For good measure, the new investor could put in $10,000 of their own capital to show that they are going in with what they can reasonably afford, so that they have meaningful skin in the game as well. 

The borrowers had no skin in the game and many ended up being crooks and setting up fraudulent deals.

If there was room to earn more 'skin in the game' by any other time, strategy, or management aspects, I'd be up for that too, but just the learning experience of seeing a small multi build through to completion would be amazing as I plan to do exactly that with my own somewhat conservatively leveraged capital down the road. 

Edgardo,I'm not clear if you are buying these properties yourself and putting skin in the game OR are you working with investors to provide information and then acting as their agent to sell the properties?

Lenders want to know you have "skin in the game" in other words you are investing Your money not money given to you or borrowed. 

They will, however, expect you to have more skin in the game (i.e. more of your own money) and may charge higher rates and points to mitigate their risk. 

It didn't quite hit me until you mentioned when I refinanced, I would have a lower skin in the game which would drive the COC-ROI percent up as well.

Many good suggestions above -- there are many ways to skin a cat in the REI world. 

But both parties need to keep skin in the game. 

You gotta have skin in the game or nobody is going to deal with you
