Contract Assignment in California

[Nixon Vayupak]

Can anyone who wholesale in California please confirm if this correct or incorrect.  I was having a conversation with a broker and they informed me that by law in California you are able to assign contracts up to 8 times in a year if you are not a certified Broker or Real Estate agent here in CA.  If this is true what other routes are available if you would like to wholesale additional deals, besides double closing?
