Never underestimate the process and length of time it may take to get insurance coverage, especially if you’re buying a detached house.
In my experience, the insurance agent is most interested in anything that has to do with water: the condition of the roof, the water tanks, the pipes, the plumbing, the water sprinkler system, and any heating system that depends on water. The condition of the wood-burning fireplace and everything connected to it is the second biggest concern for the insurance agent.
