Do you really want to bet your parent's home against your getting an airline job in the current market?
You can't "bet your parents home" only they can. Most parents are fairly shrewd when it comes to lending to their offspring. The route the poster has been selected for, has been placing almost all of its "wings cadet" graduates with airlines straight after their 16 month courses recently. That is no guarantee of anything in the future of course, but given the "current market" you can perhaps understand the posters question.
