Marketing a home involves understanding and dealing with the whole picture. There may be many other factors that would positively impact the sale of your home. Curb appeal, condition of the kitchen and bath rooms, colors, interior decorating etc.
Basically any improvements you can make could make a difference in the sale ability of your home. But there could be more to it than just the floors.
In general Clean makes homes look more inviting and bright makes them look larger....
So depending on what the condition of your current floors is a much better suggestion could be made.
Also remember, if you change a large area like the flooring, once that is brand new the rest may not look so good anymore.... and then you will start with the floor, follow with painting, new hardware, new window treatments etc. etc.

When you are acting as a buyer looking for a home which properties can you see yourself in? Do you prefer homes with projects just waiting for your special touch or are you like most of us who want it fresh and clean in move in condition?
Go to some open houses with the mindset of a buyer to see what makes you want to put an offer on a home. With a critical eye, take another look at your property. We all tend to become accustomed to the little things in our homes that make them seem dated so we over look them. Buyers often are unaware of what makes them choose one comparable home over another. Many of the reasons are subliminal.
By renovating in good taste you maximize your audience. Be judicious about the costs of your updating and you will be pleasantly surprised with the outcome in most markets. The buyers will only see the "after" so they won't know how much you've put into it. Small things can mean so much. Change all the hardware on your front door. New moderately price fixtures in the kitchen make it all seem so much cleaner. New hardware on the cabinets that are the current trends make the entire room feel newer. Replacing light fixtures with today's look is very effective. Little tweaks can make all the difference.
Best of luck,
