Nonjwspouse, that is exactly what happened to a congregation in Australia. It was just over a year ago. They were told they needed a bigger hall because it couldn't hold all the people attending the Memorial.
This was in an area that had low JW numbers originally because it was in a quiet area. It wasn't until about 20 years ago that they had enough members able to put the money together to build their own hall. Prior to that they were renting an old hall owned by another religion. It had no heating or air conditioning, no carpeting and hard wooden benches.
The hall was built in a very desireable location and sold for a lot of money, there would have been more than enough to build a hall twice the size on another plot of land in the area.
Now the members have to travel 20kms further and attend meetings at a more unsuitable time to fit in with the other congregations using the same hall.
Not everyone agreed to the sale, I know of at least one person that voted against it. It just didn't make sense.
