A fire broke out Sunday morning at 3:30 a.m. at 1819 Hollipark Drive in Idaho Falls.
Units with the Idaho Falls Fire Department were dispatched to a double-wide trailer home after the neighbor woke to the smell of smoke.
The fire had already burned through the floor and was coming from the left side dining room windows and below the structure when the fire department arrived.
The trailer was vacant and had just been listed for sale last night.
The estimated damage is $35,000.
The fire is still under investigation.
