Defianttruth, what you've said is the heart of the problem with being "real estate rich and cash poor." Equity is one half of the issue, the banks also want to know how you're going to pay them back. Equity is useful to them only if they have to take the building back when you can't pay the mortgage. In a commercial or multi-family deal the bank looks at the building's income stream from rents. In the case of WTBS properties there are no rents, and banks regard donations as unreliable. I'm under the impression the Watchtower has sold most of its NY properties, if there is some left, selling it is the only real hope of getting cash.
Orphancrow, in a word. YES. I recall Ray Franz mentioning this in one of his books, I can't find the reference just now. There's nothing wrong with it, and in an empire as big as the Watchtower's it's easier to find a way to move money around at places and times that yield financial advantages. Again, due to lack of transparency, we have no idea how much the WTBS makes doing this.
