The address is hidden as the best way to commit fraud is to use bait and switch. That is what is happening here on the realtytrack foreclosures.
If you are looking for foreclosures or bank owned homes advertised by RealtyTrac, you will not receive a complete address until you pay for a membership. Save your money and contact a Realtor in your area, who can help you find properties as a Buyer's Agent (who work for you, but the Seller pays the comission).
Good luck on your search,
Unwavering Commitment to Service
I am not sure which property you are referring to but some agents do not list the address because you need to contact them directly to find out any additional information. I would be glad to provide you with the information for any specific properties you are interested in.
