Per Curiam.
{¶ 1} In this real-property-valuation case, the Board of Tax Appeals (BTA) relied on an appraisal report furnished by appellees Washington County Board of Revision (the BOR) and Washington County auditor (collectively, the county) to value a property owned by appellants, Lowes Home Centers, Inc. and Lowes Home Centers, L.L.C. (collectively, Lowes). Although Lowes presented its own appraisal report, the BTA found that the countys report constituted the most competent and probative evidence of the value of the subject property for tax year 2013. Lowes has appealed.
{¶ 2} We conclude that our decisions in Steak N Shake, Inc. v. Warren Cty. Bd. of Revision , 145 Ohio St.3d 244, 2015-Ohio-4836, 48 N.E.3d 535, Rite Aid of Ohio, Inc. v. Washington Cty. Bd. of Revision , 146 Ohio St.3d 173, 2016-Ohio-371, 54 N.E.3d 1177, and Lowes Home Centers, Inc. v. Washington Cty. Bd. of Revision , 145 Ohio St.3d 375, 2016-Ohio-372, 49 N.E.3d 1266, provide the proper guideposts for resolving this controversy. The BTA, however, did not take this trilogy into account, and understandably so; at the time of the BTAs decision, Steak N Shake had just been decided and Rite Aid and Lowes had not yet been decided. Because the BTA, as the finder of fact, has yet to evaluate the evidence in this case in light of the legal standards articulated in those decisions, we vacate its decision and remand the cause for further proceedings.
FACTS AND PROCEDURAL BACKGROUND
{¶ 3} The property at issue consists of five parcels constituting roughly 16 acres of land in Marietta. The property is improved with a 142,446-square-foot home-improvement store. The store is owned and occupied by Lowes and was constructed in 2002. For tax year 2013, the county auditor valued the property at $9,595,570; Lowes challenged that valuation with a decrease complaint.
BOR proceedings
{¶ 4} At the BOR hearing, Lowes presented an appraisal report and supporting testimony from Richard G. Racek Jr., a certified appraiser. Raceks report describes the appraisal as valuing the fee-simple interest in the property. He opined that the propertys highest and best use, as improved, is its continued retail use and, as vacant, is a permitted retail use.
{¶ 5} Racek performed a sales-comparison and an income approach to value. For the sales-comparison approach, Racek evaluated nine transactions involving big-box stores located throughout Ohio. Six involved unoccupied properties that sold in the absence of a lease. The remaining three involved properties that sold with a lease in place. When appropriate, Racek made adjustments to the properties to account for such characteristics as location, condition, land-to-building ratio, and rental rate.
{¶ 6} For the income approach, Racek evaluated 20 properties. Eleven of these involved properties with a lease in place, five involved properties with an asking rental rate, and the remaining four involved Lowes stores that were leased as of the January 1, 2013 tax-lien date. Racek noted adjustments to the rent comparables when appropriate.
{¶ 7} After reconciling the two approaches, Racek opined a value of $5,700,000 as of January 1, 2013.
{¶ 8} The BOR retained the county auditors valuation of $9,595,570, in accord with the recommendation of its technical adviser.
BTA proceedings
{¶ 9} At the BTA hearing, the county presented an appraisal report and supporting testimony from Thomas D. Sprout, a certified appraiser. According to Sprout, he appraised the propertys unencumbered, fee-simple interest. He opined that the propertys highest and best use as improved is its existing use and as vacant is a retail building consistent with the localitys zoning provisions.
{¶ 10} Sprout performed a sales-comparison and an income approach to value. For the sales-comparison approach, Sprout attempted to find big box users, retail users, that were occupying their building at the point of sale. He evaluated seven transactions. Five involved properties where the sale occurred with a lease in place. He described the sixth transaction as the sale of a Costco Wholesale store without a lease in place. But on cross-examination, counsel for Lowes presented to Sprout evidence that the sixth transaction was instead a buyout of a ground lease, to which Sprout responded that had he known that the sale was a buyout of a ground lease, he would not have included it in his report. The seventh transaction involved a sale without a lease in place, but Sprout stated that he gave this sale no weight. When appropriate, Sprout noted adjustments to the comparables for property rights conveyed, market conditions, location, and building size and condition.
{¶ 11} For the income approach, Sprout evaluated eight properties. He strove to identify occupied units where leases were recently renewed and instances when second time users [were] coming into the property. Sprout noted whether the location and condition of each rent comparable was superior, inferior, or similar to those of the subject property. He then noted whether the rent for each comparable fell on the lower, middle, or upper end of the range as compared to what the subject property could rent for if it was not owner-occupied.
{¶ 12} In his final reconciliation, Sprout gave equal weight to the sales-comparison and income approaches, opining a value of $8,800,000 as of January 1, 2013.
