But you'd be using savings to pay it off, ergo if you didn't pay it off you'd have more savings, and be able to invest it/grow it.For me personally, it's peace of mind should I lose my job that I'll aways have a roof over my head that I no longer am indebted to anyone for. And also, that any savings I have will also last longer should I be out of work for any extended period of time as it wont have to cover a mortgage payment, just the essential bills.
