Most for sale homes will receive a daily tidy at 10am - this is to ensure that the home looks tidy and presentable at all times for viewings. (N.B. Some homes will not receive daily tidies, this is usually due to low frequency viewings or the home being sold). These homes will receive a tidy at 10am, only in the event that a viewing is booked in and guests will be notified beforehand.
Therefore, there are TWO sets of messages which are different based on whether homes are being cleaned daily or only in the case of a viewing.
These are sometimes referred to as 'DVT'
