Brendan - Your proposal is not what I intended. I propose that only the rental income be given tax relief. This would make all the other arguments null and void and would make it clear and simple.
John rents out a house and gets 14k gross rent. If his mortgage repayment (capital + interest) is > 14k then he fills out a form 12 and pays no income tax. If he pays < 14k per for his mortgage then he is taxed in the same way as currently.
