I think it is great to network and gauge interest for when a deal comes but bring them something before you take money because if you take the money first it is idle and they are getting no returns while it is sitting there unless you can pay some return out of pocket which I am sure you aren't doing because you are using OPM. 

Ultimately, it's about ensuring the property remains attractive to tenants and maintains its market value without pouring money into upgrades that won't pay off.

We could use it for 10 years and then would have to pay it back in the next 10 once that expires.

You are paying an intermediary for marketing and deal flow. 

when your dealing with a borrower with experience...its not wise to control the Construction, Its not smart to smudge HUD's (i took myself, title and attorney days to figure out my closing cost went from 25k to 40k)...later to find out most of it was in fees and paying 12 months in advance of mortgage payments.

Maybe because I've kind of run into this issue with paying people in the past.  

I see a lot of newer investors pay coaches tens of thousands of dollars, using debt, that stops them from actually investing!

If I went to a GC and said "Hey, take a look at this job and I will pay you" and they took the money, that is the red flag.

If a seller is offering $10k in assistance but the PP is only $189k on conventional a loan with only 3% contribution allowed, what are all the options for the for any of the left over contributions after. paying closings costs ?

How much % would you suggest paying him?
