Why would you bother hiring an Interior Decorator to work on your home when you are just putting it up for sale? The reason why is, because by putting a little money in on your end can increase the value of the home or make it more appealing at a slightly higher price in which you can get most if not all of your decorating investment back.
It is always good to get a consult from an interior decorator that specializes in "home staging". That is simply the investment of putting money in the house to get more money out of the sell. Get a consult and see what they suggest. It could be something as simple as a new coat of paint, change of color scheme or possibly working with the furniture to make the aesthetics of the room showw more value.
There are a lot of elements that can help make your house not just another house on the market. Instead, it can become the house that has offers rolling in and you find that that simple investment has made you even more profit on that glorious home of yours.
