You have a solid degree, experience in the field, experience in the air and your contingency plan seems sound, as long as your parents can be guarantors you should have no problem in getting the loan.
I personally believe if you perform well in flight school and posses some fairly competent social skills, you shouldn't have too much of a problem when it comes to finding a job, given your experience and maturity.
Furthermore if you cannot find employment post training, you always have a decent fall back into a well paid job until the industry picks itself up again.
You have covered your back and have gone about training in the best possible way, well done and all the best to you matey!
