8 years is a 5 year fix had they already bought and some over payments on top
so not an issue for most sensible people.
Its nothing to do with sensible, your defining sensible, and against what most of the population seem to believe.
Most people do not overpay. Many people take out a mortgage and just let it run, they don't see a need to get a high equity percentage and value other things higher than clearing the mortgage.
Plenty of people also don't have the ability to pay a significant extra payment, and as I already pointed out to you buying is actually usually cheaper than renting.
Just because people choose a different balance in life doesn't make them wrong or you wrong, everyone is different.
I dont see the point in 4k TVs as an example, sure they look a bit better, but to me they offer no increased value over a normal high def, if I am watching something worth watching i become engrossed in the thing I am watching and then start paying pretty much zero attention the blades of grass blowing in the wind. BUT i understand why some people may think its worth it, they value that and consider it worth paying extra for.
Me I would say anyone who has a mortgage and is wasting money on super high def TVs and stuff like that should pay the money off the mortgage, but thats just me.
