@Mark Weinstein Is it impossible? No. It's completely possible to do all three. But there rises the need for focus and sequencing. Focus - the more you focus on one thing the more progress you're able to make rapidly. Sequencing - What order should you do these things in (with the goal of highest 'success')?
You can do all three, but do not start with all three. Start with one, focus on it, grow in it, and know it inside and out before taking on another thing to focus on because you will be diverting your focus from the initial goal. I recommend starting with Realtor and being an 'investor friendly realtor' to help other investors and by doing so, learning more about their process, how they evaluate deals, what their criteria are, etc. Offer to run rental and property value comps for them and you'll be their best friend. From there, work on your first BRRRR property. If the numbers work out well then rent it (this is what you should shoot for). If the numbers are not ideal, sell it and you've completed your first flip.
Hope this helps. Good luck.
