You can contact the listing agent who will be able to help you learn more about that specific property (and probably will know a lot about similar properties in the area). To find an agent, just click on the yellow button on the property's Trulia listing and you will be able to start a dialogue.
Please let me know if you have any questions or if I can help with anything else. I am happy to be a resource for you. Good luck with the search!
Not all preforeclosures are sheriff sales, so this may never go to auction. If it is a bank preforeclosure, it could take two years to come to market. I would keep an eye on it or have a realtor send you other foreclosures that are ready for sale now.
