One of my friend was in the same situation or even worse as he had an outstanding of almost 350,000aed. He negotiated with the bank and was able to convince them as he has an offer, will be able to pay back in some equal installments. So its better talk to them , show your offer letter and tell them will pay off in some equal installments. Bank will not get the money back once you are jailed off and also you can run for a while, but if you are positive enough you can always talk to them and finish it off. All the best.
