You need to contact MLS and subscribe. Mlspin.com
Or you could do an entry only listing with a Realtor that is already subscribed.
Where is your home? New listings are exciting!
You will spend more time getting up to speed on forms, required/suggested procedures, dangers, etc., and then showing, advertising, following up on clients, when these are already in place for a good pro. If you think you can bill yourself out for the same $/hour as your own broker, check your math.
Plus, they'll probably refer you their clients for closings and other legal work over the long run as a return, which could help you build your legal business over the long run.
"Penny wise, pound foolish."
Since you are a Broker, you don't need to hang your license with a Broker. You will need to contact your local Board of Realtors and join to gain access to the MLS for your Brokerage. If you just want to get your house on the MLS (and don't want to join your local Board), you could list with another Realtor.
