During peacetime, hospitals can be indicated by a variety of symbols. For example, a white 'H' on a blue background is often used in the United States. During times of armed conflict, a hospital may be marked with the emblem of the red cross, red crescent or red crystal in accordance with the Geneva Conventions.
You can typically stop paying for mortgage insurance once your loan is paid down to 78 percent of the original value. In theory it should automatically cancel, but there are situations where it could take somewhat longer or even considerably shorter than that.
The premiums for the policy are included in your monthly mortgage payment. Once you have paid down the mortgage enough that it is less than 80 percent of the value of the home--78 percent in the case of government-backed loans--you no longer need insurance, and the premiums stop.
