Overseas landlords have been deserting Britain owing to higher taxes, slowing house price growth and shrinking rental income on the back of the weak pound since the Brexit referendum.
Hamptons International, the estate agent, said that the proportion of homes let by an overseas landlord had more than halved in eight years, from 14.4% in 2010 to 5.8%.
London has experienced the biggest drop, from 26% to 10.5% in that time, with the share falling by 4.7 percentage points in the past two years.
