Grab all identification you can muster, and I'd say laptop, photos, etc. that has sentimental value - but don't overdo it. I suggest also calling your insurance

Grab all identification you can muster, and I'd say laptop, photos, etc. that has sentimental value - but don't overdo it. I suggest also calling your insurance company now, let them know what's likely to happen, get a case opened, that way when the house is toast, things will already be moving for you.
