20. Brownsville, Texas

A border town, Brownsville is one of the most patrolled cities in the country for illegal immigrant crossings. With a handful of arrests happening each day, constant authoritative presence makes it a tense place to live.

Naturally, this makes it hard to sell property in the area, as most people would prefer a more relaxed environment. Of the people that do reside in Brownsville despite the drawbacks, about 31% live in poverty.
