It costs as little as $10 or $20 to fix.

If you're in the process of selling your home, you're likely thinking about the big things: Finding the right realtor, renovating the primary bathroom, sprucing up the kitchen. The list seems to go on and on.

But here's one thing you may have overlooked before listing your home: Making sure all of your electrical sockets and light switches have plate covers (preferably nice looking ones, while you're at it). "One of the funniest—and most annoying—requests I get is for sellers to replace missing cover plates on light switches and outlets," Amy Berglund, a real estate agent with Re/Max Professionals City Properties in Denver, Colorado, tells in a recent article on small, surprising things that can delay a home sale. "Usually they're missing in places such as laundry rooms and basements—think places that aren't used that much. It is an incredibly affordable fix."

Each cover plate ranges from a few dollars to $20, making it a tiny dent in the budget and a small price to pay for something that people really notice when touring your home.

Best of luck with selling your home, everyone. Remember, a journey of 1,000 steps starts with a single socket cover.
