After Mayor Mamdani promised to freeze rents for two years in nearly a million rent-stabilized apartments, the lefties on the Rent Guidelines Board saluted and delivered for him.

Here is some of how he gloated afterward:

“This is a historic victory for New York City tenants. After reviewing the data and hearing from New Yorkers across the city, the independent RGB has delivered a freeze on one-year leases, and the first-ever freeze on two- year leases in our city’s history. This is the relief that working people across our city deserve.”

He also vowed that, “I’ll continue working to deliver a more affordable city by building and preserving affordable housing, lowering building operating costs like insurance, and ensuring tenants know their rights.”

In plain English, he’s warning that private-sector owners must realize they have no rights to cover their costs, let alone to make a profit.

And oh, by the way, developers shouldn’t even think of building rental units here. The free housing market in New York is dead.

Long live the revolution!
