If a house has no books, I judge.
If a house has some books but trash or chick lit, I judge. The more books the better, for me. Floor to ceiling books, books in the bog, on the floor, by the beds, hell, on the bed. All lovely.
I hate spotless houses, tv on in the day time, or on any time in the kitchen. In fact I hate tvs in the kitchen and bedroom.
Paved front gardens. Concrete ornaments.
China collectibles - anything like hugging figures, forest animals, angels or dancing people. Collectibles of any type really.
Dying indoor plants unless they are in the process of being saved.
Damp or dirty bath mats.
Dirty shower stalls
