Pat Dolan and his dad, Charles, probably have billions between them — after selling Cablevision to Altice NV for $17.7 billion — but they are still “renters” when it comes to a home for their just-acquired Newsday Media Group.

Under terms of the 2008 deal whereby Tribune CEO Sam Zell sold the paper to the Dolan-controlled Cablevision for $650 million, the Chicago investor kept the valuable real estate under its HQ.

That deal stayed in place when Cablevision was sold to Altice — and when the Dolan family bought back the papers.

Newsday Media Group continues to bleed red ink, reportedly losing $135.5 million over the past three years, according to the Long Island Press, a weekly.
