Spider,
Just a word of caution, in relation to georgisj reply.
If you are in sunny QLD it is now “inappropriate” to use a ‘Current Title Search’ ( from Dept of Natural Resources) or the commercial versions (ie RPData) for “marketing purposes”. In other words you cannot use this data to find out who owns a property and then approach the owner to see if he wants to sell. All to do with the Privacy laws. A lot of real estate agents are still coming to terms with this.
