Why did I post that? Because more than a few people on here don't seem to know what they are talking about.
Go on, take out your 100K loan and put a second mortgage on your parents house. When Qatar decide at the end of course that they have changed their minds you will be in a pickle. Qatar is notorious for treating its pilots poorly so don't be surprised if the contract "changes" a few times. You may even end up in a desk job like the Wings guys.
