Wholesale taxes

[Mike Flora]

when doing a wholesale, either assigning or double escrow, we have the option to choose 3.3% of the sales price or 12.3% of your profit. I don't have an LLC and this is the state of California. Anyone have any other info on wholesaling taxes at close of escrow etc? And what percent should I store away for the federal capital gains tax?? Is it 15% or more of my gains on the federal side? Seems like it might be different since the deed never is transferred into my name.
