Often the cheapest form of loan will be to ask your parents to re-mortgage their home. Assuming that there is sufficient equity. (Remember a secured loan will still have first call on the property should there be problems servicing the debt.)
A remortgage should facilitate the lowest rate of interest on the Capital advance.
Whirls is quite correct with her assertion that unsecured bank loans are not available at this time. Even HSBC have pulled the plug sadly.
You could always consider going to work thus earning the money to fund yourself perhaps? This would take a little longer though.
On a positive note jobs are starting to flow again.
