HSBC will only lend upto £25K unsecured and upto £50K secured. If you take out a career development loan, they will take that into consideration and minus it against the £25K unsecured you have taken or £50K secured. The loan is only available if you are a potential student with either cabair or Oxford. The loan is not available to modular students.
In a nutshell you cannot take out more than £25k unsecured and anything over £25k must be secured on a property, land, market shares etc.... borrowing more than £25k unsecured or £50k secured will not happen and HSBC will review how much debt your in so graduate students are most likely to feel like
when their application fails due to student loans taken out.
I hope that helps and remember, dont bother applying for the HSBC Professional studies loan if your not going to train through Cabair or Oxford. Modular students have always been declined since it was stopped a few yrs ago. If your not gonna train through an intergrated school then speak to your local bank and see what they can offer.
Kind regards.
