That dwelling in the photo was absolutely 100% certainly NOT a total loss and I would be stunned if it were torn down. This fire was not in the home, it was in a porch to the rear and extended in.
Can't tell exactly how far it exrtended in but looks like our situation. Fire went in about 10-15' and into the attic. they wrote it off.
I would be stunned if your FD actually confined a fire to one room and the attic using the tactics you spout off here.
And what tactics are they for an occupied residential with minimum fire showing? make entry and operate to extinguish. I don't think I have ever talked about anything but that for that situation.
If it was a vacant residential or abandoned, it would be a much different situation.
