Replying to Advice?

Hey guys, I'm having a little trouble that someone on here can hopefully help me with. Myself and 3 of my friends want to come out to co for the winter (January-April), but I'm having trouble finding a place to stay. It seems like no one wants to give us a 4 month lease, which I understand, but I don't exactley know what to do. If anyone has any suggestions or could even point me in the right direction, I would greatly appreciate it. Thanks NS
