One guy was talking big game, but he only did one duplex.I’m trying to find a workable model to scale up, but haven’t seen the light yet. 

That way he won't have as many refinance issues.There was a podcast not too long ago where they talked about a HML that doubled the interest rate after 6 months or 12 months or something ... just something to think about to light the fire (and make a little more for you in the deal, if it comes down to it).

Burnt out lightbulb, toilet flapper not seating, worn agitator dogs, bad ballast in fluorescent lights, faulty circuit breaker, leaking wax ring in commode, loose p-trap cap connecters under sink, modem has reset to factory default, thermocouple needs replaced on hot water tank, filters need replaced for central heat/air, ceiling fan needs balanced, lint trap on dryer is torn, source input needs reprogrammed on HDTV remove, headboards too close to wall and making impact damage. 

I absolutely love the points that @Henry Lazerow brought up.Totally my opinion, but if you can finance using either of these products and do a decent size rehab you will be light years ahead of most. 

I work in the power industry for the largest clean energy company.

Already stated by @Eric Yu in an excellent way.I just recently turned 30 and I can say with absolute certainty that if my light bulb moment came at 22, I would house-hack without question.

Based on a video walkthrough, the property needs new paint throughout the house, new carpets in all the 3 rooms, new kitchen countertop, new light fixtures and i plan on resurfacing the popcorn ceiling. 

If you decide to put more cash into it, make sure you don't overspend as sometimes the neighborhood's average price/condition/demographics doesn't look good for a brand new gutted property with marble floors and European light fixtures.
