I actually hand wrote the contract on his kitchen table.  

Appreciation does not pay the bills or put food on the table.

The section on the left hand column of the table (starting with total annual income and ending with annualized total return) a formula for each would be very helpful.

I've done so much research and writing out excel tables and calculating, and now at the end of the year I plan on getting a second property when a deal comes along!  

If the tenants has an extra $200 available to give you she most likely 1) is hiding under the table income from SEC 8 or 2) hasn't an add'l income producer living with her who is not on the lease. 

What do you bring to the table, what value could you add to a partnership?

I get paid  under the table for my nanny job so it looks like I only have income for my weekend job.

I have a few deals on the table, nearly perfect credit, and $150 cash.

What if you could turn the tables on these guys once and for all?

If you are prepared to take that much risk with a partner I would say  take LUCK off the table and go for it.
