Only things I would add...Finished floor to ceiling height has to be at least 6'8" in a basement (your house looks newer so I'll assume it is)Minimum habitable room size is 70 sqft and at least 7' in either direction.

Overall I think it is a good gameplan.One other option you might consider to scale faster perhaps is to buy the 1st two as owner occupied. 

Now that the rehab is complete, there's some equity in the property, and I'm moving in, I can't help but wonder if it's smart to take this time to do something on the side to pay down my mortgage faster or start educating myself on screening tenants and doing my due diligence.

Getting alternate financing (wm2nd, heloc, etc) for equity position may be possible but it will 1) be at market rate 2) may increase the due on sale clause. 

Is there a faster way for me to scale?

With SFR, it will likely sell faster if you ends up being your exit strategy. 

I understand that this can sometimes lead to more wiring than was initially expected, so I need someone who is up for the challenge and at a price that's hard to beat!

Quote from @Renaldo Zora: Quote from @Travis Biziorek: Detroit has to be at the top of this list.I have 14-doors there (from California) and we're doing lots of deals, all-in, for $75k-$90k.12-months ago that range was $60k-$80k so I'm not sure how much longer we're going to be under the $100k mark but there's still a lot of opportunity.I just finished up a duplex in Detroit.

Hello,A good rule of thumb in NC I tell my sellers about: if we get lots of showings in the first 2-4 weeks, but no offers, the price is too high by a good bit (15-25% estimated).If we get showings, and one low ball offer, the price is a little too high (5-10% too high).The longer a property sits on the market, the more likely you'll end up accepting a lower price ...better to go ahead and do a price reduction now and sell it faster, than letting it sit and eventually the market will do the price cut for you. 

I switched to laminate vinyl plank and it can take a beating.
