Using these resources is an important part of today's buying process. They help people to become informed about the local market, identify neighborhoods, get a feel for price points etc. etc. But make no mistake, these resources will not replace the real estate professional because there is so much more to the buying process than identifying home possibilities.
I would only assume that as a future Florida buyer that you would want to know about the Chinese drywall, community development districts, details of the local HOA, price comparison information, etc. etc. There is much more to finding and buying a house that looking at pictures on the computer.
Ask yourself, why so many attorneys use the services of a professional reator?
