Mayor de Blasio’s ties to the Brooklyn Democratic boss he teamed up with to anoint the next City Council speaker run all the way to Hizzoner’s doorstep, The Post has learned.
Since 2012, de Blasio has refinanced both homes he owns in Park Slope through the firm where Brooklyn Democratic leader Frank Seddio formerly served as vice president — Wall Street Mortgage Bankers.
Public records show that the most recent deal came just three days after de Blasio’s primary victory on Sept. 10, when he refinanced his 11th Street home with the firm for $625,000.
In June 2012, he had refinanced another home his family owns down the block with Wall Street Mortgage Bankers for $630,000.
Each home has been refinanced multiple times, according to public records.
Seddio, a former state assemblyman who briefly worked as surrogate court judge in Brooklyn, joined the mortgage firm in 2007.
In 2011, he and longtime law partner Frank Carone, who serves as counsel to the Brooklyn Democrats, joined the law firm Abrams Fensterman, which shares a Lake Success, LI, address with the mortgage company.
Seddio has since left law firm.
Asked about the refinancing deals, de Blasio aides said it was a coincidental case where de Blasio’s broker used Carone’s brother as the title guy and referred him to Wall Street Mortgage Brokers.
They declined to provide the rates of the loans.
“Six degrees of separation is alive and well in Brooklyn,” said de Blasio spokesman Phil Walzak. “The refinancing was totally legitimate and above-board.”
Last month, de Blasio got Seddio to break from the Queens and Bronx Democratic leaders to back East Harlem City Council member Melissa Mark-Viverito for council speaker, according to multiple sources.
The fiercely liberal Mark-Viverito, a longtime ally of de Blasio, was the first member of the council to back his seemingly long-shot bid for mayor.
Seddio’s support is said to have swayed enough council members to give Mark-Viverito 30 votes — four more than the 26 needed to become speaker in Wednesday’s scheduled vote.
“It’s a good, working relationship,” de Blasio said when recently asked about his ties to Seddio.
In return, Seddio was promised powerful council chairmanships for his Brooklyn members, according to sources, and is expected to get a large say in who staffs back-office positions in the council.
Seddio and Carone did not immediately respond to requests for comment.
