Our insurance on our new house is actually less than our old house which I found strange (and it's lower with a different insurane company that we are switching to). Our old house was a limestone structure which is very expensive to replace (I'm told). DH grandfather built it and used the best materials and it replace it, it was pretty expensive. Our new house is brick and is much cheaper to insure even with the increased square feet. But we are doing comparison shopping and a new insurance company offers better coverage for a lower premium so we are considering switching.
I personally take issue with the replacement value, especially when it comes to personal belongings. The formula is 70-75% of the house(structure) replacement cost.
We pay $4130 in annual property taxes which I expect to increase in 2009. It's expensive and about $500 more per year than our old house. But property taxes support schools which employ my husband and educate my children so it's a catch-22 in our house. Complain about property taxes but need the job, LOL.
