We don't need to register anything with the SEC since we can usually find an exemption to registration, but the SEC rules need to be followed.

Specifically, for me as an investor, if I were NOT licensed there are some smaller multis (2-3 units, the most common type we've got) that have exemptions for protected classes in certain cases, but as an agent you waive all exemptions.Obviously this isn't a big concern, but I've seen it trip people up and it's a hassle if you forget.Good luck!
