The commission shall deny a petition if the commission determines that services cannot be extended to the petitioning premises at a reasonable cost. In making that determination, the commission shall consider all relevant factors, including:
(1) the original cost to be incurred by a designated provider to deploy service to the petitioning premises, and the effect of reimbursement of those costs on the state universal service fund;
(2) the number of access lines requested by the petitioners for the petitioning premises;
(3) the size of the geographic territory in which the petitioning premises are included;
(4) the proximity of existing facilities and the existence of a preferred designated provider under Section 56.213; and
(5) any technical barriers to the provision of service.
