Paying for training from the plan
I want to expand real estate holdings in my Solo 401k to another sector, but that would require me to take a 3-day course with a mentor to teach me the business model. Can I use the funds from my plan to pay for this class?
No, a training course in investing or travelling for the purpose of investing are personal expenses. These must be paid by you personally. You cannot pay these expenses from the Solo 401k.
Solo 401k funds can only be used for expenses directly related to the investments owned by the Solo 401k.
