What is the Foundation of a Truly Great Partnership?

[Nikolas Hamon]

I have just finished reading the book "How to Invest in Real Estate" by Joshua Dorkin and Brandon Turner. Hands down it was an amazing read and provided a sincere education in regards to connecting with the average reader. One of the many things that caught my attention was the prospect of forming partnerships to not only finance a deal, but to educate yourself more and expand your network! As someone who is merely beginning their journey in the world of real estate, I am curious, for someone who has experience, what do you believe are the foundations of a great partnership, and what is the best way to structure them?
