Your $100K is low. I did some research awhile back, the Halls I could find records for on line were valued at 200-400K. I estimated that their holdings in Kingdom Halls alone are worth one to two billion dollars.
They've sold a ton of real estate in NYC over the last few years, producing something close to a billion dollars. Properly invested that alone should produce about four million dollars a month in income.
As noted above, their expenses are minimal. I can't see why they would have a cash flow problem.
