From what I have seen here in Poland, they are not closing any halls or selling off any property. They are simply combining congregations with low attendance. In my case we had 2 congregations sharing the same hall with supposedly about 80 pubs each , but usual meeting attendance was about 50%. They said it looked bad for new ones coming to see only 40 people in the hall (not that any new ones ever came when I was there) and now it is more impressive to have a packed hall. It also helps with expenses (don't have to heat up the hall so many times per week for example). It is just reverse spin. Before , it was smaller cong's allow for more individualized help. Now, it is 'feel the love' of so many of JHVH's people in one place.
For me it was a good excuse to stop going - I can't handle being in a small room with so many people. So far, nobody has called me about it.
