a proper introduction.
We verify the agency and your authority before publishing. Supply listings you represent and images you have permission to share. The current launch collection starts with KnokKnok.
Approved agents can import up to 25 listings at a time using our JSON template. Update availability promptly; partner listings pause after 30 days without a refresh.
Who’s There? is operated by KnokKnok Real Estate. Your private enquiries and listing insights stay with your agency. Any separate KnokKnok buying service is a buyer’s explicit choice.
