This question posted by "HubWiseRealty' suggests an alternative objective....right?
Where one obtains data is directly related to the purpose for that data. For personal amusement and entertainment, Zillow and Trulia are amusing places to gather data. Also great places to direct others to spend THEIR money. However, if you are intending to commit YOUR money based on that data you really need to consider 'serious' resources. As HubWiseRealty, you know what those 'serious' resources are.
Best of success to you.
