After reading that letter, I would say that buying in now has a significant risk of being hit with either "substantial increases" in the reserve fee (part of the MF) or special assessment(s) to cover the the upcoming work, especially considering this line from the letter:
"As we have an ageing property portfolio you can understand that projected work over the next 20 years is substantial and costly. To be able to commit to this programme will inevitably require substantial increases in the reserves funding element of our annual fees."
Combined with the exchange rate risk, I would be very cautious about purchasing a week there right now. It may be a bargain now, but could become a nightmare later. For those who have been around a while, this could be another South Africa TS situation.
