First impressions are everything – at least when it comes to selling your home. According to the National Association of Realtors, 63 percent of homebuyers will drop by after viewing a home they like online. What will they see? The home's exterior – including the front entry, yard, driveway and sidewalk -- should serve as a snapshot of what's to come when potential buyers enter your home.

1: Curb Appeal Starts Online
Since 88 percent of homebuyers begin the process on the Web, fabulous photos are critical to getting homebuyers to the front door, says Jennifer Ames, a top Chicago real estate agent. Find the best time of day to shoot each room. Take a digital shot and examine it as if you were a buyer, and get rid of extras – bikes on the front porch, platters stacked on top of the fridge – that don't show your home at its best.

2: Act Like a Buyer
Walk around your entire home's exterior with a critical eye and a notepad and pen. Take notes on what looks "off" and needs repairing, replacing or cleaning. Get in your car and drive by slowly from both directions during the day and night. You might see something you've never noticed before, like a Frisbee on the roof or a missing piece of siding.

3: Look Up to the Sky
Most homeowners don't give their roofs a second glance, but the roof is an important curb appeal item that buyers do notice, says Jean Miskimon of the Metal Roofing Alliance. Is yours missing any shingles, or is it dingy and streaked? A good cleaning or, if necessary, a roof replacement will up your home's curb appeal factor tremendously.

4: Shiny, Happy Numbers
If your house numbers aren't easy to see or if they're dirty and dingy, replacing them carries a tremendous impact, Caroline says. Consider the style of your house – traditional, transitional or modern – and create a harmonious or contrasting effect with new house numbers.

5: Get a Second Opinion
Homeowners often get used to certain defects –chipped paint on the front door from the keys banging against it, cobwebs on the porch ceiling, cracked or stained steps – and might need a new set of eyes to help them prioritize what needs to be fixed and cleaned up, says Kelly O'Ryan, office manager for Coldwell Banker in Lexington, Mass. "Know your budget and how much time you can spend, and get an outsider to help you decide what needs work," she says.

6: Under Pressure
Budget-conscious homeowners will love this tip: Pressure-washing the dirty siding and deck, as well as the oil-stained driveway and faded walkways is an extremely cost-efficient way to increase your home's curb appeal. If you don't own a pressure washer, you can rent one from your local home improvement store for the day.

7: Plant Some Color
Except for the dead of winter, some types of annual plants are always in bloom, says Sheri Silver, a landscape designer and owner of Fiori Garden Design. "Spruce up your porch containers, window boxes and front beds with some colorful flowers for instant lift," Sheri advises. Never plant artificial flowers – a few inches of dark mulch will brighten up the beds without screaming "fake."

8: Open Up
Fling open the shutters, curtains and blinds, Paul says. "Homes that are brighter inside sell faster, and open curtains look prettier on the street," he says. Go outside and look at your window treatments from the street, and try to keep a uniform look throughout.

9: Light Up Your Landscape
Give your walkway an edge with solar light fixtures, which are affordable and a cinch to install, says Rick Hoffman, president and COO of Coldwell Banker Residential Brokerage of San Diego County and Temecula Valley. "Solar lights are inexpensive, and you can place them where they highlight your home's best attributes – landscaping, walking paths and any custom fixtures."

10: Add Some Polish
Paint is only about $25 per gallon, and painting the front door, trim and shutters is a great way to polish the look of your home, Kelly says. Other inexpensive fix-ups: a new mailbox (research your city's regulations to make sure you're up to code first), a new porch light fixture and a cheery new welcome mat.
