The UK's biggest mortgage lender today doubled its forecast for house price rises before the end of the year but said it still expected the market to slow.

Halifax is now predicting property prices will end 2004 16 per cent higher than they started it, well up on the eight per cent rise it expected at the beginning of the year.

It said the market remained particularly strong in the North, with price rises outside the south accounting for around 70 per cent of the 11 per cent increase in the cost of property seen so far this year.
