It is likely that the amount to reconstruct your home will be different from the mortgage amount you take out. You certainly don’t want to miss the difference in case of a disaster such as a fire. For example, if you borrowed $250,000 after making a down payment of $50,000, that means the house is worth $300,000. But reconstructing it (including labor and materials) could cost up to $375,000. It is important to remember that there is a variation between buying and rebuilding your house.
