You are so blessed... My flood insurance runs a little over $2,000 a year on the home I live in and my agent said that’s grandfathered in and to keep that policy. My other home insurance is higher than that... I’m so jealous of you...
Yikes, sorry to hear. The main loss risk here is from wind at certain times of year, mainly tree and roof damage. The people here say the town nickname is Paradise, it’s very unusual in many ways. Stumbled on it by accident. Best wishes for a solution or workaround for you!
