Hi
1 seller have to apply to income tax Department u/s 197 for lower deduction of Tds
2 Tds applicable on total sale value
3 you have to pay Tds on payment basis
4 Property age not make any difference in TDS rate ( for getting lower deduction certificate it’s relevant)
5 sale deed value is relevant for this you have to produce same amount sale agreement ( generally two agreements made one for bank if loan apply and other for registration)
6 you have to apply for TAN NO
7 nri persons representative ie CA/ advocate can do all things on his/her behalf
8 yes Registered GPA case is considered
9 Yes you have to mention mode of amount paid to seller thus Tds amount reflects in sale deed
