Now that he’s moved on up to Gracie Mansion, Mayor de Blasio will put his Brooklyn home up for rent starting Thursday, The Post has learned.

The 100-year-old brownstone in Park Slope is being offered for $4,975 a month, the Mayor’s Office confirmed.

“You’re getting a lot for what they’re paying,” the home’s Realtor, Tricia Webster of Brooklyn Properties, told WCBS/Channel 2.

“It’s living large,” Webster said. “In the city, whenever you have a private garden and three-plus, maybe a fourth bedroom, that’s living large.”

A drawback: it has just one bathroom.
