Landlords have faced continued legislative change and increasing costs over the last few years, and many are either having to pass the costs on to tenants or exit the market.
In November, the East of England was the highest region for landlords selling up, with eight per branch, compared to the national average of four.
David Cox, chief executive of ARLA Propertymark said: “More than three quarters of ARLA Propertymark members think the number of landlords operating in the private rented sector will fall even further next year as they are driven out by rising costs.
“It’s therefore very likely that we’ll see the national average increase in line with what we’re seeing in the East of England.
“We’re all striving for the same end goal of improving the private rental sector for consumers, but the only thing which will truly create a better – fairer – market, is a dramatic increase in supply.”
