That must be so frustrating from your side of things, as the owner.

Me as a tenant. I wouldn't tell the RE we were looking to move until I had been approved for another place. I know it must seem inconsiderate to the owner but if we don't find something but still have other people invading our home while the RE is looking for new tenants before we have even given notice.. No thanks.

Bugger about the tradie & the roof! How rude!
