Bill Gulley is right: This is not an easy subject, nor one that can be trivialized. The repercussions of getting it wrong are huge (not just trouble with the SEC, but your state securities regulator and also your investors, who have been known to sue when all of the risk factors of a deal were not disclosed to them and the deal turned bad).
Start with your state securities office. Ask to see some of the filings others have made for real estate. Many states have an intrastate exemption that is far easier to deal with than the restrictions on SEC private placements under Reg D, and let you advertise your offering to in-state investors. Intrastate exemptions are often available to non-accredited investors, while offerings under SEC Rule 506c are available only to millionaires (but you can advertise them...it's what all the crowdfunding sites are using).
Under rules 505 and 506c, however, you may include up to 35 non-accredited but "sophisticated" investors, but these two exemptions require audited financials and you can't advertise your offerings...you can only promote them to those with whom you have an established relationship. And sophisticated investors need to be people who understand real estate investment fundamentals and have business experience...people who "get it" when you talk to them about a real estate deal.
After you have developed a PRIVATE network of potential investors with whom you have established relationships, you can show them your "sample deal" one-on-one and ask if they would like to be notified when you have a deal that looks like it. But these folks should be accredited investors/millionaires, or, in the case of the intrastate exemption, state residents (and I would suggest, sophisticated investors you've met through REIAs, etc.). Make sure you are dealing with people who can afford to lose ALL of their investments; don't be thinking you're going to take a substantial portion of Grandma's life savings. Personally, I think it's dangerous for anyone to stick more than 5% of their assets into in any one deal.
Once you have a real deal signed, then you need a securities attorney or service to draw up your Private Placement Memorandum, Form D, operating agreement, and subscription agreement before you talk to potential investors about it. Personally, I'm going to use Reg D Resources, www.regdresources.com. They prepare everything for a 506c offering for $5500 (except the LLC operating agreement), about $4000 less than a local attorney wanted, and for a far better looking PPM. They've been doing this since 1999, and their documents meet the tougher Form 1A requirements for small public offerings (so they work great for state private placements). The only thing I am using a local attorney for is my LLC operating agreement, which shouldn't be one of those "stock" agreements you see online for free or $29. (Case could be made that one could "borrow" an LLC operating agreement from someone else's known deal on a crowdfunding site, then submit it and all the docs done by Reg D Resources to a securities attorney for approval as the last step, rather than the first.)
Be ever so careful! Don't discuss specifics of any real deal (such as rates of return) with anyone until you have filed Form D with your state securities office and the SEC and have your prospectus/PPM to show. Let your lawyer-approved documents do the talking, and don't deviate from those documents one iota when explaining the deal to investors (ideally, in person and in private after many previous meetings).
