expect to pay about ~$500 for a room (which isn't bad if you ask me). I've lived in squaw for the past year and a half and my rent has been in the $450-585 range, not including utilities. i know a lot of people who have cheaper rent, while some have higher...just depends on the house and location and how many roommates you wanna have.
but can't complain...deciding to move to tahoe, specifically squaw valley, has been one of the greatest decisions I've ever made.
