First impression is everything so make sure that your curb appeal is spot on! Pull weeds, freshen up the flower beds with new mulch and pretty flowers, hang a nice wreath on the front door, and layout a fresh, clean, welcome mat. The potential buyer will already have a great impression before they even enter your home!
Second, you will want to depersonalize and declutter. Less is more so box up all those nick knacks and the million pictures of your kids & grandkids. They are cute but you want for the buyer to be able to envision themselves in the home.
Third, touch up time. Time to patch any holes in the walls, touch up the paint, and address that old moldy caulk around the tub. It is important that the buyer feels confident that your home has been well maintained and cared for.
Fourth, is clean up. Now is the time to get down on your hands and knees to scrub those baseboards and floors. It's also time to look up in the corners for any cobwebs and be sure to dust fans, light fixtures, and return air vents.
Fifth, smells are also important so consider a plug in or wax melts but something that is light and subtle as some people are sensitive to smells so you do not want for it to be overwhelming.
