As you've probably gleaned, there's no real right or wrong answer here, particularly when you're talking about a few hundred bucks (30k, we'd all be urging you to save your $$). Personally, I gained a lot when I was brand new by attending a day-long workshop and then a 5-day boot camp that were each reasonably priced. I learned terminology, the basics of evaluating repairs, the basics of working with contractors, what desktop underwriting is and how to qualify buyers, an overview on marketing for leads, a crash course on land trusts, etc etc. I'm glad I did it and feel it helped condense my learning time on those basics. We declined the upsell to more expensive coaching classes and training, and I'm glad we declined those. The basics got us started, and then we jumped in, got experience, read books and found BP.
How soon is that class? Here's a suggestion: take your bullet points and do a keyword search on BP for each of them; then listen to every Bigger Pockets podcast on wholesaling, and decide at that point whether to sign up for the class.
