Cause:

This happens if the invoice associated to this property was unposted.

NOTE:  There are instances that a user will accidentally change a status from Pending to Closed or Processed without posting the property. Run the Posting Summary report to review the postings of invoices, payables, and deposits.

To fix:

1. Go to Sales
2. Go to Invoices
3. Click search
4. Choose the company from the dropdown list
5. Enter the property address as the customer (use the magnifying glass button to search)
6. Click search
7. Click post

Once invoice is posted, go back to the property and the close date will be showing in Properties > Basics screen.
