The "F" that you see on some listing numbers simply refers to the local Association of Realtors where that listing broker is a member. In this case, the "F" correlates to the Southland Regional Association of Realtors which is in the San Fernando and Santa Clarita Valleys. A true foreclosure will be called an REO or bank-owned listing. A Short Sale will simply state that the property is in a pre-foreclosure state. I hope this helps.
I hope that clears this up for you!
