question to investors I have relationships with this early in my career, or to stick to my conventional Househack until I have a “history”?

Why would they give you their hard-earned money? 

In my younger days I leaned towards buying homes that were easy rental converts, that was a great wealth building strategy and I ended up doing it a few times over, but a lot of that was possible because my primary career and incomes kept growing fast.

C-class building that has a laundry facility that earns some income.

I know this can be a lucrative option for sure which is why I’d love to start this way so I can take my earnings and invest into other and into rentals possibly.

@Bob OkenwaBob is correct.Especially if you plan on making this a career... mortgage fraud will crush your dreams.A lender calling a loan due in full when they find out you don't occupy a residence you said you would, or when they see your rental posted when you said it was a primary or secondary home is minor compared to mortgage fraud.I once worked for a mortgage lender who has a friend who was convicted of mortgage fraud.

Don't get me wrong, I am extremely grateful for the job, blessed to have it, but I don't see it as a lifelong career, I don't think I ever have seen it that way.
