FISHER, J.
Damon Corporation (Damon) appeals the Elkhart County Board of Review’s (BOR) determination that Damon is liable for the additional taxes accessed against the property for 1989-1993.
Damon also appeals the State Board of Tax Commissioner’s (State Board) final determination denying Damon’s request to lower the assessed value of its property for the 1994 assessment year. In this original tax appeal, Damon presents the following issues for this Court’s review:
I. whether Damon is a bona fide purchaser as defined under Ind.Code Ann. § 6-l.l-9-4(b) (West 2000) and thus its property is not sub
ject to a lien for additional taxes assessed for the assessment dates prior to its purchase of the property;
II. whether the State Board’s determination that obsolescence should not be applied to Damon’s property in the 1994 assessment was arbitrary and capricious or an abuse of discretion; and
III. whether the State Board abused its discretion and acted arbitrarily and capriciously in failing to apply the kit building adjustment to Damon’s property in its 1994 assessment.
FACTS AND PROCEDURAL HISTORY
In 1989, Mallard Coach Company, Inc. (Mallard) owned two parcels of property with improvements in Elkhart County, Indiana.
Mallard appealed the 1989 property tax assessment on these two parcels to the State Board. While the appeal was pending, the property taxes were billed at the 1988 value. While the appeal was still pending, in December of 1992, Damon purchased the property from Mallard. On October 7, 1998, Damon was sent a bill for additional property taxes due 'for the tax years 1989-1992. This bill was a result of the State Board’s determination that the value of the property was higher than the 1988 assessment. In 1994, Damon filed a form 131 petition for review of assessment (131 Petition) with the State Board for the years 1989-1993 claiming that it was not liable for the taxes because it was a bona fide purchaser pursuant to I.C. § 6 — 1.1—9— 4(b). The State Board did not hold a hearing or make a final determination on Damon’s 131 Petition.
In addition, in 1994, Damon filed another form 131 petition for review of the 1994 assessed value of parcel number 40-13-35-202-11 with the Elkhart County Auditor’s Office. Thereafter, the State Board held a hearing on this 131 Petition. The State Board subsequently issued its final determination on Damon’s petition, lowering the assessed value of the improvements. However, the State Board declined to grant Damon any obsolescence depreciation or a kit building adjustment.
On January 6, 1997, Damon filed an original tax appeal with this Court appealing both the 1989-93 additional taxes for which it was billed and the State Board’s final determination regarding its 1994 assessment of parcel number 40-13-35-202-11. Additional facts will be provided as necessary.
ANALYSIS AND OPINION
Standard of Review
This Court gives final determinations of the State Board great deference when the State Board acts within the scope of its authority.
See Freudenberg-NOK General Partnership v. State Bd. of
Tax Comm’rs,
715 N.E.2d 1026, 1028-29 (Ind.Tax Ct.1999). Accordingly, this Court reverses final determinations of the State Board only when they are unsupported by substantial evidence, are arbitrary or capricious, constitute an abuse of discretion, or exceed statutory authority.
See id.
at 1029.
In addition, a taxpayer challenging the validity of the State Board’s final determination bears the burden of demonstrating the invalidity of the final determination.
See Clark v. State Bd. of Tax Comm’rs,
694 N.E.2d 1230, 1233 (Ind.Tax Ct.1998). The taxpayer must present a prima facie case (a case in which the evidence is “sufficient to establish a given fact and which if not contradicted will remain sufficient”).
GTE North Inc. v. State Bd. of Tax Comm’rs,
634 N.E.2d 882, 887 (Ind.Tax Ct.1994) (citations and internal quotation marks omitted). To establish a prima facie case, the taxpayer must offer probative evidence concerning the alleged error.
See King Indus, v. State Bd. of Tax Comm’rs,
699 N.E.2d 338, 343 (Ind.Tax Ct.1998);
Whitley Prods., Inc. v. State Bd. of Tax Comm’rs,
704 N.E.2d 1113, 1119 (Ind.Tax Ct.1998),
review denied.