{¶ 13} The BTA concluded that Sprouts appraisal provided the most competent and probative evidence of the subject propertys value. The BTA found that in contrast to Raceks heavy reliance on second-generation sales, Sprouts inclusion of first-generation properties and build-to-suit properties subject to long-term leases was most appropriate, given that [Lowes] occupied the subject property as of the tax lien date. BTA No. 2014-4606, 2015 WL 11018613, *3 (Dec. 3, 2015). It found persuasive Sprouts characterization of the property as being situated in a regional hub. Id. at *4. And it found that Sprouts selection of comparable properties and his adjustments to those properties were proper. The BTA also rejected Lowes argument that Sprouts appraisal-especially his reliance on comparable sales of lease-encumbered properties-violated R.C. 5713.03 as amended by 2012 Am.Sub.H.B. No. 487 (H.B. 487), which directs county auditors to value property in its fee-simple estate, as if unencumbered.
{¶ 14} After the BTA issued its decision, Lowes filed a motion urging the BTA to reconsider its decision in light of Steak N Shake , 145 Ohio St.3d 244, 2015-Ohio-4836, 48 N.E.3d 535, which we decided about a week before the BTA issued its decision. But given the looming deadline to appeal, Lowes filed its notice of appeal to this court instead of waiting for the BTA to rule on the motion.

DISCUSSION
First proposition of law
{¶ 16} In its first proposition of law, Lowes argues that the BTA erred in finding that Sprouts appraisal provided the most competent and probative evidence of value. According to Lowes, the BTA should have disregarded Sprouts appraisal because he placed significant reliance on sales of comparable properties with leases in place (what Lowes calls leased fee sales) in contravention of R.C. 5713.03 and this courts case law.
{¶ 17} Under the H.B. 487 version of R.C. 5713.03 (which is the version of the statute applicable in this case), county auditors were required to determine the true value of the fee simple estate, as if unencumbered of each separate tract, lot, or parcel of real property and of buildings, structures, and improvements located thereon. (Emphasis added to indicate words inserted by H.B. 487.) See also Terraza 8, L.L.C. v. Franklin Cty. Bd. of Revision , 150 Ohio St.3d 527, 2017-Ohio-4415, 83 N.E.3d 916, ¶ 18 (the H.B. 487 version of R.C. 5713.03 applies to real-estate valuations for tax year 2013). In Terraza , we explained that H.B. 487s amendment to R.C. 5713.03means that the BTA ha[s] to determine the value of the subject propertys unencumbered fee-simple estate. Id. at ¶ 39.
{¶ 18} Lowes and the county differ on what this amendment encompasses. Lowes asserts that a lease constitutes an encumbrance, whereas the county asserts that liens and easements constitute encumbrances but that leases do not. Lowes is correct, as is clear from a number of our real-property-valuation decisions. See Terraza at ¶ 1 (lease-encumbered properties); Rite Aid , 146 Ohio St.3d 173, 2016-Ohio-371, 54 N.E.3d 1177, at ¶ 19 (property encumbered by a lease); Lowes , 145 Ohio St.3d 375, 2016-Ohio-372, 49 N.E.3d 1266, at ¶ 25 (unencumbered by a lease); Steak N Shake , 145 Ohio St.3d 244, 2015-Ohio-4836, 48 N.E.3d 535, at ¶ 33 (same).
{¶ 19} In view of these decisions, it is plain that a lease is an encumbrance and that R.C. 5713.03s directive to value the realty as if unencumbered means to value the realty as if it were free of encumbrances such as leases. It follows that a valuation of a lease-encumbered property that has not been adjusted for the presence of the lease runs afoul of R.C. 5713.03. According to Lowes, the BTA violated R.C. 5713.03 by relying on Sprouts appraisal, which in Lowes view constitutes a leased fee valuation because Sprout relied on comparable sales of lease-encumbered properties. But Lowes argument runs into two difficulties.
{¶ 20} First, Sprout himself said that he conducted a market-value appraisal of the subject property as an unencumbered, fee-simple estate. The fact that he appraised the property as such is not unexpected, because it is, in fact, unencumbered by a lease. Second, the language of R.C. 5713.03 applies to the valuation of the property itself-it does not prescribe any standards to be applied in a comparable-sales analysis. Lowes statutory argument, in effect, would have us insert words that the General Assembly did not use. We decline to do so. See Wheeling Steel Corp. v. Porterfield , 24 Ohio St.2d 24, 28-29, 263 N.E.2d 249 (1970) (Neither the Board of Tax Appeals, nor this court, may legislate to add a requirement to a statute enacted by the General Assembly).
