The cost of the insurance for a house like that depends on a lot of things. The age of the house being one of the largest factors. Also, how big of a deductable you are wanting to have as well. Some of my clients take the 10% deductable do to the savings that it allows them and also, they are of the opinion that anything that happens do to wind would more than likely be just above their deductable amount that they would have to pay. Therefore they would rather pay way less for their Wind Insurance and pay for the damage. Still being covered in case of a catastrophic event.
Normally, I would say that a house that was built around 1980 would have insurances of no less than 4000 per year for all of the insurances and more than likely be at around 4500 to 5000. All using the lowest deductables available.
Another huge factor is the MIT form credits. This is a form that a home inspector would provide you that would give you very nice discounts off of your wind policy.
