How do you find out which New York City mayoral candidate is elite and out of touch? It’s apparently not the price of milk these days, but the typical sales tag on a Brooklyn home.

Two Democratic primary contenders, notably the ones steeped in housing and finance, bombed the question when asked by a New York Times editorial board member during a series of recent interviews for the newspaper’s endorsement for the June 22 election.

“Do you happen to know what the median sales price for a home is in Brooklyn right now?” board member Mara Gay asked during an April 21 sit down with former Obama housing secretary Shaun Donovan.

“In Brooklyn, huh? I don’t for sure. I would guess it is around $100,000,” Donovan replied.

“It’s 900,000,” Gay told him.

Ex-Citigroup executive Ray McGuire was also way off the mark.

“It’s got to be somewhere in the $80,000 to $90,000 range, if not higher,” he said.

Both men were pilloried on Twitter when the Times posted transcripts of the interviews Tuesday.

“How can you fix the city’s housing crisis if you’re this oblivious?” asked political strategist Monica Klein.

“I mean, do u even watch House Hunters?” quipped Brooklyn Councilman Justin Brannan (D-Bay Ridge).

The Grey Lady ultimately endorsed former Sanitation Commission Kathryn Garcia, whose answer was off by just $100,000.

“Oh, I don’t know this. I haven’t purchased in a long time. I’m going to guess $800,000,” Garcia said during her interview. Garcia owns a home in Park Slope, Brooklyn.

City Comptroller Scott Stringer, a Manhattan resident, was slightly over the target at $1,000,000.

Only Andrew Yang, another Manhattanite who famously wore a ‘Math’ button during his failed presidential campaign, guessed correctly.

“I know. I am the math guy. But this is, like, a median. This is, like, blowing my mind, this question. So median home — could be any size, right? So some of them would be very substantial. But you’re looking at the median, so you have to, like, whittle down,” Yang mused.

“I would just say that the median — it’s going to be something, like, much higher than it should be. So the number that popped into my mind is $900,000,” he said.

“That’s exactly right,” Gay responded.

Brooklyn Borough President Eric Adams, who’s neck and neck with Yang in recent polls and is a homeowner in the borough, said $550,000. Nonprofit executive Dianne Morales had a similar response with $500,000.

And Maya Wiley, a civil rights attorney, went way over the median price with her $1,800,000 guess, though that price is what Victorian mansions sell for in the Ditmas Park, Brooklyn, neighborhood she calls home.

Donovan later claimed in an email to the Times that he thought Gay was asking about “assessed value of homes in Brooklyn.”

“I really don’t think you can buy a house in Brooklyn today for that little,” he insisted.

Indeed, he’s right about that.

The real estate website Curbed did a search across the five boroughs and came up with just seven properties for the low six figure price. None were in Brooklyn. One was in Queens and the rest in The Bronx. Most of them were so cheap due to income restrictions and other purchase requirements.

The question was a local version of the 1992 query that tripped up President George H. W. Bush during a debate with Bill Clinton and Ross Perot.
