The only way to sync automatically agents and users properties is if they register in front end and the option to create agent profile on registration is set to yes.
Other workaround – update to 3.0 and in each property you can manually assign to user as well. So you can create manually an agent post, and assign to AGENT RESPONSIBLE. This shows in AGent Profile – my Properties.
You can assign the post to a registered user – and the user sees in My Properties – User Dashboard.
