A "pre foreclosure" just means that the ower missed a few payments (3). and the ad reads - "Notice of Default. This property has started the foreclosure process because a loan secured by the property is in default. The borrower/homeowner still has the opportunity to stop the foreclosure by catching up on defaulted payments or paying off the entire loan balance"
The house would probably not sell for the $259k outstanding mortgage or even reach the point.. the area is a 400k to 500k in pricing and it would probably sell as a short sale before even getting to the foreclosure point.
All that a "pre-foreclosure" on these sites is the bank selling the late payment information as a "lis Pendens" to "Realty Trac" or whatever inital company they used, so they can sell their service to you.. this may never come close to even being on the market.
You need to really read the post which also reads... "Please register for a free trial with RealtyTrac to access complete information for this property, including full address"
Usually after signing up and giving a credit card.. "there is no further information on this property"
Then people come to Trulia Q&A and try to get some information for free... crazy stuff, eh?
Best bet here is if you are really interested o the house, go knock on the door and get the answer from the homeowner.
If you are loking for foreclosures and short sles, give a call and I can see what is available in the area that you are lookijg and see if there are any buys going on...
