LLC Partnership between relatives

[David Floyd]

I have a large property containing 4 duplexes that I need to split with my sister. I tried breaking off one duplex but the properties are located too close to each other and would violate setbacks and require a variance. So I’ve decided to create an LLC where I would be a 25% partner with my sister and she could by me out as in the future through monthly rents or when she inherits more property in the future. She cannot get a mortgage easily due to low income and credit. My plan would be to have her aggressively pay me off in two years or less. Does anyone have experience with such an arrangement and where would I go to set up this operating agreement?
