Alabama-An Alabama investor must have either (i) a minimum net worth of at least $350,000 (excluding the value of an investor's home, furnishings and automobiles), or (ii) a minimum net worth of at least $100,000 (excluding the value of an investor's home, furnishings and automobiles) and a minimum annual gross income of at least $100,000. In addition, an Alabama investor's total investment in us and other non-traded direct participation programs shall not exceed 10% of such investor's liquid net worth at the time of investment.
