FlyerGuy,
Options: Well may be
1. Buy a house and borrow a shed load more and use that to pay for your course. And at the same time get your spare room / rooms rented out. Thus paying a pecentage of the morgage.
2. Ask your old man nicely if he wouldn't mind re-morgaging for you (I am assuming he has one.)
(Your Dad could say he wanted to do some home improvements. Extension etc.) You can, in turn pay your Dad back. And the rates will be lower.
3. Go back to the back and explain in more detail that you need their help not there crazy 8.7% rates. Funny how banks are so helpful when you have a good paid job. Then you tell them what you want to do and they become unhelpful.
I am sure others will have better ideas. Just some options from me.
Happy days
