RealtyMogul (or similar) vs. Buy & Hold for Multifamily

[Ginger Zumaeta]

I'm a noob, but also an accredited investor. I'm wanting to get into real estate investing, and wondering about the pros and cons of private placements via RealtyMogul (or similar) versus buying directly.

Ideally, I'd like to be as passive as possible, but trying to weigh that with the returns of purchasing directly. 

For example, one possible investment on RM targets a 17.2% IRR and 7.2% cash on cash -- which is higher than I'm seeing where I'm currently looking (San Antonio).

On the surface, the RM option seems so much easier. Am I missing something?
