A certified listing is only done once with one of our photographers (available in most larger cities). It is a free service, and will automatically increase your ranking on the site.
If you are interested in this service, and if we have a photographer available in your area, send an email to firstname.lastname@example.org indicating your city, as well as the link to your listing.
If we don't have a photographer yet in your city, know that we can also certify your property through a video call on Skype. We would then verify your property through webcam.
