I'm assuming that you recorded the lease payments as rent payments. In doing so the asset would not be listed on your general ledger. If you just need to have it listed as a structure you can simply go to the Barn Tab, right click on the farm and add a structure. If this structure needs to be on your general ledger with a cost then you would do the following:
1. Go to Payments/Purchases 2. Select the Structure icon. If you already have created an icon, the building will be in the list. Otherwise go ahead and add the name. 3. Enter the value that you are wanting to show on your books. 4. Click OK. 5. Go to Other Expenses and Payments. 6. Select Other Accounts. 7. Highlight your Equity Account. 8. Enter the same dollar amount as a negative value. 9. Click OK. 10 The difference will show Zero. 11. RECORD.
This will add the structure to your books and be offset by your equity account.
