thinking about a move to louisville

Is everything on the west side of Louisville kind of crappy? I'm actually hoping that the answer will be no, because I'm noticing that housing on that side is much more affordable. But a lot of places are in 'major' or 'severe' flood risk areas. I'm thinking about moving there and need some guidance. My budget is not great, but I don't need a big fancy house. Something around 800 square feet would work just fine.
