We get calls all the time from homeowners who want to pick a paint color before they move in. I get the logic. Why not arrive to walls with a fresh coat of paint. Of course you can do it this way, but in my opinion it is not ideal. There are thousands of paint colors with various tints, tones and shades. And each one looks different from home to home, because light sources vary, meaning what looks good in your current home might not in your new one. You want the color that best complements your upholstery, artwork, rug and whatever else. You can pick that color only if your stuff is actually inside your home.
