Thanks for the feedback
WWW. I value your comments as you've actually been down that path yourself.
What I need to consider very carefully is what my backup is when the repayments start. What (or who) do I have to fall back on?
I think I'm obliged to borrow a good chunk but your comments convince me that it would be more than just worthwhile to offset what I need to borrow with some sort of job.
