Showcase the Interior
Check the pictures you took of the interior of your house and identify what looks shabby. As a general rule, clean things first. If a good cleaning job doesn't greatly improve the appearance, paint, seal, or polish.
To make your interior look neat and clean, the first thing to do is get rid of clutter, junk, and damaged or broken items. If you see an item and ask yourself “why is this on my shelf when I wouldn't pay 10 cents for it at a garage sale,” it's time to part with it. Getting rid of things is one of the hardest jobs, but you will find it easier to start now than when it is time to pack. Use logic. If you have user manuals to products you don't even own anymore, get rid of them. If you've been hanging on to socks without mates, now is the time to toss them. Throw away all broken or otherwise useless items. Making those crucial decisions about what to keep and what to toss will be easier if you recruit a friend to help.
It's undisputable: Clutter will detract from the appearance of your home. You may really love to cover every available surface with knick-knacks, but potential buyers want to see your home—not your belongings. Keep a few picture frames, books, and other colorful or interesting items on display, but make sure items look organized and neat.
Once you've gotten rid of unwanted junk, the next way to brighten up your home is to do a thorough cleaning. Clean all the windows, inside and out. Take down drapes and blinds for a thorough cleaning of them as well. Scrub the hard surface floors and the baseboards. Vacuum the carpeted areas. If the carpet has not been cleaned recently, have it professionally cleaned or rent a steam cleaner and do it yourself. Wash all the cabinet faces and clean all the mirrors. Finally, don't forget about the ceilings! Few visitorslook up at the ceilings in a home, but buyers might. Clear away all cobwebs and give ceilings a good wipe-down with a damp cloth. This will brighten up a dingy room.
