Everyone has to make sacrifices, and many perhaps your and my age (23) are mortgaged up to the eyeballs - its the only way we can manage to get on the property ladder. My husband and I bought our first house 3 1/2 years ago, and we were very lucky to be given a deposit as a wedding present by his parents. We were on an interest only tracker mortgage, and it cost us nearly �700 pcm (regularly varying from �620-�720 being a tracker!). I could never in a million years have got a mortgage on my own, so don't panic, you're still young! We were advised that if we weren't planning on staying in the property for longer than say 5 years, to get interest only, as that would be all we'd pay off anyway on a repayment mortgage. Also, if we had less than 10% deposit, to just put down 3%, as the difference was minimal month on month, but left us the cash for stamp duty and fees etc.
All of this was advised to us by a mortgage adviser - you have to speak to one, as everyone's situation is different, and an adviser will know the perfect product and the best deal for you. Perhaps you and a friend could go in on a mortgage together? Maybe move back to your parents and save up for a deposit? and ask for 'bottom drawer' items for birthdays / christmas?
I know how you must feel, I felt the same way and i know its frustrating, but don't rush into it (especially at the moment), a mortgage isn't something to take lightly, its a huge commitment!
You've got the perfect opportunity to get free advice from your employer, who'll only be happy to help you out so don't be scared or embarassed to ask
good luck x
