We are moving out due to the LL selling our house.
For context, we had been complaining of damp issues from a multitude of structural problems with the house, for over a year the LL was doing everything without actually doing anything to fix the problems, and when it finally came to starting the damp proofing and building work, she said she couldn't afford it and would sell the house.
There is deterioration from the effects of damp, on the walls and skirting boards. We have a toddler so any marks on the walls will be repainted and we will leave it as best we can - it was NOT clean when we moved in, I remember cleaning the toilet with a brush and huge chunks of limescale build up fell out from inside the ring of the toilet bowl!
The problem is my mum thinks we should pay to have professional cleaners do an end of tenancy clean. I personally don't think we owe the LL that much, and don't intend to leave it "dirty" either. She thinks we risk losing our deposit, but anything actually wrong with the house when we leave will be due to problems with the actual house? And does that even matter when she will be selling it?
