For homeowners, selling is hard enough in today's market given the lack of interested and qualified borrowers. To make matters worse, many sellers continue to make mistakes that could cost them a promising deal or even deny them any offer at all. Avoiding the following mistakes can help keep you from shooting your home sale in the foot. Here are nine potential seller mistakes and how to avoid them: Mistake No. 1: Skipping the home prep. Buyers want to see a house as flawless and depersonalized as possible, so sellers need to take care of every repair, declutter their home and add some curb appeal. Video:Staging your home before you sell "Buyers want to know their stuff will fit in the home with room to spare, so if you shove everything into the garage or into one closet and it's overflowing, they will be turned off," says Angelica Delboy, a Realtor with Re/Max Gateway in Lorton, Va. Lee Lamont, a Realtor with Coldwell Banker Residential Brokerage in Dallas, says sellers need to keep their home "pitch-perfect" with landscaping trimmed, dishes done and beds made every day. "It takes 60 seconds for buyers to form an opinion about a house and everything else after that becomes positive or negative reinforcement of that opinion," says Lamont. Mistake No. 2: Overpricing your house. Delboy says sellers need to price a home according to its condition and the local market and realize it must appraise at the sales price.
