Residenial mortgage - both primary resident and his parents live in the property

Would become grey if for any reason your parents claimed a financial interest in the property in the future , having given you money. Without a formal written agreement. The matter becomes open to interpretation.

Understood and thank you Deleted_User.
My apologies for asking so many questions but I have one final one - how can anybody prove that i'm 'taking money in exchange for providing a home'? Can't I simply claim that these payments are unrelated to the mortage? There's no contract or tenancy agreement in place, I'm simply getting some extra cash from mum and dad...i know it sounds a bit far-fetched, but how would one prove intent here?

Depends on the value of X but my thoguh would be they are a lodger and therefore the second applies. There is an annual allowance for a lodger before tax is due. 

They could be the brother's lodgers because he lives there but not the OP's.
