(a) If the board approves further consideration of an application, the board shall determine the proportionate amount of the bonded or contractual indebtedness for which the property to be excluded is liable as provided by this section.
(b) If the district has outstanding bonded indebtedness, the board shall obtain from the chief appraiser a certified copy of the appraised value of all the property to be excluded for the five years preceding the year in which the application is filed, as shown by the tax rolls of the district, and the appraised value of all taxable property in the district according to the most recent tax rolls of the district. The part of the district’s total outstanding bonded indebtedness to be paid by the applicant as a condition precedent to the exclusion of the property is that proportion of the indebtedness, including unpaid interest computed to the date of the order, that the appraised value of the property to be excluded bears to the appraised value of all taxable property in the district according to the most recent tax rolls.

(c) If the district has contractual or other indebtedness being repaid on the benefit tax basis, the board shall obtain from the appropriate records the manner in which the tax is assessed, and from those records the district shall calculate the part of the total outstanding indebtedness of the district remaining to be paid that is attributable to the property to be excluded.
(d) The order of the board approving further consideration of the application must also state the amounts required to be paid under § 49.3182 as a condition of the exclusion of the property.
