The pics were basic cell phone pics.

If you have a large nest egg then yes I would get an LLC.

One solution to "chicken or egg" puzzles is always to build both a chicken and an egg at the exact same moment, simultaneously. 

@Reed A.Do you want to setup an account for just the master LLC or do you need to open accounts for one or more cells right off the bat?

My husband and I are reading "The Book on Rental Property Investing..." and are super excited to start building a huge nest egg so we can retire early and travel.

Based on what I've learned so far, wholesaling seems to be my first option to begin building an investing egg.  

In my mind buying a rental with all your liquidity is not something you should do unless you have a concrete plan to scale. you would be better off in the long term buying some sort of business or finding someone to back that is into short term quick profit deals and keep building your nest egg

Show her that you'll contain the risk and not put all the eggs in one basket.

Don't put all your eggs in one basket.

Seems as though it's a bit of a chicken and egg problem.
