The timing of repairs needs to be determined according to factors such as risk of personal injury, risk of damage to property, level of inconvenience and funding available, etc. If there was significant risk of personal injury, for example, the repairs should be treated with the utmost urgency and all stops removed to make happen (including an urgent special levy and borrowing if a levy is not possible).
If the problem is only causing inconvenience only, then the repairs should be slotted into the repairs and maintenance programme according to priorities against other works and funding availability.
The sale of one’s apartment in itself should not be a factor in determining the timing of works. Perhaps the Lot Owner might consider timing the sale around the repairs and maintenance schedule rather than the other way around. However, the OC does need to be able demonstrate that it is competently managing all repairs along the lines that I have outlined above.
