To my mind in following two cases it may not be regarded as IFHP
1. If the assessee is a CHS - The aim for forming a CHS is not to construct property and let it out. Hence the amount received by a CHS may not be regarded as IFHP
2. If the agreement between telco and the assessee is towards payment of rent for the space + providing other services like maintaining cleaniness of the spcace.. provision of security... installation of electric meter.. etc.(i am not sure as I have not studied such agreement) then a contrary view may be taken if it is benificial to the assessee..
