Insurance Buyer’s Guides. Visit the website for the National Association of Insurance Commissioners, where you will find a map at www.naic.org/state_web_ map.htm through which you can link to your state insurance regulator’s website. If available in your state, obtain an insurance buyer’s guide for automobile and homeowner’s insurance that describes policy provisions and compares insurance rates. Use these rate comparisons to select two automobile insurance companies that would be appropriate for your needs. E-mail or telephone the companies to obtain specific premium quotations for the desired insurance protection. Do the same for single-family dwelling, condominium, or renter’s insurance, depending on your circumstances.
