11 things that make a home unsellable, according to realtors

Several realtors said that when a home isn't selling, it's probably because the price is too high.

"An unsellable home is one that is not priced right," said Noemi Bitterman of Warburg Realty, who handles sales in New York City for homes between $500,000 and $1.75 million.

Several realtors cited bad odors as a common reason for why a home won't sell. Three agents noted that odors from cats in particular are bad news.

Residual scents from smoking can also pose a problem, said Jose Laya, who sells homes in Miami for between $800,000 and $2 million.

Not having natural light can make an apartment much less desirable, said Michael Bello of REAL New York, who handles $5,000-a-month rentals in New York City.

Lisa Camillieri of Warbug, who sells homes in Manhattan and Brooklyn in the $400,000 to $1.2 million range, said any property is sellable at the right price, but "a lack of light" is one factor that can "really turn buyers off."

"Nobody wants to live in a cave, so keep this in mind as you reno!" said Colin Turek of Compass in New York City, who sells in the $800,000 to $2 million range.

Delafraz of REAL New York said a death in a home can make it particularly difficult to sell.

"The factors that make [a home] unsellable are the ones that cannot be changed: location, low ceilings, difficult floor plan that cannot be easily modified, poor architecture," Robin Kencel of The Robin Kencel Group at Compass in Connecticut, who sells homes between $500,000 and $28 million, told Business Insider.

Other problems that can make a home unsellable include "significant environmental issues such as mold throughout the walls," Kencel said.

Some serious issues may not even be visible.

"What's under the hood? The foundation is cracked?" said Gill Chowdhury of Warburg Realty, who sells homes for an average of $2 million in Manhattan.

Neglecting major repairs and putting off necessary renovations can make a home unsellable, according to several realtors, including Rob McCann, an agent in Pennsylvania who sells homes for an average of $210,000, and Jason Tsalkas of Compass, who sells in the $650,000 to $2 million price range primarily in Brooklyn.

An outdated or badly decorated home can be basically impossible to sell, according to several realtors who spoke to Business Insider.

A home that's particularly "dated" can be unsellable, said Eric Mendelsohn, who sells homes for an average of $1 million in New York City.

Eric Goldie of Compass, who handles sales in New York City for $1 million to $5 million on average, cited "terrible decor and old kitchen and bathrooms" as potential deal-breakers.

Scot Dalbery from REAL New York, who deals with $4,000-a-month on average rental properties in New York City, said that although any home can sell for the right price, details like unattractive countertops in the kitchen can cause a home to sell for much less than its market average.

"Fine-tuning the small details in a home, even if having to invest in some updates, can really make a home's value increase," he said.

Sellers need to make sure their home is as attractive as possible in order to sell it, according to the realtors surveyed.

"It's important to do the necessary work to list the home such as any cosmetic work needed, decluttering, and staging," Jared Barnett of Compass, who sells homes from $2 million to $5 million in New York City, told Business Insider.

Maggie Ross of Compass, who sells homes in the $2 million range in Brooklyn, said sometimes it's the seller of the home itself that can keep it from selling.

"Unruly pets or an unwillingness to do the work to show the property — purging belongings, vacating the property for showings, removing pets from the home (especially loud or odorous pets), and a general attitude of not wanting to put your best foot forward," she said. "Those issues can prevent a sale."
