The only snowball I'd worked on was toward a career where I'd get more and more work, less and less time, and always thinking "I'll be happy after the next promotion/raise/etc."

Maintain the property and begin implementing strategies that promote tenant retention before you need it.Buy in Fundamentally Strong MarketsThe temptation is to chase yield in speculative areas without a strong local economy, but don’t fall for it!

I agree with @Scott Harper, I used to live in Florida and was a member of the CFRI group - you can meet some good folks there, but they do heavily promote gurus and classes - so just skip all that and listen, learn and utilize Bigger Pockets - with none of the Hype!

I'm confused about the part of this being a value-add commercial building (and a fairly big one, at that) being promoted/sold by a turnkey company.

Promote yourself as a LICENSED agent first. 

So right now I'm studying for my next promotion board, so all that extra is going towards RE.

Cross-promotion.
