KensingtonLondon and top-end property lead housing price rise
The BBC reports that UK house prices rose by 0.3% in July compared with a year earlier and by 0.8% on the previous month, the Land Registry said.
London saw the biggest rises, with prices up 6.5% on the year.
The number of properties worth more than £1m sold in the year to May in England and Wales more than doubled to 562, the registry added.
The average UK house price in July was £162,900, up from £161,777 in June.
But a number of regions saw sharp falls in prices. In the northwest, prices dropped by 3.9% year-on-year, while in the northeast, they fell by 3.8%.
Yorkshire and the Humber (-2.5%), the southwest (-1.9%), Wales (-1.3%) and the west Midlands (-0.8%) also saw prices fall.
Analysts said the Land Registry's data chimed with other house price indexes that showed a stagnant market in the UK as a whole.
"The market remains extremely fragile and the long-term forecast for UK homeowners is pretty gloomy," said independent housing expert Henry Pryor.
"It seems clear that sellers have been duped by the summer sunshine into asking more than they ought and it now seems inevitable that the proportion of those selling who have to reduce their asking price will rise from the 30% who have already had to do so at least once."
