First Time Developer - Equity Split Question

[BJ Smith]

I’m currently putting together my first real estate development deal. I presented a development idea to a friend/investor in real estate development. The deal includes purchasing land in a different state and building for Airbnb purposes. The idea was my own, I engaged him as I thought it would be a great idea for him (and his team) and now I’ve identified land. I would be responsible for overseeing the deal from beginning to end, including permitting, finding contractors, project management, marketing (I bring valuable influencer relationships to accelerate awareness and consideration), etc. I will also be charged with flying to and from the other state as needed, but will hire a local property mgmt company to oversee the property day to day.

I do not have any money to allocate to the project. They are putting up all $. The deal will cost anywhere btwn $400 to $650k. I am trying to determine what equity I should receive for my role in the deal?

There’s a chance I can actually purchase the land and then bring them onboard but am not sure how that would be organized as ice not shared this idea with them. The land is roughly $70k.

Looking for a bit of advice in terms of what I should be asking for in terms of equity % in addition to whether or not it would be in my best interest to Acquire the land first and if so how do I then factor that into the deal and what should my equity look like then?

Thank you for any insight and advice into how this should work as I’ll be Investing much of myself into this project!
