I am working my way to take the jump into my first investment. I am very determined, but spending some time to craft a plan to help ensure a hopefully smooth ride into this new frontier. 

I am moving out of my apartment and back in with my parents and transferring to be an remote employee so I can save faster and 100% of my income. Then the plan is to do an FHA loan and house hack a triplex. By the following year I should be able to save 30,000-40,000$. and I'll be ready to get my second property. Though here is where I have some options. Should I...

1) Continue to house hack the new properties and just scale up once a year that way, or are there limitations to the FHA loans to prevent this?

2) Or should I do a BRRRR, on a rundown fourplex? but if i go that route, i was wondering what kind of financing would be preferable in that situation. Could I still get the FHA for a BRRRR and house hack it? I know some conventional lenders may have issues loaning on a place that needs some rehabbing. And also with the BRRRR method, does the rehab budget have to come out of pocket? Also what's the best route for refinancing? Will it be a problem to go through banks who are judging me off my DTI, Credit score, and W2 job? is Hard money preferable?

Thanks for helping out with this as i continue learning, I just figured out the BRRRR method may help me scale double time, but there are many more moving parts that a new investor could mess up, luckily I am a planner to the bitter end, so lets get this going! Thanks guys.
