Yes, the BOE 2014 March 29th specifically said: "The need for Kingdom Halls and Assembly Halls is greater than ever before. At this time, over 13,000 Kingdom Hall projects and 35 Assembly Hall projects are needed worldwide. Much of this need is in parts of the world where the cost of property and building materials is high."
This is the beauty of this move. Selling property serves three goals:
(i) most obviously, they get access to liquid assets, but I think this is the least important bit
More importantly it serves the main goal: create a shortage of kingdom halls. The benefits are twofold:
(ii) it create an obvious sense the WT is expanding: The number of kingdom halls are too few, too crowded and many halls must be build to serve a growing need (see the letter).
(iii) secondly, to build new ones there is an obvious need for money. Everyone can understand this need and see imediate benefits (ones own kingdom hall near the home) and thus the WT can push for donations.
There is NO reason to think this means the WT is financially pressed. This is the obvious strategy to follow if you are in a situation of little or zero growth.
