Seriously, is your first question about taking a loan here? Are you planning to take it to the UK and vanish? Now to answer your questions, loans to expats are capped to a maximum of 70k GBP. They are easy to get, but not necessarily the maximum amount as you have to have a fat salary to get it. You pay back your loan in 4 years maximum, and if you are fired you will have either to find a new job or sit in jail until your loan is paid back.
