When you decide it's time to sell your home, what you do or don't do to get the place ready for the market will determine whether potential buyers come flocking or go fleeing.

Face it: Your house may have some icky issues. And if you don't address them, you'll have fewer showings and get fewer offers.

Here are the 10 biggest buyer turnoffs and how to avoid them.

1. The place looks hideous from the street

Your house had better have some curb appeal.

You’ve driven by the front of your house so many times that you barely take notice. And unfortunately, once you decide to sell, most of your focus will be on the interior, not the exterior.

Huge mistake, according to Cindi Hagley, broker/division manager with The Hagley Group in Pleasanton, California.

"I've had buyers in my car, when we drive up to a house, who don’t even want to go in because of how crappy it looks. It could be a dead yard, debris in the yard or a crappy door," she says.

Solution: Improve your curb appeal. Mow like you mean it, and buff up that door!

2. Your decor could make buyers scream

Before you let them show your home, you might want to put your bobblehead collection away.

To cast the broadest possible net for buyers, it's smart to strike wall displays, posters and other visuals that could offend.

That might mean anything from a nude sculpture to a banner celebrating your favorite NFL team. A Hillary Clinton bobblehead is as much of a danger as a signed, showcased copy of "The Art of the Deal."

"Any décor that may be controversial or sensitive to others, such as political memorabilia, military or religious icons, tend to turn people off," says Julie Dana, The Home Stylist in East Aurora, New York.

Hagley agrees: "If you have one culture that does not embrace another culture, it can be a deal-killer."

Solution: Keep it neutral and upbeat or delete.

3. Your home has dings, cracks and defects

Hey homeowner, your crack is showing.

As a homeowner, you've lived with a number of household flaws and mechanical nuisances so long that you no longer notice them. Unfortunately, prospective buyers will.

"One of the biggest things that turns off buyers is any maintenance that needs to be done," says Dana, who's also the co-author of The Complete Idiot’s Guide to Staging Your Home to Sell.

"If right away, in the first few seconds of seeing the house, those potential buyers are starting a chore list, the sale is gone," she says. "It could be anything from cracks in the wall to a loose doorknob."

Solution: Fix them. Now.

4. That wall-to-wall carpeting has got to go

A buyer won't want your old wall-to-wall carpeting.

Depending on your locale, wall-to-wall carpeting can vary from being a mere annoyance to a deal breaker.

"It's a small turnoff if the carpet is in good condition, especially here in California where buyers who walk in are going to put their own touches on it anyway," says Hagley.

But house shoppers will be curious about what they can't see. "I would be more concerned with what’s under that wall-to-wall carpeting," she says. "Is it hardwood that just needs to be refinished or something else?"

Solution: Roll the dice but be prepared to compromise.

5. To be honest, your place might stink

A buyer might think your house needs a deodorant.

As visual as the house-hunting experience tends to be, there’s another overriding sensation that can literally stop a walk-through at the front door.

"Urine smell from a pet is probably the single largest turnoff there is!" Hagley gasps.

"In fact, I will not list a home that has a pervasive odor of any kind, because it’s senseless and it makes the Realtor look asinine," she says.

Solution: You’ve been warned.

6. That popcorn ceiling looks so last century

Your ceiling looks like stale popcorn now.

Once hot, popcorn acoustic ceilings now are not. Mostly because they’re a major hassle to repair.

"If it's an entry-level home and you’ve got an excited buyer, that's not going to be a big deal," Hagley says.

"But," she adds, "if you're dealing with a $1 million-plus home, that is a huge deal. In California, you would write into the contract to eliminate that."

Solution: Prepare to bargain, or not. After all, it didn’t stop you from buying, right?

7. That's not a color scheme, it's a conspiracy

A buyer may not be wild about your wild color choices.

Whoever observed that beauty is in the eye of the beholder didn’t have to convince Terry Cannon, broker for Oregon Exclusive Buyers Realty in Salem, Oregon.

"We had one showing that had black tile throughout the whole bathroom, the bedroom was all dark, and it had a spider web painted on the ceiling," he chuckles. "Why would they do that?"

Know upfront that the wallpaper you love and that Candy Crush-themed children's bedroom will not help sell your home.

"Especially female buyers — they'll just turn around and walk right out," says Hagley. "A good Realtor is going to go in and neutralize the home if there's something like that."

Solution: Gray tones are nice.

8. You or your renters need to scram

It's not your job to help show the home -- so get lost!

"The absolute worst" is how Hagley describes sellers who insist on hovering.

"And not only are they there for the walkthroughs and the initial showings of the home, but if they insist on being there for inspections, that's not good," she says. "That is going to be a pain in the butt to sell, period."

In Cannon's view, renters are just as bad, if not worse.

"There are some homes that you just can't get into because the renters don’t want to show the home," he says. "Even though they know we're coming, they leave it such a mess that it's just a disaster inside."

Solution: Vacate for all showings, take your pets with you, and instruct your renters to do likewise.

9. Your home doesn't look like the photos

Does your house really look THAT good?

House-hunting online at Realtor.com, Redfin, Trulia, Zillow and related sites will quickly school you in the not-so-subtle art of real estate photography.

"You can find an angle in any kitchen that makes it look like a million-dollar home. I don't see anything wrong with that," says Hagley. "However, you also have to be careful; you don’t want to misrepresent."

True story: The online curb shot of the home my wife and I bought two years ago showed nearly a half-acre of vibrant green grass, which, upon arrival for our walkthrough, was an equally-impressive stretch of Florida sand.

Only later did I notice the disclaimer beneath that online shot: "Lawn courtesy of Photoshop." We purchased the home nonetheless, and today the lawn is grass-green.

Solution: Don't set your listing up for failure by misrepresenting it in photos.

10. It looks like a home on 'Hoarders'

That clutter will make it tough for a buyer imagine what's underneath.

Clutter can become a major obstacle to living in, much less selling, a home.

As Hagley points out, a cluttered house instills far deeper fears in many homebuyers than where to pile the laundry.

"If your home looks like a mess, are you taking care of it for maintenance? What do your gutters and roof look like? What might you be hiding with clutter?" she wonders.

Those aren't questions you want to inadvertently pose to potential buyers.

Solution: Thoroughly clean the manse before showing.
