Christopher Bishop, 50, who lived alone, was found dead inside the two-story home at 4203 Lake Rill Court in Marietta.
The Cobb County Fire Department, which received a 911 call at 2:31 a.m. Sunday, was on the scene seven minutes later to find heavy fire on the second floor and in the attic, with the blaze spreading to the first floor.
Police said there were no signs of foul play or suspicious activity at the scene.
Eric Cooney, president of the homeowner’s association representing the 97-home subdivision, said an investor bought the house about a year ago and rented it to Bishop.
The cause of the fire remains under investigation, said Cobb Fire Department Lt. Dan Dupree.
