One option which seems to be missed out on a regular basis, is re-mortgaging a property (either your own, or a kindly and gullible relative - I chose the latter).
Not only do you benefit from interest rates you will be unlikely to get for other types of loan, you also get longer to pay it off meaning lower repayments (handy in the curent job market), and you may be able to borrow significantly more than any bank will be prepared to loan you (handy for all those extra costs nobody told you about!).
I appreciate not everybody is fortunate enough to have relatives with a mortgage-free property against which to borrow, but in a (presently) rising property market and with course prices rising just as fast, it is a worthy option to those able to take it.
