From a UK perspective , I also wonder about the new UK Bethel - they have 584 apartments there housing up to 900 people. I am still in touch with a PIMO JW who has worked on the site & he is baffled as to what exactly the 900 workers will do , bearing in mind that no printing is taking place - a question also raised ( but not answered ) at a planning meeting with the local authority ( below ). He asked a member of the UK branch committee who said that "Jehovah will show the way."

My friend reckons as a distribution hub for German produced literature and a film studio they could probably get by with 300 maximum very comfortably - probably less.
He reckons that in a couple of years a lot of these Bethelites will be getting kicked out - it would be very easy for the Society to sell off the accommodation blocks which are some distance from the HQ ( they also own 200 acres of non developed land and say they have "no current plans at the moment" to develop it so could build new accommodation blocks there if required ).
584 studio style apartments would easily fetch over £100K each - that's upwards of $100 million from a build cost a fraction of that. The Society are already selling off the 18 flats in Wood Street , Chelmsford that supposedly was long term additional accommodation https://ibsaproperty.com/
Increasingly nowadays the Society are basically a real estate development and trading company using free labour to develop property & free of capital gains tax to flip. It's such a simple model.
