Using the Google Street View image API you can submit either a set of coordinates or an address and have the latest street view image returned locally. See for example Phil Cohen’s Family Inequality post in which he shows examples of auctioned houses in Detroit over time. I think it is just a cool source of data though to be honest.

It has been used in criminal justice applications as a free source for second hand systematic social observation by having people code aspects of disorder from the imagery (instead of going in person) ( Quinn et al., 2014), as estimates of the ambient walking around population ( Yin et al., 2015), and examining criminogenic aspects of the built environment ( Vandeviver, 2014). For a few projects I was interested in downloading street view imagery data.
