I'm looking for a good place to rent in Las Vegas for a family.?

I'm planning on going to school at UNLV to finish a grad degree and need to find a place where I can live with my wife and three kids while on an extremely limited budget. I want a place that feels safe enough that we won't be constantly worried about our kids safety, but we are going to be living on a very small income. Does anyone have any suggestions on places that will work for me?
