At what point do buyers expect the garage to be another decorated room?

I'm used to explaining to homeowners that their garage needs to be clean, neat, as empty as possible of unnecessary storage items and randomly placed shelving and hooks.  Rarely do I run across a garage that doesn't have painted drywall, but sometimes the taping is loose and needs to be fixed.   The Rorschach Test oil splotches that the homeowners have become accustomed to obviously need to be cleaned up.  Ant, roach and mouse traps need to disappear-and fast.  Any signs of old leaks or water damage need to be addressed, primed and painted.  Weird wiring, hanging chains and other question marks need to be eliminated. The space needs to be able to hold cars. This is the minimum that any homeowner should do, in my opinion

Buyers don't expect to see painted floors or garage flooring in this stage of the game unless you are talking about higher end homes.  As the cost of storage systems and floor options comes down, more and more homeowners will go for the look and consequently buyers will come to expect it as they do finished and furnished basements.  HGTV shows and ads are pushing these "Man Spaces" with refrigerators, TV's, ambient and task lighting and more. They are wonderful to look at.  Is this space a stager's final frontier?

There is no doubt that a home with a "garage makeover" will have an appeal and it will definitely stand out in the market of similar homes.  It may be over improvement in some, depending on the expense and detail.  It won't necessarily warrant a higher price on a home, but in a slow market it may just be that extra edge.

So what's next, staged attics?
