I think 10 is pretty much non existent but you'll be offered new fix term deals at the end of your schedule but if right wing idiot crashes your economy (looking at you Liz Truss) just before your rates are due to move to tracking you'll get shitty rates. Moving to tracking at the time was scary as hell....2, 3 and 5yr fixes are the norm - think you can get 10 as well, though not sure how common they are
I think in general UK folks are more likely to move at the end of their fix terms but moving up the ladder is usually what happens as you build equity. Housing being way more unaffordable and most people start in property with nowhere near enough space.
Yeah because you guys gave them to people who couldn't afford them and crashed the world markets when the bubble burst! Does no one actually know what happened? The US subprime mortgage system collapsed.Adjustable rate mortgages were very popular until the 2008/2009 downturn.
