Sec.195 tds - payment to nri

Sir,

A Property is about to be purchased from a relative of NRI, the NRI has given a general power to his relative, to act on behalf of him and make the transaction. The Buyer is a individual, not subject to Tax Audit in the previous year.

I have a doubt whether TDS u/s 195 @ 20.6% is to be deducted on payment made to the relative of NRI ? 

(Note: Buyer does not have any TAN Number, the transaction is about to be entered) 

Thanks for any replies.
