In a survey done in 2004, it was discovered that they live until an average age of 11. I think that statistic would be slightly different now and they would live till a little older. Even at 11, it is quite a decent age for a dog to live till.
As you can see from the video they are also quite large so a large area would be needed to give them proper care. They would need to be walked lots and given lots of attention
Malamutes are quite known to howl a lot too and that could cause some noise problems if living in a built up area especially at night time. It could lead to noise complaints from neighbours.
