A bunch of finishes to make it look pretty (drywall, paint, floor tile, cabinets, countertops, light fixtures, backsplash, sinks, faucets, bathtubs, etc)Not much else to it. 

This super cute house has new roof, new plumbing, electrical system, interior/exterior painted, double pane windows, ceiling fans throughout, new doors, new kitchen cabinets, new light fixtures, wood floors, granite kitchen countertops, new stove, exhaust and back splash.

I bought this with private money entirely, including 20k budgeted for light renovations.

My goal is definitely cashflow early on, but i want to use that "energy" as David Greene says, to invest into multi-family properties and possibly medium-term down the road.

I have owned a number over the years, and am closing on a 5 unit within the next two weeks, so I may be able to shed some light if we iron out some details related to your deal. 

They placed tenants really fast - almost right when the light 6 week rehab ended.

They usually are more energy efficient than baseboard heaters but are a shorter-term solution. 

You may be the first person they've spoken to in months that will have approached them in a positive light. 

You're asking someone to spend a lot of time and energy to share what they've spent years - maybe decades - learning and developing.

Core strips food/energy and is more closed followed.
