Give observations a structure
A property visit produces many impressions in a short time. A bright room, a difficult corner and an attractive view may be remembered more clearly than storage depth or the route between rooms. A viewing notebook could help retain those ordinary details without turning impressions into professional findings. Record where an observation was made and the conditions at the time. A quiet room during one visit is an observation about that visit, not proof of permanent quiet. The distinction makes a later conversation more precise and reduces reliance on a vague overall feeling.