{¶ 21} Notwithstanding Sprouts ostensible compliance with R.C. 5713.03, Lowes argues that a more searching inquiry into Sprouts appraisal shows that in substance he valued the property as if it were encumbered by a lease and that he relied on comparable sales of lease-encumbered properties only to inflate the subject propertys value. In translating this assertion to a claim of legal error, Lowes places principal reliance on a trilogy of decisions of this court: Steak N Shake , 145 Ohio St.3d 244, 2015-Ohio-4836, 48 N.E.3d 535 ; Rite Aid , 146 Ohio St.3d 173, 2016-Ohio-371, 54 N.E.3d 1177 ; and Lowes , 145 Ohio St.3d 375, 2016-Ohio-372, 49 N.E.3d 1266.
{¶ 22} In Steak N Shake , we ruled that [b]ecause the encumbrance of a lease may affect market value, sale prices of leased properties generally must be adjusted when determining the value of comparable unleased properties. Id. at ¶ 34-35 (intervening subheading). There, a countys appraiser valued an owner-occupied property based in part on a sales-comparison approach that relied solely on unadjusted comparable sales of lease-encumbered properties. Id. at ¶ 13-14.
After the BTA adopted the appraisers valuation, the owner appealed and faulted the appraiser for fail[ing] to adjust the sales prices of the comparable properties to remove the effect that long-term leases would have had on those prices. Id. at ¶ 33. One of amicus curiaes arguments in response was that the approach of the countys appraiser was justified under this courts pre-H.B. 487 line of decisions, e.g., HIN, L.L.C. v. Cuyahoga Cty. Bd. of Revision , 138 Ohio St.3d 223, 2014-Ohio-523, 5 N.E.3d 637, ¶ 19-20 (collecting cases), which stood for the proposition that the price from a recent arms-length sale need not be adjusted to account for the presence of a lease.
{¶ 23} We agreed with the owner, finding that the BTA erred by accepting the value opined by the countys appraiser: Precisely because the encumbrances affect sale price, and precisely because the difference in sales price is a difference in value for tax purposes, [the countys appraiser] was required to adjust the sale prices for his comparable properties to reflect the fact that the subject property was not encumbered and would therefore likely sell for less. (Emphasis sic.) Id. at ¶ 36.
{¶ 24} A similar dispute arose in Rite Aid , 146 Ohio St.3d 173, 2016-Ohio-371, 54 N.E.3d 1177, in which it was argued that comparable sales of lease-encumbered properties do not need to be adjusted in determining the value of an unencumbered property. Relying on Steak N Shake , we rejected that argument and reaffirmed the general rule, Rite Aid at ¶ 22, that when a lease affects the sale price and value, the leased-fee comparable ought to be adjusted when the subject property has no lease; the adjustment would remove the effect of the lease on the sale price so that the sale can indicate what the unencumbered property would sell for, id. at ¶ 20.
{¶ 25} Last in the trilogy is Lowes , 145 Ohio St.3d 375, 2016-Ohio-372, 49 N.E.3d 1266, which involved the same property at issue here. In that case, we reiterated the principles of Steak N Shake but remanded the case to the BTA to determine whether the special-purpose doctrine applied. Id. at ¶ 18. We observed that [i]f the special-purpose doctrine does not apply, the value of any comparables that were subject to leases should be adjusted to achieve a true comparable for this subject property * * * [but] if the special-purpose doctrine does apply, it may be appropriate to use such comparables without adjustment. Id. at ¶ 25. On remand, the BTA determined that the property did not qualify as a special-purpose property.
Lowes Home Centers, Inc. v. Washington Cty. Bd. of Revi sion , BTA No. 2011-1664, 2016 Ohio Tax LEXIS 1270, *12-13 (June 10, 2016) (Lowes Remand ).
{¶ 26} In this case, Sprout performed the sales-comparison approach by evaluating seven transactions, five of which indisputably involved lease-encumbered properties. According to the county, Sprout made appropriate adjustments to these five sales in conformity with Steak N Shake , Rite Aid , and Lowes . Specifically, the county cites Sprouts statement that he made appropriate adjustments for property rights conveyed. During oral argument, the county commented on Sprouts approach, explaining that he essentially performed a two-step analysis: first, he determined whether the rent for each particular comparable property was above, below, or at market at the time of sale; second, he evaluated how the rent for each particular property compared to what the subject property could generate.
{¶ 27} As to the first step, Sprout stated that the rent for each of the five comparable properties was at market at the time of the sale. As to the second step, Sprout noted that the rent for the first property was lower than what we believe the subject property could achieve and would represent a lower value, necessitating an upward adjustment. For the second, third, and fourth properties, Sprout noted that the rents were higher than what we believe the subject property could achieve and would represent higher values, necessitating a downward adjustment. And for the fifth property, Sprout stated that an upward adjustment was required because there was a recently negotiated lease.
