"Unless the stock being sold is replenished there is a limit to how sustainable this modest improvement in market turnover will prove to be"

Simon Rubinsohn, Royal Institution of Chartered Surveyors' chief economist, said in a statement: "Activity is now picking up which is encouraging, but unless the stock being sold is replenished there is a limit to how sustainable this modest improvement in market turnover will prove to be.

"And, unfortunately, the indications are that we are locked in a cycle where the lack of available properties on agents' books is itself deterring some potential vendors from thinking about putting their own property on the market.

"Against this backdrop, it is hard not to see prices continuing to move higher over the coming months and into the early part of 2016, notwithstanding the present concerns regarding the affordability of housing in some areas of the UK that are being highlighted by respondents," he added.
