I agree with Re-Heat. If your folks are risking losing their home over your training you're putting yourself under a hell of a lot of pressure. There is enough pressure involved in getting your fATPL as it is without that sort of worry.
Work full time and save like mad, borrow from a bank what you can, apply to the likes of CTC who will help you arrange a loan, anything but what your parents are suggesting in my opinion. A flying job ain't worth seeing your family put out on the street mate.
Good Luck
