The real estate agency blamed Brexit, the increase in VAT rates and poor publicity for failing to sell a unique island hotel off the coast of Donegal.
A number of outsiders have expressed strong interest in buying a 14-bedroom Thstan Thóraigh or Tory Island hotel, which was priced at € 400,000.
These included a hotelier from Belgium, a retired couple from Dublin and a US-based priest who wanted to turn the hotel into a retreat center.
The bidding deadline was August 31st.
However, the real estate agent Gareth McLaren of Glenn Estates has revealed that the hotel has not yet been sold.
He said that despite the current owners trading successfully and the hotel being occupied, a number of factors have hindered the sale.
"We have not yet received a satisfactory offer for the hotel and therefore it will remain on the market.
"In my opinion, there are a number of factors that impede sales.
"All those interested in buying the hotel were outside Donegal and the common area and would be dependent on a number of factors.
"I think uncertainty about Brexit should be a major factor. Also, raising the VAT rates for hotels and hotels from 9% to 13.5% certainly did not help.
The hotel is still owned by former headlamp Sean Doherty and his family.
Mr McLaren said Zona's daughter and son-in-law now run the business and enjoy a good season and continue to trade well.
"This is a unique endeavor and will not suit everyone, but the hotel is still successfully traded by the Doherty family and is doing well.
"The hotel will remain for sale and we hope someone will buy it and continue to manage it successfully," he said.
The 14-bedroom hotel has a bar and restaurant.
The family-run and run hotel is the largest employer on the island and is the center of many of the island's historic moments since the 19th century.
The business dates back to the late 1800s, when the Ward family operated a hotel and a general store, delivering everything from salted fish to a candle light.
The store traded passing ships, while people from what the Tory Islanders called "the country" also made regular shopping trips to the Words from the mainland.
Once Roger Cage stayed at the hotel, and the signer of the Easter Proclamation, Joseph Mary Plunkett, sent a postcard from the hotel on his second visit to the island in 1914. He wrote, however, that he had not stayed at the hotel since Mr Ward was "very sombre ".
With a total population of about 140 islanders (double that of summer), the island, which has sunk in the Atlantic, is steeped in history, mythology and folklore.
The island outpost has long been a favorite getaway for artists, nature lovers, bird watchers and many who just want to be off for a few days.
Tory Island is part of Donegal's Genel and has one of the highest percentages of native Irish speakers anywhere in Ireland.
The only access to the island is by ferry and each crossing takes about an hour. The ferry operates four times a day during the summer season and twice a day during the winter months.
