What type of home did you live in when you were growing up? A townhouse? A single family home? A one-story home? A two-story home? A home with (or without) a basement?
The home you lived in as a child might be subconsciously impacting how you think about and feel about homes you might buy as an adult.
If you grew up in a single level home you might be most comfortable buying a single level home -- and bedrooms might seem *SO* far away in a two level home.
If you grew up in a two level home you might be most comfortable buying a two level home -- and it might feel odd to have *EVERYTHING* on the main level in a one-level home.
If you grew up with a basement it might feel like something is missing in a home without a basement.
Certainly, if you grew up in multiple homes of multiple styles and sizes when you were growing up, the impact of those childhood homes might be more diluted.
