Printing pubs costs money. Think about it. They can't possibly be making enough to cover production costs, even with the slave labour. The org is worth billions.
While this may at times cause liquidity issues, they surely are in a position to keep themselves afloat for a long time to come. They can buy and sell rel estate all they like, and do it tax free. We can't expect them to be fading off the scene because of money problems anytime soon. All they have to do is get some COs to suggest some congs' KHs are getting too old. A new property is purchased with money borrowed from the org, the debt is paid by that cong and neighbouring congs. The old hall is then sold off and proceeds go to the nearest branch.
If the hall is an older one and the title is still held by the local elder body, the branch must seize ownership of the property. The CO suggests a renovation, at a cost that is estimated at what it would cost if contractors were hired to do the job. The cong votes to take a loan out from the branch for said cost, and the title is turned over to the branch for 'security'. The building is renovated using volunteer labour, the loan is repaid by the local Dubbies, and the branch owns the title.
Seems like a very nice business plan to me!
Anybody wanna start a cult with me?
