Realty Trac is it's own entity and you must deal with their service reps to answer your question. You ARE welcome at any time to search the full MLS database and all the foreclosures too at my website http://www.infoarizona.com.
I use RealtyTrac to advertise. I would love to assist you with using that system. Let me know exactly what information you are looking for that you are not finding. You also might want to check out my website at http://www.RanchoElDoradoRealEstate.com where you can find a property search feature for properties listed on the MLS.
I can set you up with auto-emails in the areas that you're interested in. It will give you all of the details that you will need. I can also provide you with a market analysis on any given property as well as tax records if need be.
I can set you up with a personal portal through the mls and you could search there without any 'trial' membership :) ......the question is one for realty trac themselves do they have a contact us area?
Again , most happy to assist as a buyers agent should that help in your search. Warm regards, Cristine
