More than a third of landlords said they would stop investing in their properties if rent controls are introduced, according to Landbay.
Out of those polled, 37% said they would stop putting money into their current properties.
There are 4.7 million homes in England’s private rented sector, meaning 1.75 million could see less investment if the Renters’ Rights Bill goes ahead.
Rob Stanton, sales and distribution director at Landbay, said: “It’s really important that we go into the Bill with our eyes open.
“Rent control always has unintended consequences – and let’s be frank, that is exactly what we are signing up for with the Renters’ Rights Bill.
“We can see it in areas that have adopted it like Berlin, New York, and San Francisco.”
Stanton added: “Trying to manipulate the market will lead to landlords leaving their properties untouched and not investing in them, potentially, lowering the quality of the housing stock.
“In a free market, rents reflect demand and scarcity. That will no longer be the case when the Bill comes in.”
