One of the biggest and most noticeable differences between a track/starter home and a custom home are their trims and moldings. I find this is the last thing homeowners want to upgrade. I don't blame them since many builders charge a lot for this upgrade. Many homeowners end up repainting with colors, faux textures, and glazing to upgrade their home. While all these do wonders to a house finished in the standard builder's color (beige) they look tons better next to more dramatic moldings.
