In our city, alot of the houses and belongings we're saving aren't the ones that are on fire, but the ones that are exposures. It's very common for us to aggressively attack a known vacant/abandoned/decrepit structure because the occupied structure next to it is in immediate danger. (up to and including all ready being on fire on the exposed side)
I suppose though it's all in what you're used to. For alot of the posters on here 3 upstairs rooms and part of an attic would be called an "immediate defensive protection strategy."
We call that just another hour of our time.
