Acquiring deals. How far is enough?

[Aaron Toliver]

So I've found three deals that I would like to bring to some partners. All three make 200+ after expenses and are above 10% cap rate. But here's the problem. The way a partner finances the deal could affect all those factors, right? I've just been penciling in 20% down at a 30 yr fixed as a default. 

Also, should I write a letter of intent with purchase options before I bring the deal to a potential Partner? Should I view the property before bringing the deal to a potential partner?
