(I have about 3k liquid cash, and a 10k Roth IRA, no debts, monthly expense to income ratio of ~.31)I can either go the slow route, get a W2 job, get some decent W2 income, save as much as possible and continue learning for the next year before 'starting' or, I can seek private lenders to accelerate this plan.  

Of course this won’t continue and once I have repairs and vacancy that average yearly return will average down.

Welcome and much continued success!

Seems to be difficult to do this and I can understand why, the loan would be for about 27K, the current rate is 6.7%, is this a good rate right now, should I just keep it and continue paying it down?

I see house hacking as a way to continue to build my capital, allowing myself to purchase a second property faster.

In your shoes, if I didn't have rent on June 1 as scheduled, I would have posted a pay or quit and, if the tenant continued to not pay, done an eviction. 

Since that time it's tremendously appreciated in its value and now I am thinking if I should sell it or continue renting it out perhaps for another year or so.

Continue with the education, but I would also say to look into local investor meetings.. the members will likely be happy to help you with some documents they have used locally in deals and a bit of guidance.

I would also continue to search and compare software on Google to see what your best option is before settling on QuickBooks.

I've been able to continue making purchases only through private, off-market deals.
