Mortgages - any alternative ways of buying a house?

i've just been having a quick look at how much i could borrow to buy a house. most mortgages work out that i'd be paying back 3 x what i borrowed!! that's such a rip off. are there other ways to fund a house purchase? i'd be a first time buyer so wouldn't have anything to secure a personal loan on to get a loan... show more i've just been having a quick look at how much i could borrow to buy a house. most mortgages work out that i'd be paying back 3 x what i borrowed!! that's such a rip off. are there other ways to fund a house purchase? i'd be a first time buyer so wouldn't have anything to secure a personal loan on to get a loan that big.

please don't suggest part-buy, part-rent schemes, i'm already looking at this but still need to fund the half i'm buying.
