Hi Damion. Good for you. I have not noticed the same for mine. I actually heard a fellow agent who was talking about his insurance premium having gone up. Maybe your insurance is giving you a new discount that you are not aware of. Obviously, you may not want to call them ask why your premium went down.
My insurance actually stopped writing new home owners policies in CA altogether in July of this year (Allstate). They'll keep the insurance plans that are already in place and will renew them but will not write new policies. What's the name of your insurance?
