POA can be made anywhere you live. the purpose of POA is to give authority to someone as you cannot go or do the work on the required place. 

You can prepare POA anywhere on Rs 50 stamp paper and get it registered. do not forget to get it prepared cautiously by a lawyer only as mistakes can cost you heavily.

the attorney holder then can use it to transfer your property on your behalf.

if any official denies it then file a RTI application that why the attorney transfer is not being done and under which rule or law. you will get his objection in writing then you can move to court if you have adequate grounds and get directions from there.

good luck

POA is a public document once it is executed. You can execute a POA in favor of any person at any place at anytime to act on your behalf in your absence. Your right in personam gets transformed to right in rem once POA is executed. It doesn't require any stamp duty in proportion to sale consideration of the property. It has stipulated franking or stamp of RS. 300/- getting which POA can be executed. 

Its advisable to stay in loop and accept sale consideration into your bank account vis-a-vis POA so that there are least chance of it being misused.
