Does anyone have experience building waterfall real estate models? 

I'm putting together a deal that includes a preferred return and split. It's a simple structure - 8 preferred, 75/25 split. 

However before I circulate to my partner, I want to reach out to see if seasoned eyes could look over it to make sure I wasn't missing anything. 

If you have experience with waterfalls and wouldn't mind looking over what I put together, I would appreciate it.
