There have been reports of buy-to-let investors rushing to snap up properties before a three percentage point stamp duty hike comes into force for this sector in April.

Meanwhile, Jeremy Leaf, a north London estate agent and former chairman of the Royal Institution of Chartered Surveyors (Rics), said: "On the ground, we have seen a gradual slowdown in the market over the past week or so.
"This is happening in anticipation of the stamp duty increase for investors and second home buyers."
