Just remember that all these contracts have to be approved at the first AGM of the Owners Corporation – that's you and other owners – so now is the time to see if there's been any feather-bedding, before they are all rubber stamped.
For instance, in the past some lift installers have sold lifts into buildings at a cut price to developers in exchange for inflated long-term maintenance contracts which get blithely approved at the initial AGM (because nobody wants to get stuck in a lift).
Ask for a copy of all proposed contracts, get together with a few other owners if need be to share the costs, and get a strata lawyer to go through them before the AGM. Anything that doesn't add up, reject.
