Minimal Blue Blook Requirements for CP loan

[Brent Moonsammy]

Hey there BiggerPocketeers, 

I just made my first deal on a piece of land and plan on building a barndominium within the next few months. I will be needing a CP loan and the main requirement is the Blue Book. My Question is, What is  the bare minimum I can show my lender to be approved for my loan. The cost of the plans are dependent on the detail of plans. Which Plans can I afford to exclude. The location of the property is unincorporated. 

Note: I am a CAD technician for a survey company and will be able to create my own Site Plan and Survey.... if that helps me at all.
