No catch. I'm a pretty decent guy to live with. My room smells like shit, but I keep the common areas pretty clean. Plus HD Cable with all the bells and whistles. It's also a good area, compared to the surrounding neighborhoods.
Also, I'm not sure where you live, but 325 in Buffalo is not like amazingly cheap. I know compared to rents in big cities like New York it's beautiful, but when the average person makes 25k a year instead of 50, rent is low.
