Simple answer, no it's not worth it. Too much confusing information on the site for regular buyers. if there is a property you are interested in, you can email me and I can look up the information for you.

I personally have not had good experience with Realtytrac...
Are you an investor follow distressed properties to see which ones are going to be auctioned soon?
Although there is a lot of good information, many of the properties you see featured are there because they received Notices of Default or possibly Notices of Trustee Sale. Just know that not all of these properties will be sold or foreclosed especially if the owners found a way to resolve their delinquencies.
And those who are foreclosed by banks will eventually make their way to the MLS when foreclosing banks hire realtors to list the properties for sale. So if you're ready to buy, why not engage a realtor to help you find properties that are actively offered for sale. Your realtor can give you some insight or guidance based on the market condition,etc.
