It comes down to this. By issuing a work order, the OC is entering a contract.
I agree with all of that. In this case, if you can’t be sure you will have the funds to hand to pay by the payment date, then you should hold off until you are. The contractors will not be interested in you telling them you are chasing up a few backsliders who will, for instance, pay their levies when they’ve sold their flat.
You might even consider getting a line of credit from a strata loan provider – or even better, a strata loan – so you don’t have to worry about chasing bad debts while running up another one for the OC.
