Ms Leishman said the company expected a quiet Christmas and first half of the new year but hoped to raise some rents in 2015.
"We would like to see the rental price increase in some areas, but at the end of the day, the market dictates the price.
"Something that you get good money for now, next year depending on what is available, you might not get the same price," she said. "It is a fickle industry and at the end of the day the market will pay what the market thinks the property is worth."
