Buyer demand hit a three-year low in the run-up to the EU referendum, and agents are predicting tough times ahead.

The NAEA’s May Housing Market report revealed that an average of 304 house hunters registered per member branch in May, down 6% from April, and the lowest recorded since November 2013 when 292 buyers were registered per branch.

On an annual basis demand has fallen 21% since May 2015.

This has at least boosted supply with 37 properties available per branch in May, up from 35 in April.

Meanwhile, the number of sales agreed in May decreased to an average of eight per branch, a drop from nine in April and falling to the same level seen during the seasonal slowdown in January.

First-time buyers seem to be bucking the trend, though, as other reports have suggested.

Although the number of house hunters registered per branch and sales agreed fell in May, sales to first-time buyers increased marginally, accounting for 27% of the total sales completed last month, up one percentage point from April.

With a Brexit now looming, two in five agents are predicting that house prices will fall and 30% expect a decrease in demand.

Mark Hayward, managing director of the NAEA, said: “The EU referendum without doubt meant that May was a month of uncertainty for potential house buyers – demand dropped significantly and is currently at the lowest level we have seen in the last three years.

“As a result of the vote for a Brexit, we expect international investors to look a lot harder at the UK as a potential market to buy in and this will have a knock-on effect on the house building sector, as investments may be delayed or put off completely.

“Although in the short term we believe that house prices will remain stable, we cannot be certain about the next quarter as political uncertainty and market unrest could affect the housing market.”

Hayward warned that the Leave vote could exacerbate the skills shortage and lack of homes being built as there will be less migrant labour, adding: “This means that in the longer term, something will need to give which regrettably could mean a surge in house prices or buyers struggling to find a suitable property in order to move or get that first foot on the ladder.”
