Is Rental Income Halal?
I think It is this first phase of transaction which identifies whether resulting earning would be rent or riba, therefore it cannot be ignored. If it arises through a profit earned through loan transaction, it is riba (a well known definition), and if it arises through a profit earned through trading, then it is either rent income or normal trading profit. What distinguishes riba from rent is the presence/absence of a loan arrangement and loan is always in some form of consumable items.