“Once the taxpayer carries the burden of establishing a prima facie case, the burden shifts to the State Board to rebut the taxpayer’s evidence and justify its decision with substantial evidence.”
Clark,
694 N.E.2d at 1233. To carry its burden, the State Board must do more than merely assert that it assessed the property correctly.
Loveless Const. Co. v. State Bd. of Tax Comm’rs,
695 N.E.2d 1045, 1049 (Ind.Tax Ct.1998),
review denied.
Instead, the State Board must offer an authoritative explanation of its decision to rebut the taxpayer’s prima facie showing.

Discussion
I. Bona Fide Purchaser
The first issue is whether Damon is a bona fide purchaser as defined under I.C. § 6-l.l-9-4(b) and thus its property is not subject to a lien for additional taxes assessed for the assessment dates prior to its purchase of the property. As an initial matter, this Court notes that because the State Board did not make a final determination on this issue, this Court reviews this issue “in the same manner as if the state board had made a final determination affirming the county board of review’s action with respect to the assessment.” Ind. Code Ann. § 6-l.l-15-4(e) (West 1989);
See also supra
note 3. As this Court is statutorily instructed to review this issue as if it were a final determination, for purposes of clarity this Court hereafter will refer to it as a “final determination.”
Damon argues that pursuant to I.C. § 6-l.l-9-4(b) it is a bona fide purchaser of the parcels at issue and therefore its property is not subject to a lien for the additional taxes billed to it for the assessment dates prior to its purchase of the property.
Indiana Code § 6-1.1-9-4 provides:
(a) Real property may be assessed, or its assessed value increased, for a prior year
under this chapter
only if the notice required by section 1 of this chapter is given within three (3) years after the assessment date for that prior year.
(b) With'respect to real property which is owned by a bona fide purchaser without knowledge, no lien attaches for any property taxes which result from an assessment, or an increase in assessed value,
made under this chapter
for any period before his purchase of the property.
I.C. § 6-1.1-9^1 (emphasis added). This Court has previously stated that “[w]hen faced with a question of statutory interpretation, this Court looks first to the plain language of the statute. Where the language is unambiguous, this Court has no power to construe the statute for the purpose of
limiting or extending its operation.” Joyce Sportswear Co. v. State Bd. of Tax Comm’rs,
684 N.E.2d 1189, 1192 (Ind.Tax Ct.1997) (original emphasis) (in
ternal quotation marks omitted),
review denied.
The plain language of I.C. § 6-1.1-9-4 clearly mandates that both subsections (a) and (b) apply
only
to assessments or increased assessments made under Chapter 9, which governs the assessment of
omitted or undervalued
tangible property.
See id.
In
Joyce Sportswear Co. v. State Bd. of Tax Comm’rs,
this Court held that I.C. § 6-l.l~9^4(a) did not apply to proceedings under I.C. § 6-1.1-15-4.
See id.
Specifically, this Court held that by the language “under this chapter” in I.C. § 6-1.1-9^4(a) the General Assembly had limited the reach of the statute and that this Court did not have the power to extend the statute.
See id.
Similarly, this Court holds today that the reach of I.C. § 6-1.1-9-4(b) is limited to actions involving the assessment of omitted or undervalued tangible property under Chapter 9.
No evidence has been presented regarding Mallard’s reasons for appealing the 1989 assessment.
Consequently, there is no evidence that Mallard appealed the 1989 assessment on the basis that the property had been undervalued or omitted pursuant to I.C. § 6-1.1-9-1 to 9-9. As such, Damon is not afforded the protection of a bona fide purchaser under I.C. § 6-1.1 — 9—4(b) because the protection of that section is limited to assessments or reassessments under Chapter 9. Consequently, a prima facie case that Damon’s property should not be subject to a lien for the additional taxes has not been made.
See GTE North Inc.,
634 N.E.2d at 887. Therefore, this Court AFFIRMS the final determination, which held Damon’s property is subject to a lien for the additional taxes.
