UK annual house price softened to 2%.
Prices up 0.5% during the month, after taking account of seasonal factors.
London was the weakest performing region in Q2, with prices down 1.9% year-on-year.
Commenting on the figures, Robert Gardner, Nationwide's Chief Economist, said: "Annual house price growth fell to its slowest pace for five years in June. However, at 2% this was only modestly below the 2.4% recorded the previous month. "Indeed, annual house price growth has been confined to a fairly narrow range of c2-3% over the past 12 months, suggesting little change in the balance between demand and supply in the market over that period".
