It's so beyond what my pre-investing brain can comprehend that doing another $20m loan for a $30m property feels 'meh'tldr:  Don't let it bug you if your goal is to have a large portfolio.  

So I’m in a bit of a bind, I have a duplex I’m house hacking we remodeled entire thing, new hvac, electric panels, electric main, updated plumbing, water heaters, furnace, install central air, roof.

To me this certainly includes;  plumbing and electrical.   

I have redone the foundation, all new electric, all new plumbing (PVC to the street), all new kitchen, added a bath, new flooring, all new windows/doors, updated all insulated while walls were open for electrical, new furnace/AC, new siding.

I would probably choose to do the electrical plumbing first.

The house is about 70% complete but still needs electrical, plumbing, and AC brought up to code and the finish out to be completed.

Electrical or plumbing need moved? 

@Brett JurgensSolar on my house would be around $40k and my electric bill is not even 200.

That renovation included everything inside the exterior studs (all-new heating, electric, plumbing) and exterior siding.
