Housing plot classes

Location basically. Seems like proximity to aetherytes, market boards, and summoning bells plays a factor, as well as where it's located on the map (edit: should say that 'better' grades tend to have better views.) At least this is what I noticed back when I was looking for the location I wanted to get my house at.

Thats what I thought too, but sometimes I see houses (like mine) that are first class and tbh they dont seem first class at all, the MB is not that near, the view is terrible too, so I was wondering that.
