As a Realtor serving the Pittsburgh region, I am currently working with investors both local and remote.

Now with the internet and self serve website like zillow and etc, I'm trying to see how realtors will continue to survive in a world thats changing toward self serve to sell your house as well with so many entrepreneurial investors helping homeowners sell and buy.I'm not here to debate about realtors but, I think the realtors may soon become like the old CD getting replaced by ipods and itunes.
