Two practical considerations are worth keeping in mind.
Your investment needs to be fundable
Alternative assets have their own minimums. A private placement may require a $25,000 minimum investment. A real estate purchase requires enough capital to cover the purchase price, or at least the down payment if you are using a non-recourse loan, plus carrying costs and reserves. Cryptocurrency and private lending can be started with smaller amounts.
Before funding your plan, have a general sense of what you intend to invest in. Your target asset class should drive how much you fund at the outset, not the other way around.
Bank minimum balance requirements
Your Checkbook IRA or Solo 401(k) will maintain a checking account in the name of your LLC or trust. Our partner bank has no minimum balance requirement for self-directed checking accounts. If you choose your own bank, be sure to inquire about their policy.
You can start small and add funds later
If you are not ready to fully fund your plan from the start, that is fine. You can fund minimally at first and roll over or transfer additional funds once you have a specific investment under contract.
A common example: you know you want to purchase a rental property, but you have not identified the right one yet. Fund your plan with enough to cover an earnest money deposit and pre-closing costs like inspections, then take your time finding the right deal. When you are under contract, transfer the remaining funds needed to close. This keeps your capital at work in your existing accounts while your plan stays ready to act.
