Selling your home is a very important decision. You should always choose a Realtor who you feel you can trust.
I think the easiest and the first thing you should do before hiring any realtor is search the California Department of Real Estate public information website using agent's name (or license #) and see if his/her real estate license is in good standing. If all the information seems to be Ok, you should go further and do a little more research using other sources.

I hope it all works out for you for the best :)
