    Is there any reference for the definitions of these improvements?  Primarily the difference between mid-range and upscale?

    Yes, if you select a particular improvement you will see its definition. For instance, if the home has a mid-range bathroom remodel, the Hanley-Wood data assumes that the project was something like this:

    "Update an existing 5-by-7-foot bathroom that is at least 25 years old. Replace all fixtures to include 30-by-60-inch porcelain-on-steel tub with 4-by-4 ceramic tile surround; new single-lever temperature and pressure-balanced shower control; standard white toilet; solid surface vanity counter with integral double sink; recessed medicine cabinet with light; ceramic tile floor; vinyl wallpaper."

    If the home has an upscale bathroom remodel, the work is assumed to be along these lines:

    "Expand an existing 5-by-7-foot bathroom to 9 by 9 feet within existing house footprint. Add another window bringing total glazing area to 30 square feet. Relocate and replace tub with custom 4-by-6-foot dual shower with top-of-line fittings and full-body-wash shower wall, tile and glass block surround, glass door. Relocate toilet into a partitioned area and replace it with a one-piece color unit. Add bidet. Add medium-range stone tops in custom vanity cabinet with twin designer undermount sinks; polished nickel faucets. Add linen/towel storage closet. Ceramic tile floor, papered walls, hardwood trim. Add general and spot lighting and a humidistat-controlled exhaust fan."
