Thanks for your question and regret to learn of your friend's urgency in India.
Prior, to leaving your friend could have given you a Power of Attorney, or if he has done this before
then he is quite aware that the Documents can be signed at a US Consulate in India.
Please note this "specific power of attorney" is only good for property address that was created for only & not the same as general power of attorney - Hope this help.

Talk to your Title Company; they can probably e-mail, or Overnight the Documents and arrange for the Notary. They will help you arrance for Money Transfers, etc.
You probably can arrange for a Power-of-Attorney for your friend; but you probably do not have to.