See Freudenberg-NOK,
715 N.E.2d at 1029.
II. Obsolescence
The next issue is whether the State Board’s determination that obsolescence should not be applied to Damon’s subject improvement in the 1994 assessment was arbitrary and capricious or an abuse of discretion. Damon contends that its property suffers from both functional and economic obsolescence. Specifically, Damon asserts that obsolescence “is warranted due to the proven poor market acceptability and low desirability of the property.” (Damon’s Post-trial Br. at 12.)
“The True Tax Value of a commercial improvement is determined by calculating the reproduction cost of the improvement (as determined by an application of the State Board regulations) and subtracting any physical and obsolescence depreciation.”
Loveless Const. Co.,
695 N.E.2d at 1047. The regulations define obsolescence as a functional and economic loss of value.
See
Ind.Ajdmin.Code tit. 50, r. 2.1-5-1 (1992) (codified in present form at
id.,
r. 2.2-10-7(e) (1996)). Functional obsolescence is caused by factors internal to the property and is “evidenced by conditions within the property.”
Id.
Economic obsolescence is caused by factors that are ex
ternal to the property.
See id.
In the commercial context, a loss of value usually represents a decrease in the improvement’s income generating ability.
See Loveless Const.,
695 N.E.2d at 1047. In
Clark v. State Board of Tax Commissioners,
this Court concluded that as a prerequisite for this Court to review a taxpayer’s case, during its hearing before the State Board the taxpayer must follow a two-step process whereby a taxpayer must first identify causes of obsolescence and then quantify the amount of obsolescence to be applied.
See Clark,
694 N.E.2d at 1241. However, as this case arose before
Clark,
the taxpayer here was not required to quantify its evidence, but simply to identify it.
See id.
This Court now looks to whether Damon’s contentions that its payment of less than the true tax value for the property, the vacancy of the property for over a year before Damon purchased it, or Damon’s building being under construction constitute a prima facie case that its property was entitled to 30% economic obsolescence for the 1994 tax year. Damon argues that its above stated contentions show that the property suffered from poor market acceptability and low desirability and therefore it is entitled to economic obsolescence. However, Damon does not cite any authority that supports low market acceptability and low desirability of the property as indicators of economic obsolescence, and the Court’s research reveals no authority for Damon’s proposition.
Cf. Pedcor Investments-1990-XIII, L.P. v. State Bd. of Tax Comm’rs,
715 N.E.2d 432, 436-37 (Ind.Tax Ct.1999) (holding that where the
-product
for which the property was constructed was rental apartments, economic obsolescence can be caused by deed restrictions because the marketplace may have a negative reaction to those restrictions). Therefore, Damon’s assertion is a mere allegation and does not constitute probative evidence that economic obsolescence is present.
See Whitley Prods., Inc.,
704 N.E.2d at 1119. Nonetheless, this Court addresses each of Damon’s contention’s below to determine if they show a loss in value that would indicate that obsolescence ^should be applied.
A. True Tax Value Verses Purchase Price
Damon argues that the disparity between the true tax value of its property and the price for which it purchased the property is evidence that the property has poor proven market acceptability and low desirability and is thus entitled to obsolescence. More specifically, Damon argues that it is entitled to economic obsolescence because the true tax value of the property is 33% greater than what it paid for the property. Damon presented evidence that the true tax value of the property was $296,670
and the price for which it purchased the property was $200,000. Damon seems to assert that the $200,000 price that it paid for the property was the property’s fair market value. (Damon’s Post-trial Br. at 13-14; Damon’s Reply Br. at 5
(arguing that the “purchase price was likely the result of an arms length transaction”); Trial Tr. at 14 (stating that “[Damon] came in and bought the property at a fair value”)). The difference between the true tax value of the property and price for which Damon purchased the property (market value) does not demonstrate a loss in value because the two numbers are not necessarily comparable.
See State Bd. of Tax Comm’rs v. Town of St. John,
702 N.E.2d 1034, 1038 (Ind.1998) (holding that “true tax value” is not exclusively or necessarily identical to fair market value). The statute in effect during the tax year for which Damon is appealing provides: “[w]ith respect to the assessment of real property,
true tax value does not mean fair market value.
