I cannot tell from your question whether you have a condo picked out already or not. If you are not sure and don't know what the Home Owners Association (HOA) fee covers, it is very important to know every condo association does NOT have the same coverage. I can only give you a couple suggestions for the interior if you are looking for insurance outside of the standard homewoners policy. I suggest you take your insurance agent a copy of the documents for the HOA and ask them to go look at the condo with you. They may have a formula for Sq Ft and age of structure to help you make an informed decision which is the key . It is very smart of you to research as you are doing so you can be an informed consumer.
