Urgent -Pls help with query on Section 195 IT act

Section 195 of Income Tax act states as follows;

Subject to rules¹³ made under sub-section (5), any person entitled to receive any interest or other sum on which income-tax has to be deducted under sub-section (1) may make an application in the prescribed form to the ¹⁴[Assessing] Officer for the grant of a certificate authorising him to receive such interest or other sum without deduction of tax under that sub-section, and where any such certificate is granted,

The rules mentioned above are as follows:

13.  See rule 29B and Form Nos. 15C and 15

rule 29B subrule 2 states

Any person entitled to receive any interest, or other sum, on which income-tax has to be deducted under sub-section (1) of section 195 may, if he fulfils the conditions specified in sub-rule (2), make an application for the grant of a certificate under sub-section (3) of section 195 authorising him to receive without deduction of tax under sub-section (1)

Sub-rule 2:

The conditions referred to in sub-rule (1) are the following, namely :—

           (i)  the person concerned has been regularly assessed to income-tax in India and has furnished the returns of income for all assessment years for which such returns became due on or before the date on which the application under sub-rule (1) is made;

(3) The application under sub-rule (1) by a banking company shall be in Form No. 15C and by any other person [referred to in clause (ii) of sub-rule (1)] shall be in Form No. 15D.

As a Non-resident I have not been assessed to income-tax in India for the last 7 years. Does this mean that I cannot apply for the certificate for non-deduction of tax at source? I am selling a property in Noida. Will the buyers have to apply for this certificate?

Thank you very much in advance for any help and advice you can provide.
