It is able to do that smoothly.

We are currently transitioning from using our own cash to using private money.

That will leave you with a $60,000 profit if the deal goes smoothly.

Normally they will already know each other, so you only need to find one of the 3 to get started as all agents, attorneys and lenders prefer working with the same people to make a smooth client experience. 

I'm unsure how to smoothly mention these things though and leverage these advantages.Any advice?

Like building a house on shifting sand.But, if you can transition to a profitable long term- then no issues.

Your project will probably flow more smoothly if you purchase the land so there is no debt on it, and then finance the new build. 

A great ROI for a rough neighborhood is assuming things go smoothly, ie low vacancy rate, consistent rent collection, and normal maintenance/repairs. 

I find it easier to lump the operational funds together, it helps smooth out cash flow when I have a major repair or vacancy - the other properties carry the one with negative cash flow.

In terms of structuring, an issue that has come up is how do we handle the transition from holding one property to holding several, especially if the members of this business have varying levels of capital to contribute at different times.
