I don't wish to come across as cynical, but if you find a bank willing to pay for that , at this moment, please let us all know.
The problem is , 500hr = exactly that, 500hr. . . then you will be out of the door & they will take someone else's money for the next 500hr.
Would you like to hazard a guess how many A320 rated F/O's with MORE than 500hr on type are unemployed at the moment?
Maybe worth asking yourself the question guy ?
For my money you would be better concentrating ( if you must pay. . . which I accept in the current market you may have to do ) on the Ryanair's of this world, who at least give an open ended contract at the end, rather than Easy Jet , who
AFAIK are only offering 6mths. Next Winter will come along quick enough and your 500hrs won't help one little bit. In Ryanair you may have a very slack winter, but you will still be ( in a manner of speaking) in a job.
Just a thought before you land yourself in debt that you may not be able to service 500hr later.
