I don’t have any subscriptions but what I’ve had luck with at least in my area is going to Yahoo Real Esate and finding the foreclosures by street. They used to give the address, but I don’t think you’ll find it anymore, just a description. Take the info (sqaure feet, # of Br, Ba) to Zillow and find the same street and you may find it.
In a tract it may be more difficult because more homes will be the same size. It may also be hard if there are several hundred homes on one street, but I’ve been able to find some doing this.
