Are you integrated or modular. If the latter, it should not cost that much.
You could try and get a couple of loans. To clarify, if the max payment terms are 6 years with hsbc then look at other banks who may do 10-12 years. A longer debt period but more managable payments.
e.g £20,000 fro HSBC over 6 years £30,000 from other bank for 10 years.
This could run beside a lower loan amount from hsbc.
Also, if you take a loan and can't pay it back due to no job etc. A bank will not immediately send the thugs round to collect. Generally, they will look for interest on the loan payments.
This can ease the pain until a well paid job comes up.
Thats if banks want to give you the money of course. And remeber that banks that do not do the HSBC study loan thing, do not really cater for that, no matter how much you explain it to them. So think of another reason.
Good luck, and hopefullly you'll find a cheaper way. I had to sell my house to fund it. Some people call that brave.......I know what I call it!
