Photos - As a seller, you need the best photos possible, so having a professional photographer is a must. Bad pictures will turn people away from even looking at the home in person.
Lack of Curb Appeal - Update the curb appeal as much as possible. Buyers will drive by and if the curb appeal isn't to their liking, they won't waste their time to go inside.
Too Much Clutter - If there is a lot of clutter, when others go in the home they may believe there is little to no storage since "stuff" is everywhere. Clutter just turns people off in general.
Price - Making sure the home is priced right from the beginning will help it to sell faster and potentially keep more money in the seller's pocket.
Choosing the Wrong Agent - Having an agent with experience, who knows the local market and who has great marketing tactics for your home is a must. Choosing an agent that isn't good in all of these areas can certainly hurt the sale of the home.
