The Royal Institution of Chartered Surveyors' (RICS) released its house price data for the U.K. on Thursday. The monthly house price balance dropped to +42% in March from +50% in February.

The RICS noted that uncertainty increased due to the impact of Stamp Duty changes, the EU referendum and devolved elections.

"As expected, the buy-to-let rush has now run its course and, as a natural result, the market is starting to slow," RICS Chief Economist, Simon Rubinsohn, said.

"The EU referendum, is likely to be an influencer in terms of the damper outlook for London in particular," he added.
