Hi Sit K
As I'm sure you know, its a little different in a condo so it depends what you're asking. The fire/homeowner's policy on the structure is part of your Homeowner's Association monthly assessment. In order to find out how much that will be, you'll need to look at how much of the monthly assessment applies to the insurance. All the owners have a percentage they pay toward costs based on the size of the complex, the size of your unit, and that's spelled out in the Homeowner Association by laws. If you need a copy of of the bylaws and someone in the transaction can't supply it to you, your Realtor or you can order this information for free from any title insurance company.
If you're talking about the paint in, including your personal belongings, that would be similar to a "renter's policy" and would be dependent on how much property you own and the type of coverage you want. You would obtain that policy on your own, and any homeowner's insurance agent would be happy to give you a quote. I would get 3 and compare, and you can probably do that online.
Hope that helps!
