This is most definitely a scam. For a property like that in that location the rent should be closer at least $2000 a month. Be careful and remember if it is to good to be true it most likely is. Also, Craigslist is probably the best site to go to for rentals but there are many scams there as well.
I'm pretty sure that rental listing is a scam, so please be careful responding. $600 a month is much too low for a 1700sf, 2 bedroom, 2 bath condo/home/whatever in the Santa Barbara area.
