1.5 million in debt isn’t a lot for a 70 unit block. You have 1% so your share is $15,000. They will probably be paying 9% interest, so there is likely a move to firstly get rid of the debt, so they aren’t paying interest, and there are probably other things that they want to do. It also is possible that some of the debt is due to strata arrears and that can take a while. You will need to take into account that there will be special levies.
