I assume you want to prove your residence address to the leasing company is it?
if thats so... theres a work around for that problem.
Just goto any bank that you have your account and tell them that you have changed your residence and need to change the bank passbook accordingly. They will ask you to write a letter and change it immediately and issue you a new passbook with the address.
Take a photocopy of that book first page and submit it to the leasing required documentations
Hope that was what you were asking???.
