Republican mayoral candidate Paul Massey wants to impose a stricter means test on rent-regulated tenants, saying too many wealthy residents are gaming the system.

“It’s an old system. It leaves 100,000 [to] 150,000 people — wealthy people — in apartments that should have some means testing,” Massey, who co-founded a real-estate brokerage firm, told The Post editorial board Tuesday.

“That’s tying up a lot of housing, an awful lot of housing, and artificially propping rents up.”

Under current state law, rent-stabilized apartments can be deregulated when a tenant’s income hits $200,000 for two consecutive years and the rent is already $2,700 or more.

Massey, who did not specify what the income limit should be, said he supports rent regulations for low- and moderate-income New Yorkers who “desperately need our help.”

He also took at a shot at his Republican primary opponent, Staten Island Assemblywoman Nicole Malliotakis.

“She has been a career politician,” he said. “She could end up being another Bill de Blasio. That’s not what we want.”

Malliotakis responded: “I’m sure he’s frustrated that he’s spent millions of dollars and is not getting any traction.”
