FICO hit after the foreclose

[Miknan]

My Ch 7 has been discharged and closed. The house was included in the bankruptcy but has yet to foreclose. I checked my FICO and it's about 660. After the foreclose actually happens how much more of a hit will it take? I was under the impression that all the damage was already done since the house was surrendered in BK but I found out today that isn't the case. Pretty disappointing.
