KEY: you must hire a "qualified intermediary" BEFORE you sell your current property.For more details, talk to one of the intermediaries, @Dave Foster.

@Dave Foster

You want an unconditional obligation to pay a fixed or determinable sum in the future.Also any related party transaction is subject to greater scrutiny due to there being a potential lack of adverse interests, but instead possible collaboration the undermines arms-length principles.Arms-length = economic adversaries.

or collaborate.  

This could entail the owner, architect, and construction staff all collaborating to develop a solution.

maybe we can collaborate on a small multifamily in your area.

I would ask @Dave Foster and ditch your current QI (tongue and cheek).

Quote from @Dave Foster: @Kat Hughes, Been noodling this since we talked. 

Sell ownership of the land (if left undeveloped) .77 acres owned by my LLC and collaborate with a builder on just the interior design of homes by having some creative control within the budget of the builder (just for fun/ experience to have my LLC listed in part for some design listed credit) and receive a set fee per home sold. 

A few months back, my son, a talented software engineer, and I, a real estate broker and investor, embarked on a collaborative journey.
