We had a revolving 0, giant goose egg, and we were both savers but had one of those nice A frame relationships where weird things happen as the top of the A crumbles... 

Get rid of unnecessary expenses like cell phones and cable TV.

Always open to more but don't want to lay too many eggs in one basket.2. 

Get a small nest egg built up and you can get into a house hack with an FHA loan with 3.5% down.You can do it, just got to hustle!

Might be too risky for my first investment, unless an off market deal pops up as a golden egg, as suggested by @Dan Bernstein.

My objective is to build a nest egg that I won't touch for 20 years or so, and I have a pretty small appetite for risk in this portfolio. 

That way, you can start getting used to some of the ways your cell phone might lie to you.Good luck to you!

This is not meant to be biased, but you will find it surprisingly hard to discuss fine project details and give important direction over cell phone with someone whose English is not good.

I'm hoping I can save up a nest egg in the next couple years so that I can just operate with cash.

But if you sell your property now and just park your money, you will not see very good returns in any investment vehicle that is liquid and safe.You have a hold of a "golden goose" that will keep laying cash flow eggs and appreciation eggs for a long time.
