It's good that you asked, because this is a scam to steal your money. Never, I mean NEVER, send any money to someone you do not know. These scams are rampant and the way to avoid them is to always meet the owner or the property manager in person and verify who they are and if they can legally rent you the property. Property owners names are public records that you can find out at the County Recorder's Office. Property managers must have a valid license from the BRE (California Bureau of Real Estate).
