I’m with you on this but I doubt the incentives are there for the agents to chase up the owner / strata company for these plans.

Have you tried searching for the same address in the buy section of realestate.com.au? There are a lot of properties that have recently sold that still have images from when it was sold which includes a floor plan.

I’d recommend the free edition of Remote Desktop Manager by Devolutions. It’s way more features than your current use case so it definitely as the room to grow if you want to expand the connection types you are using.

It will do connection and credential management, our primary use is for RDP but also use it for web sessions and SSH.
