The Lego House singer lets 13 flats and houses in London and has added a bar and restaurant.
Last year Ed, 28, raked in £342million to be the highest-earning musician.
A financial expert said: “He’s been incredibly shrewd by ploughing his money into property. And by focusing on London, where the market is still growing, he can charge top whack to renters.
“There’s every chance tenants are unaware they are handing money over to a multi-millionaire singer.”
Ed has bought the flats and houses through Maverick Properties, which he set up four years ago with his manager Stuart Camp.
Their restaurant Galicia is close to his eight-bed pad in Notting Hill, West London.
Ed and wife Cherry spend most time in “Sheeranville” near his childhood home in Suffolk.
