If the mechanicals of the home (plumbing, electrical, roof, and HVAC) are all centralized to a single unit, I think your home inspector stands a much better chance of spotting an issue as opposed to a multi-unit with multiple independent systems that may or may not be accessible due to tenants.As for closing costs, try to push the closing date until you have the funds available?

4- Who maintains control of items purchased for the above work, the Management company/Landlord or the Make Ready/Rehab contractor?

What I don't like about the property:Location (possibly, but that's why I'm coming to everyone on the forum for advice)Possible costly repairs to fix the upstairs units, the bones look good from the pictures but I understand that it would need an inspection from a professional to assess things like the roof, electrical, plumbing, etc. 

I have a friend who is a contractor my property is in Kansas City and we are in California I have family also in Kansas City.

I learned that you cannot trust every contractor you meet, and that patience is a virtue in the real estate industry.

Ask your realtor, friends, contractors etc for property management recommendations if you go that route.
