6 Worst Home Upgrades For Your Money : #6

Upscale Garage Addition

Instead of cleaning out the garage, how much would you pay to have a new one built from scratch? This time, it would have all the organizational built-ins, and a durable, easy-to-clean floor to ensure it would never be messy again. And windows for natural light. Oh yeah, and you could store a couple of cars in there, too. The price tag for a top-of-the-line detached two-car with all the trimmings is about $90,053, according to the report. You can expect to recover about 53.6 percent of that when you sell.

"This one is completely decked out on the inside," says Alfano. "It's a dream garage."

And that's likely some of the problem with recovering the value at resale. Says Keim, "You've got a very small target audience out there that wants an upscale garage."
