I agree that putting the building on the map should rank higher than giving it a lifecycle or damaged attribute that hard to assess from the image quality. 

This is also the approach I recall from HOT disaster mapping. Roads and building from satellite, destruction details from ground crew. (Admittedly I might be wrong here).
