Annual house price growth slowed in August as calls grow for a reform of property taxes in the Autumn budget.

The annual rate of growth in UK property prices dropped to the joint lowest this year, according to data from lender Nationwide, while the more volatile month-on-month change showed prices dipped by 0.1% compared with the previous month.

The sluggish picture comes amid reports that the government is considering an overhaul of stamp duty and other property taxes a bid to raise more money and boost the housing market.

Robert Gardner, chief economist at Nationwide Building Society, told the BBC the UK needs a tax system that "allows people to move more effectively".

"It's definitely worth looking at UK property taxes," he added.
