It seems the responses kind of got lost in the weeds before giving a decent overview. Sometimes us attorneys do that. We just can't help ourselves. I'll try a very short one to the original poster.
When entering the world of trying to raise money from anyone (strangers & family alike), you MAY tread into securities law. Raising money can mean borrowing money from one or many investors, or selling "shares" or "equity" in any type of entity or project. There are FEDERAL securities regulations (think SEC) as well as STATE regulations & laws. STATES have their own securities departments or commissions. It is your duty to adhere to BOTH STATE & FEDERAL. The rules do not always mesh, depending on your state. However, the FEDERAL laws always apply, even if your state says something different. And sometimes the FEDERAL regs may be silent on a topic, but your STATE may have plenty to say about it. The Arkansas Securities Department has come down pretty hard on some real estate investors who raised (or tried to raise) $ from in state and out of state investors. They have also come down hard on out of state groups trying to raise money from investors in Arkansas.
All that being said, this is not the forum for specific legal advice. For that, you need to see a qualified securities attorney in YOUR STATE.
Hope this helps.
