Hotpads.com presents various types of housing maps, including those that cost out buying vs. renting over time in certain areas. One new feature of the site is a heatmap showing foreclosures, with most large cities nationwide represented. I didn't find any on my street, but there's a whole cluster - four at the same corner - just a block away, which leads me to be rather suspicious of the map - being that all four listings are for the same house. It's a neat tool, but take the data with a very large grain of salt.
Additionally, to get more detailed info, you need a free trial or paid subscription to RealtyTrac - at least you did for every property I looked at. Not sure if this is just a come-on for RealtyTrac or that was just a coincidence. Still, it's an interesting way to look at how some folks (and by folks I mean both brokers and buyers) greed and bad judgment is costing us all a hell of a lot of the equity we've built up over the last decade.
