We also have around $12k in student loans left (down from $101k) that I’m putting every single penny towards paying off by June.  

I am looking for good sub-contractors/referrals for cleaning, coating wood floors/carpeting, and interior painting. 

Its penny wise and dollar foolish .  

(5-7k to place entire stack)Your water lines are they copper, cpvc, pex?

definitely want to know their criteria as @Nick Hedberg mentioned, depending on their investment strategy will determine how deep of a discount they are looking for and type of property, some investors actually buy at market rate betting on appreciation others want pennies on the dollar.

That's why my PM is worth every penny.

Fixit persona and start spouting crap about electrical, plumbing, HVAC, plastering, things that it's painfully obvious they know nothing about: "All you have to do is skim-coat that, just stick those tiles right back on..."

Perhaps I didn't want to hear that I couldn't afford to do this project.Mistake 2: I probably overpaid a bit for the property out of the gate considering it's condition (vacant for 4 years, copper boiler pipes cut out, kitchens and baths complete disaster, etc).

Your "fair share" is paying what you owe legally and not a penny more. 

Heating pex is highly restrictive per foot for flow compared to copper or black iron.
