Below are USDA guidelines re: pole barns or other income producing buildings.
 Income-Producing Buildings.

The property must not include buildings principally used for income-producing purposes. Barns, silos, commercial greenhouses, or livestock facilities used primarily for the production of agricultural, farming or commercial enterprise are ineligible. However, barns, silos, livestock facilities or greenhouses no longer in use for a commercial operation, which will be used for storage do not render the property ineligible. Outbuildings such as storage sheds and non-commercial workshops are permitted if they are not used primarily for an income producing agricultural, farming or commercial enterprise. A minimal income-producing activity, such as HB-1-3555 12-4 maintaining a garden that generates a small amount of additional income, does not violate this requirement. Home-based operations such as childcare, product sales, or craft production that do not require specific commercial real estate features are not restricted.

Original question:
We are holding off on an appraisal, but we want to know: There is a pool barn on the property. Currently, the seller is allowing the neighbor to store farm equipment in here. Per my understanding, the borrower will not be allowing this to continue once he owns the home. Can we order the appraisal with the farm equipment in here and have the borrower provide an LOE on this, or do we need to have the farm equipment removed. In addition, there are two large diesel tanks in the barn as well. Please advise :)
