Unless otherwise provided by local statute, the executor of a will'and the administrator of an intestate estate, have no power over the real estate of the decedent. There is an exception, however, which provides for failure of the personal estate to satisfy the debts left by the decedent. In such a case resort may be had to the real estate. Such real estate may be sold as will be necessary to pay the debts of the decedent. The statutes of the different states usually dictate the mode of procedure when this condition of affairs arises.7
