Re: Termination of tenancy agreement at [your address]
As required under section 97 of the Residential Tenancies Act 2010, I am writing to give you 21 days notice. I will be giving vacant possession of the above premises on [date].
I will be in contact with you closer to this date to arrange a time when we can both inspect the premises, complete a condition report and I can return the keys to you.
