If you have a particular property that sold, you can ask the listing agent. Or if you want a more general idea, you could ask a Realtor to pullup the "Closed" listing in a particular area for a specific time and the Realor could do a search for you. There is not a public site that shows the selling agents.
If there is a particular home you are interested in finding out who sold, I can help you with this information. Otherwise I believe that the public view MLS does not provide that info...Thank you! 775-379-9617 or firstname.lastname@example.org
