Nope it was a scam and has been removed from Postlets. Anytime it seems too good to be true, it usually is.
By the way, if the listing is missing:
1. The name of a recognized LOCAL real estate firm
2. The contact information for a LOCAL Realtor
3. An exact address of the home
Then run, do not walk, to report the listing to Trulia or the website where you find the posting. 99 percent of the time, the information is false and intended to part a consumer with his/her money.
Thanks for pointing this one out to me. I've already flagged it for Trulia.