True tax value
is the value determined under the rules of the state board of tax commissioners.” Ind. Code Ann. § 6-l.l-31-6(c) (West 2000) (emphasis added). Consequently, the difference between the true tax value of Damon’s property and the price Damon paid for the property, two unrelated numbers, does not demonstrate that there has been a loss in value of the subject improvement.
Thus, no probative evidence has been presented that identifies a cause of obsolescence here. Therefore, a prima fa-cie case has not been established that, based upon the difference between these numbers, obsolescence is present.
B. Vacancy of Building
Next, Damon argues that the vacancy of the building shows that the property has poor proven market acceptability and low desirability, thus making it eligible for obsolescence. At trial, Damon presented the testimony of an employee of a property tax consulting firm that the building was vacant for “well over a year” prior to Damon purchasing it. (Trial Tr. at 14.) However, a prima facie case has not been established because Damon has not presented any evidence explaining the reason that the property was vacant for over one year or whether the property was on the market during that time. Damon simply states that Mallard had filed for bankruptcy, without telling us the reasons for the bankruptcy. Accordingly, probative evidence has not been presented that identifies a cause of obsolescence here. Consequently, Damon’s unsupported allegation that the vacancy of the property prior to its purchase indicates obsolescence does not constitute a prima facie case that the property suffered a loss and is entitled to obsolescence.
See Herb v. State Bd. of Tax Comm’rs,
656 N.E.2d 890, 893 (Ind.Tax Ct.1995) (holding that “[a]llegations, unsupported by factual evidence, remain mere allegations”).
C. Building Under Construction
Finally, Damon argues that the lack of use of the building addition
while it was under construction warrants grqater than the forty percent obsolescence that it claims it was given previously in its assess
ment.
The State Board’s final determination concluded that Damon was entitled to zero obsolescence. Therefore, this Court looks to whether economic obsolescence can be applied to Damon’s addition while it was under construction.
Damon argues that obsolescence was applicable here because the building was only sixty percent complete and did not have heat or lights.
Therefore, Damon asserts that the building was “virtually useless” or “completely unusable.” (Damon’s Post-trial Br. at 14; Reply Br. at 5.)
In order for an obsolescence adjustment to be made, there must be some
loss
in value.
See Pedcor Investments,
715 N.E.2d at 439-40. Generally, obsolescence cannot be applied to a building that is under construction because its useful life has not yet begun.
See id.
at 440. This Court has previously stated that an “interpretation of the regulations to allow for an obsolescence adjustment merely because a building is vacant while it is under construction would lead to palpably absurd results.”
Id.
Damon is not entitled to economic obsolescence here because its building under construction had not begun its useful life.
See id.
Moreover, Damon’s assertion that its building was “virtually useless” or “completely unusable” while under construction does not demonstrate that it suffered a loss in value, because if it was being newly constructed, it would not have had any previous value to lose. (Damon’s Post-trial Br. at p. 14; Reply Br. at 5.) Therefore, no probative evidence has been presented that identifies a cause of obsolescence here. Consequently, a prima facie case of economic obsolescence has not been presented.
A prima facie case that Damon is entitled to functional
or economic obsolescence has not been presented.
See GTE North Inc.,
634 N.E.2d at 887. As such, the State Board is not required to rebut Damon’s case.
See Clark,
694 N.E.2d at 1233. Accordingly, this Court AFFIRMS the final determination of the State Board with regard to the obsolescence issues because Damon has not demonstrated that the State Board acted in an arbitrary and capricious manner.
See Freudenberg-NOK,
715 N.E.2d at 1029.
III. Kit Building
The final issue is whether the State Board abused its discretion and acted arbitrarily and capriciously in failing to apply
the kit building adjustment to Damon’s property in its 1994 assessment. The State Board bases its decision not to apply a kit building adjustment to Damon’s property on its assertion that Damon had altered the building structurally by adding two additions to the main building.
In 1991, the State Board amended its regulations to include a fifty percent reduction in the base rate for certain light pre-engineered or kit-type buildings.
