Form a Series LP or LLP. Cells with isolated liability.
Series LP and Series LLP are like Series LLCs: one master entity with multiple internal series (cells), each with isolated liability. Texas, Illinois, Ohio, and select other states allow series partnership structures. Best for real estate investors and investment funds wanting multiple isolated entities without forming each one separately. Cheaper than separate entities; jurisdictionally less tested.

Master partnership formation
Form master LP or LLP per state law. Partnership agreement specifies series creation mechanics, series management, distributions per series, isolated liability.
Series creation
Each series created internally per the partnership agreement. No additional state filing per series (the cost-saving benefit). Each series tracked separately for accounting and liability purposes.
Per-series operations
Each series has its own bank account, accounting books, and (if needed) EIN. Operations must maintain series separateness or risk losing isolated liability protection.
