One of the largest, if not the largest growth areas on-line is the use of web sites for real estate searches for listings , local market statistics and demographic data, and home value estimates.
There are a multitude of sites offering listings and real estate information for Phoenix , Scottsdale and the many towns in the Arizona Valley.
More than ever, consumers start their home buying (or selling) process on-line. A great idea, and something I recommend. However, I also suggest that you enlist the tools of more specialized and localized professionals, Realtors, neighbors, news outlets, etc... to either confirm or help assimilate all the information on hand.
Real Estate is not (yet) like stocks and bonds. Real Estate is not a commodity. It is a tangible asset. An emotional bond. Decisions are made with the heart as well as the mind. Numbers are critical. However , for the most part, numbers, charts, graphs alone cannot completely replace the emotional and human aspect to real estate.
I encourage you to use the information on-line, in conjunction with localized experts and make sure you touch, look and feel the areas, neighborhoods, and home.
Only with all of these tools can you make the most informed decision.
This is in fact one of the resons I got into the business. I see a lack of the tools being used by the local agents in my market. There is of course Zillow and Trulia but even they have low participation by local agents. I think that this is leaving a large segments of the market(Gen X and Gen Y) unserved.
