Eric Hadar has signed a contract to buy the Brill Building at 1619 Broadway for $185 million.

The sellers are Ofer Yardeni and Joel Seiden’s Stonehenge Partners, along with Invesco of Texas.

Hadar and Abraham Merchant and Richard Cohn of Merchants Property Group, signed a contract to buy the building last week, sources said.

The direct deal is being completed with investment brokers Douglas Harmon and Adam Spies of Eastdil Secured and may have begun as a retail play.

Sources said the group intends to bring the 175,000-square-foot building back to its roots with pre-builts targeting budding music and entertainment companies. Colony Records recently vacated the retail portion of the building; with a spread from the basement to the third floor of more than 45,000 square feet, it could be the most valuable portion of the asset.

In its 1950s and ’60s heyday, the building’s offices were filled with agents, publishers and rehearsal studios.

Singer-songwriter Paul Simon still maintains his office there.

No one could be reached for comment at press time.

Once an active investor, Hadar previously owned both the Citigroup Building and the LVMH Building at 57th Street and Fifth Avenue.

A downtown dorm currently used by Pace University is on the market through Jimmy Kuhn, David Colen and Lawrence “Chip” Porter at Newmark Grubb Knight Frank. The former office building at 55 John St., and its income stream, could bring in $90 million for seller Yitzchak Tessler.

The dorm is entirely leased to Educational Housing Services, which has an agreement to provide Pace with 285 fully furnished dorm rooms. Not like the dorm rooms you lived in years ago, these all have flat-panel TVs with built-in game consoles, small desks, captain’s beds and full-size refrigerators.

There is also a small H&R Block office on the ground floor for when the students graduate and finally earn some dough to pay back their loans.
