Dear Mr Nixon,
Thank you for your letter dated 6th September.
We would like to advise that by withholding your rental payment you are in fact in breach of your tenancy agreement and would therefore request that payment be made without delay.
Further more we would like to advise that we have instructed a damp specialist company called Atlas Timber to contact you directly for an appointment to visit the property and investigate the problems you have reported and then come back to us with their findings.
We have informed the landlady of the above and also copied your letter to her. Your landlady has asked us to highlight to you that she made if very clear before the tenancy commenced that she was not in a position to offer any redecoration but did fact accept a much lower rental to reflect this. She has also confirmed that she has given her permission for you to decorate the flat at your own expense providing the colours are kept neutral and the work is done to a professional standard.
Your landlady has confirmed to us that she would be happy to release you from the contract immediate effect should you wish to vacate. If this is the case please confirm in writing to us.
