During the application of our l-129F last Dec.'12, i wrote my Abu Dhabi address as my present address on all my application forms and Philippines as my home address.. I came home to the Philippines end of Feb.'13 for good and from thereon, everything i fill-in is my Philippines' home address.. So far, there was no issue about it..
Just dont forget to obtain a police clearance from Dubai at least before your UAE Residence visa will be cancelled.. It would be of your advantage to have it on hand, just like what i did..
Good luck!
