwealth and National Australia Bank's rates will go to 6.24 per cent.

The changes will force a household with a $300,000 mortgage to pay $92 more a month than before the first rise last month. A household with a $500,000 mortgage will pay an extra $154.

Kellie Mossop from Regional Valuers said she definitely saw the second rate rise coming.

"It was fairly well predicted across the board," the local property valuer said.

"It's never a good thing for someone who owes a lot of money but it's a sign that the economy is improving and that's a great thing.

"The rates are still historically low and hopefully people have built these rises into their budgets."

Ms Mossop said all the talk of rising interest rates has not yet perturbed local property buyers from purchasing.

"There was quite a bit of discussion that rates were going to rise but it has not at all affected people's interest in property.

"People are still investing and purchasing property," Ms Mossop said.

Yass Valley Property's Andrew Curlewis told the Tribune he too expected the rate rise.

"They can only go one way," he said.

Real estate has been particularly strong of late, according to Mr Curlewis, and he does not suspect the additional 0.25 per cent rise will affect the confidence of local buyers too much.

"Real estate has been very strong the second half of this year - we can't get enough listings.

"Interest rates are still a fair bit lower than they were 12 to 18 months ago. They have to go up but they are still much better than they were."

The wording of the statement by the Reserve Bank governor, Glenn Stevens, this week indicated more rate rises are to come, although there might be a pause next month.
