Sorry to be stereotypical, but I would also be leery of any houses showing signs of "_____trash" (insert ethnic group of choice) as neighbors, such primer grey ricers with ground effects and coffee can mufflers, or stupidly lifted older pick-ups with rebel flags flapping in the breeze.
Hey if it walks like a duck and quacks like a duck...
