How do I calculate the dwelling coverage I need from the information I have?
You can't compare the different quotes unless they have the same numbers to work with. The big companies should use similar models to come up with values for the contents. In many cases they will assume some standard values for things like appliances. Yes you have a stove, but unless it is commercial grade they won't care when giving you a quote. If you have very expensive items you may need a rider to cover them. There is not relationship between the county assessment and the cost to rebuild. The insurance doesn't cover the land. You have to make sure that all quotes include the same riders: cost to put you in a motel, flood insurance... and the same deductibles. Your state may have an insurance office that can help answer your question.  Here is the one for Virginia.
