We own 2 flats in the same house. We live in the upper flat and rent the lower flat to our grandson. We are both pensioners and not in good health. He is young and although working he doesn't earn much but it is reassuring to us that he is on hand to help us . Some months we let him off the rent and also we bought a new kitchen for his flat and let him off paying rent for 2 months as he installed it himself.
Just out of interest, are we obliged to charge him rent. We only charge £250 a month. Are we allowed to let him off paying some months? We do self assessment online. Do I just divide what we have received by 12 months and put a note in the self assessment form as to why it's so low. He pays his own Council Tax etc.
Any information on anything we should know about this arrangment would be gratefully received.
