Data sources and licences
Every finding in a report comes from the data below. For each one, this page says what we use it for, the licence we use it under, and how often it's updated. Where a licence doesn't allow reuse, or we can't find a licence, we don't show the data. We link to the official source so you can check it yourself.
NSW sales data is licensed under CC BY-NC-ND 4.0, which doesn't allow commercial use. HouseScan is currently a non-commercial preview and uses this data for estimates and nearby sales. Charging for it or any commercial use would need a separate licence from the NSW Valuer General first.
