Are they all the same variety? Is there any suckering or growth near the base of the plant? Maybe your plants are supposed to grow straight up, looking like trees...and maybe you won't want to prune them after all because they're growing just right for the location...or maybe a light shaping will be enough, and you can enjoy those plants as they are. See, crape myrtles can grow into different shapes. Some resemble tall and straight trees; others are short and rounded, looking more like shrubs. The planting scheme along the sides of your lot sounds as if that batch might have been intended as a hedge or windbreak. Those previous owners may have selected for plants that naturally have a tall, tree-like shape...because that shape best fitted windbreak purposes.
