OneHome allows a client to work with multiple agents, all under one account (rather than creating separate accounts for the client to work with each agent).  It will only display the information provided from one selected agent at a time though.  If your client is working with another agent - for example, if they are working with you to purchase a home in North Carolina, but working with an agent in another state to list their current home - your client will need to switch from this other agent to you to see the information you have provided to them.

For your client to do this they will log into their OneHome account, then click their profile button at the top right of the page (the circle with their initials in it).  Here, they will click "Manage Account".  On the next screen, select "Agent Preferences" from the menu on the left, then click "Edit" in the "Your Agent" area.  This will display a drop-down menu of all agents that your client is working with (or has worked with before).  They'll select your name here, then click "Save".  Once done, OneHome will keep your information on display for them unless or until they change this again.
