There were also differences between the instructions on the bottles, vs the instructions on the website.  

We are having steel door with frame, lock etc locally manufactured and installed in a masonry doorway by the manufacturer for 1000 dollars each.

The neighbood ranges from 40 acre "ranches" to 1-2 acre lots with a mix of manufactured houses and 4000sqft custom houses.

Give instructions on what should be done by the tenants to retain their security deposit and/or avoid damage assessments; these include: removal of all personal items/trash, appliances/bathrooms emptied and cleaned - basically the unit is to be returned in the same condition as when they rented it (less normal wear and tear). 

After the applicant submits their application through Buildium, they are sent an email with further instructions on how to go to MySmartMove to complete the screening portion.

I have also found a great deal on a manufactured home w/ land that would provide excellent cashflow. 

Absolutely, take action on all the instructions they suggest to you. 

When dealing with a Realtor, go with their instructions as to what is customary in that area.Realize too, that earnest money deposits are funds held in trust and before the escrow agent can release funds back to a buyer on a contract they can require the seller to sign a release, as it's funds held in trust for their benefit, again, local custom and state requirements.

The house is right around the barns, grain bins, etc. and the 2 sides of the yard are directly adjacent to planted crop fields during growing season.Is it realistic to accomplish this sort of respectful use with clear instructions or intake orientation process?

Check the Secretary of State website and they probably have forms and instructions for creating it on your own.
