Sure, for some things.
HomePrezzo uses property and suburb data from CoreLogic or Pricefinder in Australia, or REINZ in New Zealand to produce market stats and recent sales reports.
But if you don't have an account with either of these providers, you can still use Homeprezzo.
Listing Videos are powered by your CRM provider so no external data provider is required.
