The firm’s research amongst landlords found, while the majority expected an increase in rates, 42 per cent believed interest rates would rise by less than two per cent.

Only one in 10 (10 per cent) expected to see interest rates rise by two per cent or more. However, a rise in interest rates was the biggest concern for 29 per cent.

However, buy-to-let investors have some concerns about what 2015 may bring. When asked for their number one concern, an increase in interest rates topped the poll (29 per cent), closely followed by future changes in laws and legislations for landlords (26 per cent).

A further nine per cent were most concerned about the impact of a change of government ahead of the general election. Only one in five (20 per cent) of investors had absolutely no current concerns.

Steve Bolton, chairman of Platinum Property Partners, said: “A rise in interest rates is one of landlords’ main concerns for 2015 yet the majority don’t anticipate that these rises will be dramatic or unaffordable.

“As a result, our research reveals that the sector will continue to grow next year, with two in five planning to add to their portfolio despite a likely interest rate rise.”
