Welcome to BiggerPockets, AK! All

The mortgage would be about $2300/month, however the 2 other units would provide right at about $2300/month in income...aka live for free!

The best feature is that the rate remains fixed for the term of the draw - most all of the other HELOC's I've seen have a variable or initial fixed, then variable.This HELOC is offered in the following states: AK, AL, AR, AZ, CA, CT, DC, FL, GA, IA, ID, IL, IN, KS, LA, MA, ME, MI, MO, MS, MT, NC, ND, NE, NE, NJ, NM, NV, OH, OK, OR, PA, RI, SD, VA, VT, WA, WI, WYThe rates are high, however if you are using this for a fix/flip or BRRRR, it's potentially a good product to jump into real estate and then refinance out of it later.

If the intention is to house hack, aka live in one unit and rent out the other units, then a FHA loan maybe an option.The cash flow is what I would look at and if the mortgage, taxes, insurance, and other expenses can be covered by the income.

Take the total $ volume of your transactions then determine the costs for joining a traditional broker vs a Kale type brokerage vs becoming a managing broker yourself.  

So, don't spend the money from the exit until you have it... aka live below your means and everything on top will be gravy.Also, if you have $500k in cash now, I wouldn't worry about staggering the investments.

I am looking to "house hack" aka live-in rehab in a home I am currently in the works of obtaining through seller financing, since it is non-FHA compatible at this point. 

Condos are also easier to own and easier to build some great equity with comparatively simple cosmetic updates (aka live-in house hack).
