Your question has been asked many times on postings from Realtytrac. (you may want to search on that to see what I mean). I would suggest a different approach to get the results that you are, no doubt, searching for- specifically to find a home, at a good price, that meets your family's needs.
1. work with a buyer's agent- you can review respondents on this site to determine someone who seems to meet your 'personality', seems qualified and knowledable and can negotiate on your behalf.
2. Get set up on a client portal, hopefully using MLS or one that feeds directly and automatically from MLS, to review REAL listings that you could consider.You can be as specific as you want a certain type of roof, or RV access...in more detail than you can driving by homes. You can easily specify that you want a certain elementary school area...any desire you want can most likely be described in your search.
3. Have your buyer's agent work with you to obtain preapproval from a lender, coordinate showings on houses, and help you understand the difference between short sales and bank owned homes, and the strategy you might employ.
Finding a listing on Trulia, especially if it's listed by realtytrac, is going to just end in confusion for you. Good luck!
