First impressions count. When potential buyers approach your home, curb appeal sets the tone. But the moment they step inside, another powerful sense takes over — smell. Imagine being greeted by the gentle scent of fresh flowers versus the musty odor of mildew or cigarette smoke. The difference is striking — and can make or break that all-important first impression.

A recent online discussion among homebuyers revealed that many walked into a showing and immediately turned around — not because of décor or lighting, but because of unpleasant odors. From stale smoke to pet odors or musty basements, bad smells can send buyers running before they’ve even looked around.

The Connection Between Smell and Memory

Scent is deeply tied to memory and emotion. When buyers tour several homes in one day, a pleasant or neutral scent can leave a lasting impression. On the other hand, a foul or overpowering smell can linger in their minds — for all the wrong reasons.

According to research from Harvard Medicine, the brain’s hippocampus links smells to emotional experiences, storing them for years. That means a single scent can instantly bring back feelings tied to a specific moment. Buying a home is an emotional experience — so you’ll want the emotions tied to your home to be positive ones.

Keep It Neutral

Lighting, staging, and cleanliness matter — but so does the air your buyers breathe. While it might be tempting to use your favorite candle or essential oil, remember that everyone’s preferences differ. To appeal to the widest audience, stick with light, neutral scents — or go scent-free.

A simple trick: open windows 30 minutes before a showing (weather permitting) to let in fresh air. Avoid strong air fresheners, heavily scented candles, or oils that can come across as attempts to mask odors. Empty all trash bins, including those in closets, bathrooms, and laundry areas, and make sure every space smells clean and fresh.

Focus on Bathrooms & Kitchens

These two rooms get the most attention during a showing — and often harbor the toughest odors.

Bathroom: Keep it clean, dry, and well-ventilated. Remove used towels, mats, and laundry. Freshly washed linens or none at all work best. Avoid moisture buildup that can lead to mildew or musty smells.

Kitchen: Before showings, take out the trash, wash and put away dishes, wipe down countertops, and check appliances like the garbage disposal and dishwasher for odors. Declutter and make sure the space feels fresh and ready for use. Even a small amount of leftover moisture or food waste can create unwanted smells.

For Pet Owners

We love our pets, but not everyone will appreciate their scent. Before showings, take pets out if possible, vacuum thoroughly, and remove pet hair, beds, toys, and blankets that may trap odors. Clean food bowls and litter boxes — or tuck them out of sight. Even subtle pet smells can be a dealbreaker for sensitive buyers.

Other Sneaky Odor Sources

Some smells are less obvious but equally off-putting. “Old house smell,” caused by stale air or dust, can make buyers assume there’s an underlying problem. Regular cleaning and ventilation help minimize it.

Cooking odors — especially from garlic, onions, or spicy dishes — can linger for days. Try to avoid strong-smelling meals before showings. The same goes for laundry rooms, garages, and basements. Wet clothes, cleaning products, and chemicals can all create odors that distract buyers. Keep these spaces clean, dry, and well-aired.

Final Thoughts

When selling your home, remember that buyers use all five senses — and smell is one of the strongest. You don’t need to make your home smell like a bakery or a spa; it just needs to smell clean, fresh, and inviting.

Before every showing, open the windows, tidy up, and take a “smell test.” If possible, ask someone with a fresh nose to give honest feedback. Sometimes, that subtle hint of freshness is what transforms a visitor’s “maybe” into an enthusiastic “yes.” 🌿
