I use to  give estate planning seminars with an attorney and stock broker, so I know it's not that big of a deal.

And don’t skip the due diligence—inspect everything and plan for unexpected costs.Take it one step at a time, and you’ll do great.

We plan to scale to 20-30 properties by end of year and was wondering if there's a better platform out there. 

I also have some cash reserves that I plan to dump into a contingency fund for each unit. 

My plan is to add 2 - 6 shipping container type of small houses and an above ground pool at some point to make at least a section of the property short/mid term rentals.

I have a similar project in Buffalo NY, however, I had to change plans when I got further into regulations.  

You Can Only Have 35 Non-Accredited InvestorsRule 506(b) allows an unlimited number of accredited investors but restricts you to only 35 non-accredited investors.However, there’s a catch:Non-accredited investors must be financially sophisticated.They must have enough experience to evaluate the investment risks.From the SEC:“Securities may not be sold to more than 35 non-accredited investors… [who] must meet the legal standard of having sufficient knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of the prospective investment.”If you’re planning to include non-accredited investors, make sure they qualify—or you could be violating SEC rules.3.

With patience and a solid plan, you’ll be on your way to building a successful portfolio.Good luck!
