I am aware that the rules state that you cannot claim Property Allowance and Finance Charges, however I don't know if having a mortgage means that the client cannot claim Property Allowance. I.e. do I have to claim the mortgage interest relief?
In my client's case, claiming £1000 is more beneficial than actual expenses plus mortgage (it's a jointly owned property, so the total 'expenses' are £1500 including mortgage interest).
This might be a useful tool going forward if we can, especially as no Higher Rate relief is given anymore.
