@Jeffrey Allen, good questions and good advice here.
An SEC attorney can explain and advise you about the 506b or 506c structure of your investment offering or whether a JV structure is appropriate. Usually they also can form the LLC(s) which own the property. A syndication normally requires 2 or 3 LLCs which GPs and LPs separately own.
A separate issue you need to also ask for legal advice on is how do you own your % of each property. I am not an attorney, an accountant or a financial professional, but I recommend everyone get proper advice from professionals who themselves are real estate investors. A professional who does not invest in real estate themselves does not fully understand the issues that real estate investors face. This frequently causes bad advice even though well intentioned.
Asset protection is critical. Too many people, IMO, own property in their personal name instead of a corporate entity. This exposes two way liability risks. If there is an accident or incident at a property and you are sued, your other properties and personal assets are exposed. Likewise, if you or a child of yours is cited for a vehicle accident and you are sued, the plaintiff can go after all of your properties. Check with an asset protection attorney.
Good luck to you.
