Sally, you need to remember that once you put your house on the market it is no longer your home but a product for sale. If you can't afford to hire a professional to help stage your property there are a few things you can do. You need an objective point of view, perhaps your Realtor or a friend to take a good honest look at your house. Look at things through a potential buyer's eyes. They need to be able to see themselves living there. Declutter, declutter, declutter! Best of luck!
You will have a limited group of buyers that is interested in your style of house. I would consider consulting a professional stager in your area. A consultation is very affordable and will give you a detailed list of recommendations in order for you to complete the work. Your house needs to look its absolute best in order to attract a buyer from your already limited pool. Best of luck!
