Foreclosures have spiked a remarkable 433 percent in Brooklyn this year.

From January through September, 453 foreclosure auctions were scheduled, up from 85 in the same period last year, according to ­RealtyTrac.

A recent one-month comparison shows an even more dramatic percentage rise.

This September, there were 83 scheduled foreclosure auctions — up from 14 in September 2014, a 493 percent increase, according to RealtyTrac.

The spike is counter to a national trend that has seen a drop in foreclosure auctions to a more than nine-year low, added Realty­Trac VP Daren Blomquist.

Ironically, the hot Brooklyn real-estate market is spurring the rise.

“There was a backlog of foreclosures in Brooklyn and they were finally pushed through because people can [now] resell the homes and recoup their losses,” said Realty­Trac exec Ginny Walker.

The incentive to foreclose and then flip the acquired properties is huge.

The average flipping profit rose dramatically in Brooklyn. It is up 51 percent to $238,412 this year.

“The bottom line is that the Brooklyn market represents a perfect storm for property flipping right now,” Blomquist said.
