If you represented a buyer on a non-MLS sale, you could submit that listing after closing as a Sold Non-MLS listing.

1. Start in the Input page of Matrix. 
2. Click Add New (Listing).
3. Complete the Sold Non-MLS Input Form for the property type you are entering.

You must be the buyer agent to enter a Sold Non-MLS listing. When entering the buyer agent code, you will only be able to submit the listing using your own MLS ID. 

Listings should be entered promptly after closing, but the deadline to enter a Sold Non-MLS listing is January 31st of the following calendar year.
