I can't speak for the USA, but incase you get sent to Granada. Our class rent averages at around 1000EUR per month. You can find better deals, but accomodation can be a bit complicated if you're on a visa, and as with any location - pricing is all dependant on what time of year you're going.
For PHX, the winter is actually peak pricing as I understand it. And in Granada, if you're near the east of town then it's peak at winter because of the ski resort. But otherwise, it's usual summer peak pricing.
