I am in the process of setting up a Solo 401K. The plan is to have a Third Party Administrator (TPA) customize a plan which will be held at Schwab. Here are the features that I would like included so far: 1. Brokerage option 2. Roth option 3. Accepts incoming rollovers 4. In plan Roth conversions 5. Loan option 6. Non-traditional investment option 7. Allows for NON-Roth after tax contributions 8. Allows for non-hardship in service withdrawal of after tax contributions. Am I missing anything?
