(1) The relatively expeditious and efficient administration and settlement of estates;
(2) The relative cost and convenience to the public and to the estates;
(3) Whether the fees provided under this article would be insufficient to fund the salary and expenses of a fiduciary supervisor as described in this article;

(5) The availability of physical facilities necessary for the administration of this article.
