Over at
HarrisonburgForeclosures.com, I post notices of upcoming Trustee Sales (foreclosure auctions). The graph below shows how many trustee sale notices we've seen over the past 7 months.

As you can see, there has been a general increase over the past seven months, though it certainly could be a seasonal cycle since I don't have 12 months of data yet.
Do remember that these numbers do not indicate how many properties are actually foreclosed on, but rather the number of properties for which a trustee sale is scheduled --- regardless of whether it ends up taking place.
I'm working to get my hands on data about how many sales actually go through. Stay tuned!
