Everyone is busy. It’s likely the case that landlords have other work commitments, and demands on their time. A tenant who expects an owner to be at their beck and call for every issue, no matter how small, will create a frazzled relationship that induces a sigh every time the landlord receives a phone call.
By the same token, if your rental property’s hot water system is broken and you don’t attempt to fix it the same day, that’s not showing much respect for your tenant.
Indeed, a landlord could be in breach of the contract, as they have a duty of care to provide hospitable accommodation (including clean, running hot water).
Property Manager: Will source the right contractors and arrange quotes for the landlord. They will also arrange for tradespeople to attend to the repairs/maintenance and keep the landlord and tenant informed of the proceedings and costs.
