If you respond to the ad and they send you an email back saying they are out of the country and want you to have the house you will know there is something fishy about the ad
It is hard to say whether this is fraud. The reality is this...$900 is not the market rate for such a home. I do not know whether they are talking about a studio, a shared room or the entire home. But most homes in the Santa Barbara area with that view will rent for $3000 and above.
Hope this helps.
