Rents will rise in the coming months as there will be a lack of available properties on the market, it has been suggested.
Jane Ingram, head of lettings at global real estate service provider Savills, said these rent increases will be particularly notable in the lower end of the market.
She said that some landlords who had been forced to rent out their property due to weak transaction levels were now taking their houses off the market so that they can sell them.
"Landlords who also have a toe in both the sales and lettings market are opting to sell rather than rent out their property if given the choice," Ms Ingram added.
Her comments are in contrast to the Residential Rental Price Index from Rentright which showed that the average rental price dropped this month.
It found that the average rent stood at £585 in May – a drop from £670 in April.
Meanwhile, the number of available flats went up by 2.8 per cent since March this year, according to the FindaProperty.com Rental Index from April 2009.
