Investing in a two-bed property in the North East achieves the highest yield at 5.5%, whilst the North West follows closely behind at 5.3%.
In London, the best average yields are seen across properties with one bedroom, at 4.6%.
Calum Brannan, founder and chief executive at Howsy, said: “As a landlord, maximising the profitability of your buy-to-let investment is as vital now as its ever been and property size and type are as important as location when it comes to doing so.
“While the two-bed property is traditionally the most popular amongst tenants and landlords due to the additional size without going overboard on costs, there is a slight regional variation in the capital.
“This is of course, due to the high rents you can secure in London even on a one bed and the overwhelming demand for properties that have seen even the smallest ‘studio flats’ rent for above average prices.”
