propertyadguru.com welcomes a guest post from Ryan Hinricher:

Establishing yourself as a successful real estate professional in 2010 can easily be a daunting task. The real estate market is unrecognizable when compared to just a few short years ago. In 1994 the first online real estate listing was published in an email by Eric Hilding of Coldwell Banker in Morgan Hill, CA which changed real estate forever. Within 1 year ERA launched the first listing portal with over 50,000 listings. Today we have Zillow, Trulia, Twitter, Facebook, iPhones, and thousands of other tools and technologies which power the new real estate economy.

Because of this, it’s easy to become overwhelmed and impossible to stay ahead of the technology curve. I thought I’d put together a shortlist of critical components to your online real estate foundation. These are the building-blocks of any real estate business and most aren’t sustainable without them.
