Alleys in Dallas TX are a great tool to predict future community appreciation.
Drive down Dallas alleys to view backyards. How trash and other undesirables are disposed.

The alley also tells the upkeep of the community. Whether back porches and patios are maintained is a good indicator of how other aspects of the property are maintained as well.
How are the fence and property seperators being maintained in the rear and rarely seen areas. This is a sign of how well the community is maintained also.
If the alleys are not well maintained, other areas of the neighborhood will become unmaintained as well.
Alleys also reveal how much neighbors are willing to go out of there way to hide things they should. For example campers, children toys, basketball goals, trampolines etc...
