Two-bedroom flats are the most common properties on the lettings market, landlordzone.co.uk reports.
New research from Experian found that the two-bed flat proved to be the most popular with tenants as many more take to the private lettings sector for their next home.
The study found that 40 per cent of homes that were let in Q1 2012 were flats, pushing semi-detached and terraced houses into second and third place respectively.
In the period between January - March, over 67,000 flats were let out nationwide, whilst semi-detached houses totalled just 21,800 and terraced houses accounted for 20,900.
Letting agents are also expected to see more prospective tenants asking for two-bed properties than any other, as these are the most common with renters. Over 35 per cent of all the properties let in Q1 2012 had two bedrooms, whilst three-bed places came second; accounting for 25.6 per cent of the market.
In total, the number of rental properties saw a rise of 6.34 per cent on the figures taken at the same time in 2010. Meanwhile, properties being offered for sale saw a 2.53 per cent decline, rman.co.uk reports. Analysts have claimed that with the trend showing no signs of slowing, it may just be a few years before the number of properties being offered for let outnumber those being sold.
