How much is a bathroom worth?

Economists are now applying econometrics to the time-honored questions of real estate. Based on a sample of 29,000 sales, and a proper set of statistical controls, the researchers derived an extensive set of valuations. The numbers given express the percentage change in the value of the home:

1. A full bathroom: 24 percent
2. A water view: 8 percent (I would have expected more)
3. Waterfront location: 18 percent
4. View of a golf course: 8 percent
5. A garage: 12.9 percent
6. A tennis court: 3.1 percent
7. In-ground sprinkler systems: 8 percent (surprisingly high)
8. An in-ground pool: 7.9 percent
9. A separate laundry room: 15 percent (surprisingly high)
10. An above-ground pool: minus 2 percent.
11. Is your house a "fixer-upper"?: minus 23.6 percent.

Here is a summary table of the results. Here is original research. Here is a Washington Post story.

Many of these amenities sell for more than what they cost to install. So the bottom line here supports the conventional wisdom of the trade. People don't fix up their homes enough before selling them.
