The thing to remember about the buildings they have sold (aside from 360 Furman St.) is that these are the "outer buildings" the society was planning to sell back when trying to gain permission to build the 800,000 sq ft residence complex at 85 Jay Street.
There were 3600 Bethelites in Brooklyn.
Now its about 1400.
But some have been transferred to Wallkill, which will get more when the new residence is completed and they plan major expansion at the WEC in Patterson.
The Outer Buildings have not been needed in Brooklyn for a while now.
And like mentioned above, perhaps they don't want to have to keep paying the maintenance costs on these buildings they no longer need.
The actual major properties are the 117 Adams Street Complex, the Office Complex, and The main Bethel Residence block of buildings connected by underground tunnel. These are 124,107,97 and 119 Columbia Heights, plus the Towers Building at 21 Clark Street (79-99 Willow Street).
These are the ones they will wait to sell.
Cedars- I hope you can obtain the information needed to produce that graphic.
On a side note- The society had purchased property in Ramapo NY to build a new complex in addition to the later properties at Warwick and Tuxedo.
But they were unable to obtain tax free status there and decided not to build anything there.
I wonder if they will sell that property too?
