Partnership question finance vs free time

[Travis Elwood]

A friend and I are working on purchasing a duplex and want to set up a partnership to do so. I am currently making roughly 2x his income and he cannot financially cover what would be fair in my eyes 50% of the expenses to get the project up and running. I have less free time than him and he points to that as his value add. We plan on property management, and outsourcing most of the labor as well. I am finding it hard to front 20k into a deal where we are near equals in partnership, in my eyes the value add isn't there for that contribution on my end. I am trying to find compromises we can work out so I don't feel like I'm funding his early retirement as opposed to simply finding a deal and funding it on my own. How much of an asset do you think his free time is in comparison? He has helped acquire a very good real estate agent and for that I am very grateful the deal is off the MLS after that I'm struggling to see the value. How can we structure the deal so we both win?
