A new survey suggests 40 per cent of landlords derive their main source of income from letting property.
The study of 500 landlords conducted earlier this month reveals that just over a third of landlords have full time jobs and another five per cent have part time employment. The rest are either retired or full time landlords.
The research also shows that around 20 per cent of landlords enjoy annual yields of between 15 and 30 per cent - a huge figure - while a quarter of landlords have yields between five and 10 per cent.
The HomeLet rental index show that rents across the UK are 10.2 per cent higher than a year ago. The average rent on a tenancy signed in the UK during the first quarter of 2015 was £902, compared to £819 for tenancies signed during the first quarter of 2014.
Rents are higher in every region of the UK except Wales compared to a year ago.
These high returns indicate why buy to let remains such a draw to investors and why some believe they can derive a continuing income from rents alone, says a spokeswoman for the agency that commissioned the survey, Property Let By Us.
