A Garages House.
There are a bunch of house surround this kind of garages and it's suprisingly good for a solo player as well. The 2 storey house provide a good loot and also atleast 1 assault rifle with good amount of bullet to secure a kill, also a yellow house behind garages can also sometime provide a good loot as well.
