Featured Image – Category or Status Text Overlay

On the paid WP-Property themes there are category or status overlays on the feed’s featured images. For example, on the Avalon demo (https://demo.usabilitydynamics.com/avalon/) there is a section called “Pur Latest Properties” where the featured photo has an overlay with the category listed such as “Single Family Home” or “Apartment”.

Is this possible to achieve without using their theme? We would ideally like to add status categories such as “Sale Pending” or “Sold” so that these would be displayed over the featured image. Any help would be much appreciated even if it is just to point us in the direction of how to edit the php/code and accomplish this ourselves within a child theme.
