Research carried out by the National Landlords Association (NLA) found that 30% have not made up their minds on how will they vote, with the figures evenly split among those who have decided, showing that 35% are planning a vote to remain and 35% hoping to leave.

Landlords were also divided on whether EU membership would be beneficial to their future business prospects, with 53% believing that would have a positive impact and 47% believing it would be harmful.

Richard Lambert, chief executive officer at the NLA, warned that it is now crunch time for landlords to make a decision, with the referendum taking place on 23 June.

“Landlords, much like the rest of the British public, are divided on how they will vote in the EU referendum which means the decision looks to go down to the wire,” said Lambert.

“The remain and leave campaigns have both had difficulty persuading the public on the benefits or hazards of a Brexit vote, and they have struggled to provide any clear analysis about the impact exiting the EU would have on the buy-to-let market.

“As a result, landlords appear more likely to vote in this referendum based on their attitudes to issues such as national security, trade and immigration, rather than the effect on the UK property market or their businesses.”

Regionally, more landlords in London intend to vote to remain in the EU than anywhere else in the UK, at 45%. However, more landlords in the North East intend to vote to leave than anywhere else in the UK, at 44%.

In Scotland, 42% want Britain to remain in the EU and 30% want to leave, while in Wales 40% want to leave and 20% want to stay. The remaining percentages of voters were undecided.
