I have learned that there are tricks to having people think you are a clean freak, without dedicating your life to cleanliness. The most important things to remember are extra bedrooms, crawl spaces and the garage don't count in cleanliness tests. They are like the FREE spot on a bingo card. Simply toss all of your junk into one of these FREE zones, and make the rest of your house look less cluttered, and cleaner. Be sure you can still close the door though, as falling debris can pose a hazard, which brings up our next tip.

My aunt used to have elaborate turkey dinners, which we often attended. She had obviously cooked all day judging from the number of courses, but when we sat down to eat dinner, the kitchen counters were clear. No pots or pans or mixing bowls. Just the beautifully presented platters and a spotless counter. She is a professional cheater.