See Whitley Prods.,
704 N.E.2d at 1121; Ind.Admin.Code tit. 50, r. 2.1-4-5 (Schedules A1 and A2) (1992) (codified in present form at
id.,
r. 2.2-11-6 (Schedule A.4) (1996)). Thereafter, the State Board issued Instructional Bulletin 91-8 to provide guidance to assessors in determining which light pre-engineered buildings qualified for the reduction.
See Componx, Inc. v. Indiana State Bd. of Tax Comm’rs,
683 N.E.2d 1372, 1374 (Ind.Tax Ct.1997). Generally, kit buildings are made of light weight and inexpensive materials and are “fabricated at central manufacturing facilities and shipped to the construction site ready for fast and efficient assembly.” Instructional Bulletin 91-8 at 1;
See also King Indus.,
699 N.E.2d at 339. The reduction in base price is offered because of the low cost and economical quality of materials used in kit buildings.
See King Indus.,
699 N.E.2d at 339.
Instructional Bulletin 91-8 sets forth several examples of common characteristics of low-cost kit buildings. According to Instructional Bulletin 91-8, the “key element in identifying this low cost economical ‘kit-type’ structure is the type of interior column and roof beam support.” Instructional Bulletin 91-8 at 4. Some examples of characteristics of these column and roof beam systems include: Cold Form Cee Channel wall supports, tapered columns, H columns, and steel post columns.
See id.
at 4-5. Instructional Bulletin 91-8 also provides assessors with “other identification clues” that a building is a “kit building” including: X bracing, metal or steel exterior skin, steel purlins and girders that are normally 14 to 16 gauge, concrete floors that have minimal tolerances, evenly spaced vertical supports, and normal building widths ranging from 30 feet to 120 feet.
Id.
at 6;
see also King Indus.,
699 N.E.2d at 339.
Damon argues that it is entitled to the kit building adjustment because it has presented evidence that its building qualifies for the adjustment. At trial, Mark Drew Miller testified on behalf of Damon, stating that “[t]he main structure, as far as the framing and the interior and exterior of the building, does comply with the guidelines set out by the State Tax Board.” (Trial Tr. at 17-18.) He also testified that the building had tapered columns, Cee channels, and cross bracing and that the building’s dimensions fell within the guidelines.
(Trial Tr. at 18) This is probative evidence that Damon’s building qualifies for the kit building adjustment.
See
Instructional Bulletin 91-8 at 4-6;
King Indus.,
699 N.E.2d at 339. Miller, however, noted that the attached office building would not qualify for the kit adjustment. Miller posited that the main 17,440 square foot structure qualified as a kit building. Because Damon has presented evidence that its building had tapered columns and Cee channels (both key factors in identifying kit buildings) as well as cross bracing, this Court concludes that Damon has established a prima facie case that its building is eligible for a kit building adjustment.
See King Indus.,
699 N.E.2d at 343;
Whitley Prods.,
704 N.E.2d at 1119.
Because Damon has presented a prima facie case, the burden shifts to the State Board to rebut Damon’s evidence and justify its decision with substantial evidence.
See King Indus.,
699 N.E.2d at 343;
Clark,
694 N.E.2d at 1233. The State Board did not contest Damon’s evidence. In fact, at trial, hearing officer Schultz, testified that “the main-the original structure less the three additions
that were added, excluding the original office, may have qualified for the kit adjustment.” (Trial Tr. at 28.) The State Board’s sole reason for denying the kit building adjustment was because the structure had been altered by two additions to the main building. (Def s Ex. A.)
It is true that changes that affect the structural integrity of a building
could
prevent it from receiving the kit building adjustment.
See Componx,
683 N.E.2d at 1375. However, under Instructional Bulletin 91-8, slight modifications or variations in the structural components of a pre-engineered building
do not necessarily
prevent it from qualifying for the kit adjustment.
See
Instructional Bulletin 91-8 at 7;
King Indus.,
699 N.E.2d at 342 n. 11;
Barker v. State Bd. of Tax Comm’rs,
712 N.E.2d 563, 570 (Ind.Tax Ct.1999) (stating that “Instructional Bulletin 91-8 allows kit buildings to have stronger structural support systems than that of the basic kit model”). Instructional Bulletin 91-8 allows improvements to deviate somewhat from the basic kit model and still qualify for the adjustment.
