I can confirm the OP scenario happening across the pond here in the UK.
A nearby old hall had two congs. The hall paid for and sat empty awaiting sale.
One cong dissolved and the funds it had been saving for a replacement hall (£100K) taken by - err donated to - the London branch.
The remaining congregation got sent to another hall and its savings funds (£125K) went to the London branch AND IT HAD TO MAINTAIN ITS OLD HALL until it was sold for over £350,000.
So that's over a half a million pounds of hard saved money/property gone over a couple of years to the FAT CATS in London.
