If you already keep a clean house, simply keep up the good work, checking to make sure you don't overlook little-used closets and other nooks and crannies that aren't part of your weekly routine. This needs to be a deep cleaning.
For the rest of us, it's time to get serious. Start at the top (the attic or second-story rooms) and work your way down. Clean ceiling light fixtures first, scrub walls and woodwork and finish with floors. As you work your way from top to bottom, don't leave one area until it is completely clean and then move on. Don't drag dirt from one area back into the place you just cleaned.
Finally, don't underestimate the power of clean windows. Buyers won't walk in and think, "Wow, clean windows!" But, freshly cleaned windows look great from the outside and with the lights on, they sparkle on the inside. And with this method, window cleaning is not all that bad.
Rearrange Your Furniture
Your furniture is arranged the way it best suits you and your family. When you're staging your home to sell, you'll need to use your furniture as marketing tools to help create inviting vignettes.
Avoid having furniture lined up along the walls. Pull the sofa away from the wall and pull chairs close to create a conversation area. Also, you may need to remove some furniture so it's easy for people to walk around in the rooms. If you've toured model homes and had the feeling you could move right in and live there, that's what you're going for.
As Andy Dwyer once said, 'Windows are the eyes to the house.' If your windows are covered with heavy drapes, flouncy curtains and/or clunky valances, take all that stuff down. You want every possible ray of natural light coming in through your windows. Most people want shades or blinds to provide privacy, with as little obstruction as possible. If you have shades with a broken lift cord, here's how to fix it.
