If you are seeing the wrong address in Tenant Turner, or the addition of a unit number that should not be there, it is likely due to the address field you are using in Buildium. This article will guide you on how to adjust that.
To update the rental address, first find it under the Rentals > Properties list in Buildium.
Open the address in question and then navigate to the Units tab. Click 'edit' by the resulting address.
Update the Street Address BELOW the initial Unit field.
Be sure to save your updates so the change appear in Tenant Turner as well.