See Morris v. State Bd. of Tax Comm’rs,
712 N.E.2d 1120, 1123 (Ind.Tax Ct.1999);
Componx, Inc.,
683 N.E.2d at 1375; Instructional Bulletin 91-8 at 7. Instructional Bulletin 91-8 also discusses the use of grade factors in conjunction with the kit building adjustment. Instructional Bulletin 91-8 at 7. According to Instructional Bulletin 91-8, certain deviations from the basic kit model can be accounted for by increasing the grade of the improvement being assessed.
See Componx, Inc.,
683 N.E.2d at 1375; Instructional Bulletin 91-8 at 7;
King Indus.,
699 N.E.2d at 340. However, if the additional features of the kit building result in the building no longer being economical, then it cannot qualify for the kit adjustment. Instructional Bulletin 91-8 at 7. If a building does not qualify for the kit adjustment, an assessor may apply “a low grade and design factor to account for the lower cost of construction.”
King Indus.,
699 N.E.2d at 340-41 (internal quotations omitted).
During trial, the State Board presented testimony that a 39,000 square foot addition to the rear of the facility and a 4,000 square foot addition adjacent to the facility structurally modified the original structure. The State Board presents us with no authority for its proposition that additions to a building (that would otherwise qualify as a kit building) per se render the main structure ineligible. Beyond size, the State Board did not supply this Court with any description of the physical characteristics of the additions or any explanation of how the additions structurally modify the main building. Because the
additions identified by the State Board do not automatically disqualify the main building from receiving the kit adjustment, the State Board was required to do more than simply point to the additions to support its final determination in this case.
See Morris,
712 N.E.2d at 1124. Therefore, the State Board has not supported its decision to deny Damon the kit building adjustment with substantial evidence.
See Clark.,
694 N.E.2d at 1233. Consequently, the State Board’s final determination was arbitrary and capricious and an abuse of discretion.
Because Damon has presented a prima facie case that its building qualifies for the kit building adjustment and the State Board has not rebutted Damon’s case with substantial evidence, we REVERSE Damon’s case with regard to this issue and grant it the kit building adjustment.
See Morris,
712 N.E.2d at 1124. This Court REMANDS this issue to the State Board with the following instructions.
See id.
On remand, the State Board must assess the main building as a kit building and then adjust the assessment to account for the reproduction cost of the additional features.
See id.
at 1126. The State Board must quantify the effect of these additional features on the reproduction cost of the building and support its quantification with substantial evidence.
See id.
Moreover, because the application of the kit adjustment in this case may create an error in the D-2 grade assigned to the subject improvement, the State Board may alter the grade of the subject improvement.
See id.
However, any adjustment to the grade, other than to a C, must be supported with substantial evidence and the State Board is required to include detailed written findings explaining its calculations.
See id.;
Instructional Bulletin. 91-8 at 7 (providing that “[t]he basic version of the economy ‘kit type’ structure should be graded a ‘C’ ”). If the State Board adjusts the grade, Damon must be given the opportunity to present evidence relevant to the grading of the subject improvement.
See Barker,
712 N.E.2d at 571. In making its assessment, the State Board may assess the main building separately from its additions
when determining the assessed value of that improvement, just as an assessor may assess any improvement by breaking the improvement into parts and assessing those parts separately.
See Morris,
712 N.E.2d at 1126. Instructional Bulletin 91-8 does not mandate that improvements alleged to qualify for the kit adjustment must necessarily be assessed as a whole.
See id.
CONCLUSION
For the foregoing reasons, the Court hereby AFFIRMS the Elkhart County Board’s determination that Damon is liable for the additional taxes assessed for the years prior to Damon’s purchase of the property. This Court hereby AFFIRMS the State Board’s determination that Damon is not entitled to an obsolescence adjustment for its 1994 property assessment. This Court hereby REVERSES the State Board’s final determination as it relates to the applicability of the kit building adjustment to Damon’s 1994 property assessment and REMANDS this issue to the State Board for further proceedings consistent with this opinion.
