Trust deeds - California

[Vani Sood]

Hi, I am new to US/ California real estate investment scene. As a resident of California, I am looking to potentially invest in trust deeds. I would really appreciate if someone could shed light on the following:

1. Does California law stipulate an investor to be an "accredited investors" to be able to invest in any trust deeds and crowdfunding investments
2. Does a residents of California need to be accredited investors for "out of state" trust deed investments and crowdfunding investments opportunities?
3. Are there any legal regulations in California on the maximum interest that can be earned by private money lenders (referencing to usury laws in California)?

Thanks in advance.
