Equity Partnership Question

[Daniel Murphy]

New investor here. My question relates to how to structure an equity partnership that is separate from our existing partnership income without opening a new taxable entity. For example, My LLC wants to do a deal with Company XYZ where they pay the down payment on a loan and we split the net income generated from the property 50/50. We already are generating income with our existing properties and we each own a third in our existing partnership. We would rather not split our current profits with Company XYZ that we are already generating and would want to separate this new deal from our existing portfolio. Is this even possible without filing an additional LLC? If so, how would it be done?

Thanks!
