I missed this by email. But thank you for the follow up.
Basically, you want to removed property fields which are not custom currently.
Country and Listing ID are the items that appear always.
The rest don’t show if you don’t fill them in. They only show in compare page, which you can also edit.
The pages are listed here http://wpestate.org/forums/topic/edit-default-property-details/
If you want to delete the fields from the .php file and do these changes in the child theme, the process is a little more complex that style.css child theme.
You will need to de-register the php file you’re modifying and then register it again in child theme. This is the wordpress link for this http://codex.wordpress.org/Child_Themes
Hope it helps. And again, sorry for missing previous emails.
