I noticed you've asked the same question about a couple of properties that appear to have very low prices. You probably found those properties by clicking on the "foreclosure center" button on Trulia. Well Trulia has a partnership with RealtyTrac, in which RealtyTrac displays homes that are in some stage of foreclosure, and shows the amount due on some loan, making it look like a purchase price. This is misleading and trips a lot of people up. It's unfortunate that Trulia continues to allow this.
If you want to get accurate information on foreclosure properties, you can just ask a realtor. We can do searches for you based on the area and price range you need. We can even set you up with automatic emails, so the moment a new foreclosure hits the market, you'll be notified. This is actually the best way to get a good deal, since hot properties don't sit on the market for more than a few days. Many times they also get multiple offers. Again, a good realtor can help you determine what makes sense in terms of an offer that stands a chance of winning.
If you'd like me to do a search for legitimate foreclosures for sale, or set you up with automatic notifications, please let me know. Good luck!
