Seller Mistakes That Cost Thousands (But Cost Under $100 to Fix)

This week, our agents walked through two homes that were both listed for sale. Both homes were hot inside. Not warm. Hot. The kind of hot where you start sweating within a few minutes of walking through the front door.

Neither home had a broken air conditioner. Both systems worked fine. The sellers had simply turned the thermostat up to save on their electric bill. In dollar terms, they were saving maybe $20 to $30 a month.

Here is the problem. A buyer walking into a hot house does not think, "the seller is saving on utilities." They think something is wrong. Is the AC too small for this house? Will it struggle to keep up in July? Is there a hidden repair coming? Their brain starts building a list of worries, most of which are not even true.

On top of that, there is something buyers feel but cannot always explain. It is hard to picture yourself living somewhere, relaxing in a room, enjoying a kitchen, when you are uncomfortable and just want to leave. People like to think they make decisions with logic. In reality, most of us react emotionally first and explain it with logic after. A buyer who felt hot and rushed through a showing may walk away and simply say, "I did not love that house." They may never connect the dot back to the thermostat.

The math does not favor the seller here either. Carrying a home on the market, covering the mortgage, taxes, insurance, and utilities, commonly runs between $2,000 and $6,000 a month depending on the home and the local market. A seller trying to save $30 a month on electricity, while quietly pushing buyers away and adding days on market, is often losing far more than they are saving. A home that sits an extra month can end up costing thousands once you add up carrying costs and the price cuts that tend to follow a stale listing.

The fix: Set the thermostat to a comfortable temperature before every showing and every open house. In the summer, that usually means the low to mid 70s. It costs a few extra dollars on the power bill. It is one of the cheapest, highest-impact things a seller can do.

Smell is one of the fastest ways a buyer forms an opinion about a home, and it happens almost instantly, often before they have even finished walking through the front door.

Common smell issues sellers do not notice in their own home:

Sellers get "nose blind" to their own home because they smell it every day. A buyer walking in for the first time does not have that filter. And here is the part that surprises a lot of sellers: covering a smell with a strong candle or air freshener often backfires. Buyers tend to notice the cover-up and start wondering what smell is being hidden underneath it. A heavy fragrance can raise more red flags than the original odor.

The fix (all under $100 combined):

Skip the heavy candles. If you want a light scent, use a natural spray like Febreze Natural instead of something overpowering. A clean, neutral, well-ventilated home almost always beats an artificial scent.

Willing to spend a little more? A few upgrades cost more than $100 but are worth knowing about if smell is a bigger concern. Cleaning your air ducts can remove trapped odors that linger in the system. Removing drapes and curtains helps too, since fabric window treatments absorb smell over time and are easy to overlook.

As much as buyers love animals, showings go smoother when pets are not in the home. A barking dog can make it hard for buyers to focus, and a dog left loose in a garage or behind a door can startle someone or, worse, get out and bite. That is a liability issue for the seller, not just an inconvenience.

Pets also add to the smell factor covered above, and some buyers are simply not comfortable around animals, even friendly ones. If you cannot take your pet with you during a showing, ask a friend, family member, or your agent to help arrange a place for them to stay for a few hours.

The third mistake is one of the most common, and one of the easiest to fix: too much personal decor.

Family photos on every wall. A large collection of sports memorabilia. Deer heads or trophy fish mounted in the living room. None of these are bad in a home you plan to keep. But when you are trying to sell, they work against you.

Buyers need to picture their own life in a home. That includes their own furniture, their own photos, their own routines. When a space feels heavily personalized to the current owner, it becomes harder for a buyer to make that mental leap. National housing data backs this up directly. According to the National Association of Realtors 2025 Profile of Home Staging, the large majority of buyers' agents report that staging and presentation directly shape how buyers view a home, and most confirm it helps buyers picture themselves living there. A home packed with someone else's personality makes that harder to do, even if the buyer cannot quite explain why they feel less connected to the space.

The fix:

While you are working through the list above, a few other low-cost items are worth a quick pass through the house:

Light bulbs. Replace any burned-out bulbs and try to keep the color temperature consistent room to room. A dark room feels smaller and less inviting, and inspectors sometimes flag it as a possible electrical issue when it is really just a bulb.

Cobwebs and dust. Ceiling corners, fan blades, and light fixtures are easy to miss but easy for buyers to notice.

Curb appeal. Coil up hoses and edge the lawn. Skip seasonal decor in your listing photos altogether. A Christmas tree or fall wreath in the background is an easy way for buyers to tell a home has been sitting on the market for a while.

Fresh touches. A layer of fresh mulch in garden beds, a pressure or soft wash on the siding, walkways, and windows, a new doormat, and a couple of flower pots near the entry all go a long way for very little cost.

Clutter. Clear countertops, entryways, and floors. A cluttered room reads as a smaller, less cared-for room, even when the square footage is the same.

None of these require a contractor or a big budget. Most can be handled in a single weekend.

Every seller has heard that first impressions matter. What is easy to miss is how much those first impressions are actually worth in real dollars.

National data supports the idea that presentation changes outcomes, not just opinions. The National Association of Realtors 2025 Profile of Home Staging found that nearly half of sellers' agents observed shorter time on market for homes that were staged and presented well, and close to three in ten agents reported staged homes received meaningfully higher offers. On the flip side, industry data on carrying costs shows that an extra month or two on the market commonly adds several thousand dollars in mortgage, tax, insurance, and utility costs, often followed by a price reduction once a listing starts to feel stale to buyers watching it online.

Here is what that looks like locally. The average home price in the Greenville area this year is around $405,000. Homes that are staged well and priced right typically sell in two weeks or less, for 97% or more of their asking price. Homes that skip these steps often sit for 60 days or longer and tend to sell for closer to 93% of asking price. On an average priced home, that gap works out to about $20,000 less in the seller's pocket. Add in the extra mortgage payments, taxes, and utilities from sitting on the market longer, and the total cost can climb past $25,000.

Put simply: the sellers who spend a little time and under $100 fixing the temperature, the smell, and the personal clutter tend to sell faster and for more money than the sellers who do not. The ones who skip these steps are not really saving money. They are usually just spending it more slowly, in the form of extra mortgage payments and lower offers down the road.

Does the temperature really affect whether a house sells? Yes. A home that is too hot or too cold makes buyers uncomfortable and rushed during a showing, which affects both their practical impression of the home and their emotional connection to it. It can also raise unnecessary questions about whether the HVAC system works properly.

What smells should I avoid when selling my house? Pet odor, smoke, strong cooking smells, and musty or damp smells are the most common deal breakers. The safest approach is to eliminate the source of the smell and ventilate the home, rather than covering it up with a strong air freshener or candle.

How much should I spend preparing my house before listing it? Many of the highest-impact fixes cost under $100 total. Setting the thermostat correctly, deep cleaning, airing out the home, replacing light bulbs, and packing away personal items make a bigger difference for most sellers than expensive renovations.

Should I remove all personal photos and decor before listing? Not all of it, but most of it. The goal is to help buyers picture their own life in the home. A few tasteful, neutral touches are fine. Heavy personalization, large collections, or highly specific hobby decor tend to make that harder for buyers.
