The man, who was named locally as Neil ‘Biddy Rua’ McClafferty, was found by a passer-by at around 1.40am.
Units of both Falcarragh and Milford Fire Stations rushed to the scene but the later Mr McCalfferty was found dead at the scene.
Garda forensics officers were at the scene of the blaze this morning as smoke continued to billow from the hilltop residence.
Mr McClafferty was a well-known and highly-respected figure in the local community.
Although he lived alone, he was well-looked after by his family who lived in the locality.
A Garda spokesman said an investigation into the incident is continuing.
“Officers are at the scene and a full investigation is being carried out into the cause of the blaze.
“Our deepest sympathy goes to the dead man’s family,” he said.
