Lake Oswego firefighters arrived at a home at 1007 Lake Front Road Wednesday night to find flames shooting from the back of the house.
No one was injured in the blaze, as the house had recently sold in a deal set to close in about two weeks, according to the fire department.
Family members were still in the process of moving their belongings. Damage to the house was estimated at $70,000, with the home's contents valued at a loss of $10,000.
According to the fire department, crews from Lake Oswego Fire Engine 212 arrived within four minutes of a neighbor's 9-1-1 call at about 11:20 p.m. Wednesday. They quickly pulled hose lines out to protect a nearby home while extinguishing the flames.
'Flames were getting really close and the next-door house was of great concern,' said Lake Oswego Fire Lt. Troy Bany. It took about a half-hour to control the blaze.
Tualatin Valley Fire and Rescue assisted with Lake Oswego firefighters' efforts. As of Thursday, the cause of the fire remained under investigation.
