Since this particular lender isnt requiring ground up construction experience, based on our conversation,  I will have land purchased, drawings, construction documents for permits, and surveys complete at that time.  

Get survey to split the land.

In a Polaris Project survey, 64% of trafficking survivors said they were homeless or had unstable housing when they were recruited.

Off MLS they probably could have gotten a survey, title insurance, and some HOA transfer fees when purchasing, so better deals off MLS, and with no restrictions for resale.   

I would need to have drawings created and a new survey taken.

You know big trophy ranch's and I have to think buyers that are buying 5 to 50 million dollar ranch's will not have a problem with a buyer broker arrangement It takes a ton of time and effort to sell those bad boys and its for sure a specialty niche.. you have to know a lot about Old western land laws  Water rights Timber rights Mineral rights you have to be very good with surveys and how to read USGS quad maps ( although google earth helps a lot) U have to understand hunting and fishing regs etc etc. .

Who cares if the response rate for the surveys has dropped from 70% to 40%?

You'll more that likely have to do a Topographic Survey and apply for a Floodplain Permit. 

From 3D printing of building materials to the use of drones for site surveys, the possibilities are endless.

And the bank should be requesting that survey directly from title.
