Credit file check may be worth a shot bud
To find out whats going on.
Where did you try ?
As some places are stricter than others i've heard.
Either that or you have a low credit rating
Have you ever had things you couldn't pay off ?
Or paid a few things late that may be whats holding you back (it may have been marked on your file).
Or if you have credit already such as a
Mortgage
Contract Phone
Loans/Finance
or
Credit Card
The balances on them may affect what you can borrow and the decison or its the credit crisis affecting you and the are banks tightening up on who they lend to unlike before.
But i'm sure the credit file check will clear everything up and show you why your having problems..
Good luck
