Thanks for reaching out.
You would have to do your own customization's to achieve this goal. Theoretically, the owner of the listing is available in the variable that build's the listings. However, the method of using the get_userdata(user_id) wordpress function and displaying their information is something you would have to do.
You should be looking for the function basic_listing_layout() and the $result variable should have the "user_id" in it.
You can suggest this as a feature on our bepro listings forum. Or you can request that we build a custom setup for you which does this via our contact us form
Hope this helps
