Investment earnings made by a non profit org need to be re-invested in the org to remain non-taxable. They will likely be pouring millions into the new cult compound, but I really don't see how they will be able to put the full $800+ Million they've made already in property sales in Brooklyn so far Into just that one project. Perhaps they will build more in other countries?
This brings up an interesting problem for them though. They all of a sudden have a pant load of liquid cash, which must be spent or re-invested. I suspect they still don't have enough cash flow to sustain operations long term. They are steadily shrinking in developed countries.
