You have several sources to contact. First, if you have already entered escrow the Seller's will provide you with a Natural Hazard Disclosure Report (NHD). This independant, 3rd party report is typically paid for by the Seller's unless otherwise agreed to in writing. Your second source will be to contact your current Insurance provider and inform them that you're looking to purchase a home. By providing your current insurance provider with the address of the home they will be able to verify in their "CLUE" system any claims in the last 5 years for the home and inform you at that time if the home is insurable and what the cost will be. Make sure that you receive and read the NHD Report and contact your insurance provider during your due dilligence period. The Due Dilligence period is typically within 17 days after offer acceptence unless otherwise agreed to in writng. Your Realtor should be able to walk you through this process. Good luck!
