That's a great idea...no excuses now
Out of curiousity, how many plumbers/electricians will come when a tenant calls..and then wait for payment from the landlord, without the work being authorized by the owner?
How many tenants are willing to pay upfront for a repairman?
The tenant will pay for it (up to the value of two weeks' rent) and ask for it back from the PM or landlord according to the RTA link I posted...
"If the lessor/agent/manager or the nominated repairer cannot be contacted, the tenant can arrange a suitably qualified person to carry out the repair. The tenant can pay the repairer themselves and get the money back from the lessor/agent/manager or get the repairer to bill the lessor/agent/manager. They should forward all receipts to the lessor/agent/manager who must pay them back within 7 days."
