The house which I live in now is part of my job, it has an ag tie to it so the rent is very reasonable, the thinking behind buying my own is security if ever I find myself looking for accommodation.As you don't already own a house, you would be better buying your own to live in.
You will get a good deal on a mortgage and no stamp duty to pay on your main home.
Save hard and look at a buy to let once you've got yourself on your feet.
If I can pay a deposit and the rental income pays mortgage plus surplus then that would be very attractive
