Well, as a real estate professional that uses this website it is up to the agent that lists the home to allow you to view the exact address of the property you're looking at in hopes that you'll contact them directly to get more information about it.
If you want a website that will give you all of the information that you need you can use my website if you would like. It requires you to register an account but even if you're working with another realtor I welcome you to use my resources to help.
I do not specialize in foreclosures but I do work hard to get the lowest price and best terms for you as a buyer's agent.
Let me know if I can help in any other ways.
