The Hometrack survey shows a small rise in London prices offsetting falls in other regions. Hometrack said the trend looked set to continue through 2012 as the Olympics firmly focused the eyes of the world on London, and overseas buyers, in the midst of global uncertainty, continued to consider London a safe haven.

“A small rise in London offset falls in other regions. London looks set to buck the national trend again in 2012 thanks to overseas buyers providing a boost to prices in London’s prime areas.
“Elsewhere demand remains constrained by the uncertain economic outlook. Some agents have also reported an increase in down-valuations as surveyors exercise growing caution.”
