Good on you for saving to do it. Very wise. You will not be risking your future by having mega loans etc.
Don't discount a second job also, I have work 7 days a week for 3 years, and during that time I have completed my atpls, passing them all first time.
But bewarned, it is hard. You will have no social life! Look at every way you can to make money, I saw a bargain car and turned. Grand profit on that, made some on shares, sold gear on eBay, even cycled to work to save on fuel. It is possible, but you won't have much of a life while you do it. But in my mind a better life after training than some muppet with a 100k debt paying 1000 a month+rent after going to Oxford and a low paid first officer job, or worse still no flying job.
