Declutter Some More!
A good rule of thumb is 'Reduce by 50 percent.' In other words, if you have 10 things on a shelf, put away (or get rid of) five. If there are a dozen mugs on display in the kitchen, lose six.
One more thing: If you have a lot of personal items on display, it can make it harder for potential buyer's to imagine themselves living there. If you display items of a political or religious nature that could be off-putting to others, consider putting them in storage until you can proudly display them again in your new home.
If you decide to do some interior painting, stick to neutral colors. You've heard it before, but it's the truth. Neutrals don't distract and they allow potential buyers to imagine their things in your home. If you'd like some guidance on choosing colors, check out this collection of tips.
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.
