There's lots of cool options:
I've got a 3 month rental on the NH seacoast starting Oct. 1. During the peak season, these places rent to tourists for a few grand a week, but off season, you can get an amazing deal and still enjoy the beach and the stunning fall foliage.
If it's "off season" where you're heading, look for any hot tourist spots and see if you can strike a deal over a room. Most of these places advertise online.
