Your basis in the house is its value at the date of your late husband's death. Gain will be measured against that amount. If you file a joint return with your new husband, you can exclude up to $500,000 of gain. (If you file separate, only $250K.) If you buy another house in Los Angeles County and are old enough, you may be able to keep your low property taxes and transfer that level to the new house.
