Brexit continues to drag on market activity as estate agents today report a continuing decline in buyer demand, instructions, listings and sales.

The latest RICS Residential Market Survey for March shows that more of its member agents have seen a drop rather than a rise in buyer demand for the eighth consecutive month, which also kept agreed sales negative.

The average time taken for a residential property to sell, from listing to completion, remained unchanged at 19 weeks, the longest since this series was introduced in 2017, RICS said.

This figure is highest in the south-east at 21.5 weeks on average.

Property supply has also become progressively weaker, with more agents reporting a drop in listings.

Despite this, surveyors were still more hopeful of a rise rather than a fall in sales activity over the next 12 months.

Much of the blame for the market slump was placed on Brext uncertainty, but RICS is also warning of a slowdown in house building.

Simon Rubinsohn, chief economist for RICS, said: “Brexit remains a major drag on activity in the market with anecdotal evidence pointing to potential buyers being reluctant to commit in the face of the heightened sense of uncertainty.

“Whether any deal provides the shift in mood music envisaged by many respondents to the survey remains to be seen, but as things stand, there is little encouragement to be drawn from key RICS lead indicators. We expect transactions to decline on this basis.

“Arguably more significant still are the signs that developers are continuing to adopt a more cautious stance with the trend in new residential starts now flatlining.

“Against this backdrop, there is little possibility of delivering the uplift in supply necessary to address the ongoing housing crisis.”