{¶ 28} It is possible that a finder of fact might regard Sprouts property-rights-conveyed analysis as competent and probative evidence of value, thereby permitting the conclusion that Sprouts adjustments are in keeping with Steak N Shake , Rite Aid , and Lowes . But the difficulty here is that the BTA did not make any express findings about Sprouts property-rights-conveyed analysis. True, the BTA found that Sprouts selection of comparable properties and the adjustments he made thereto, as highlighted in his appraisal report, were appropriate. 2015 WL 11018613 at *4. Thus, one might infer that the BTA indirectly evaluated Sprouts property-rights-conveyed analysis. But that inference is vulnerable to challenge because the BTAs decision does not mention Steak N Shake , Rite Aid , or Lowes . Any consideration that the BTA may have given to Sprouts adjustments was therefore not done with an eye toward whether his property-rights-conveyed analysis conformed to that trilogy of decisions.
{¶ 29} Indeed, it is questionable whether the BTA regarded the adjustments as necessary at all given its citation to Cummins Property Servs., L.L.C. v. Franklin Cty. Bd. of Revision , 117 Ohio St.3d 516, 2008-Ohio-1473, 885 N.E.2d 222, and AEI Net Lease Income & Growth Fund v. Erie Cty. Bd. of Revision , 119 Ohio St.3d 563, 2008-Ohio-5203, 895 N.E.2d 830. Based on those pre-H.B. 487 decisions, in which we held that a propertys sale price does not require an adjustment to account for the presence of an encumbrance in determining that propertys true value, the BTAs decision could be read as endorsing the notion that the sales of lease-encumbered properties considered in a sales-comparison approach likewise do not require adjustments to account for encumbrances.
{¶ 30} At bottom, the BTAs key job in a battle-of-the-appraisals dispute is to weigh evidence and assess the credibility of the appraisals. See EOP-BP Tower, L.L.C. v. Cuyahoga Cty. Bd. of Revision , 106 Ohio St.3d 1, 2005-Ohio-3096, 829 N.E.2d 686, ¶ 9. [T]he BTA must engage in sufficient discussion of the evidence to permit the court on appeal to determine whether the BTA acted reasonably and lawfully. Lutheran Social Servs. of Cent. Ohio Village Hous., Inc. v. Franklin Cty. Bd. of Revision , 150 Ohio St.3d 125, 2017-Ohio-900, 79 N.E.3d 541, ¶ 12. Because the BTA has yet to evaluate and weigh the property-rights-conveyed analysis contained in Sprouts appraisal report under the appropriate legal standards, we vacate the BTAs decision and remand the case so that the BTA can carry out this duty.
Second proposition of law
{¶ 31} In its second proposition of law, Lowes argues that its property does not meet the requirements of the special-purpose doctrine. It further maintains that treating the property as special purpose in nature would violate its equal-protection rights under both the Ohio and United States Constitutions. The BTAs decision contains no discussion of the special-purpose doctrine. It thus appears that Lowes has asserted this argument as a protective measure to foreclose the BTA from making such a special-purpose finding in the event of a remand. For the reasons that follow, we need not reach the merits of this proposition of law.
{¶ 32} After the county filed its merit brief-but before Lowes filed its reply brief-the BTA issued its decision on remand in Lowes , finding that the subject property did not qualify for special-purpose treatment. Lowes Remand , 2016 Ohio Tax LEXIS 1270, at *13 (we are constrained to conclude that it has not been demonstrated by either appraiser that the subject property constitutes a special purpose property). Relying on this finding of the BTA, Lowes has asserted in its reply brief that the doctrine of res judicata requires this court to conclude that the special-purpose doctrine does not apply to the property.
{¶ 33} Collateral estoppel is an aspect of res judicata, see Grava v. Parkman Twp. , 73 Ohio St.3d 379, 381, 653 N.E.2d 226 (1995), and it precludes the relitigation, in a second action, of an issue that has been actually and necessarily litigated and determined in a prior action, Warrensville Hts. City School Dist. Bd. of Edn. v. Cuyahoga Cty. Bd. of Revision , 152 Ohio St.3d 277, 2017-Ohio-8845, 95 N.E.3d 359, ¶ 9, quoting Whitehead v. Gen. Tel. Co. , 20 Ohio St.2d 108, 112, 254 N.E.2d 10 (1969). [C]ollateral estoppel may under appropriate circumstances be applied to decisions of the BTA. New Winchester Gardens, Ltd. v. Franklin Cty. Bd. of Revision , 80 Ohio St.3d 36, 41, 684 N.E.2d 312 (1997), overruled on other grounds , Cummins , 117 Ohio St.3d 516, 2008-Ohio-1473, 885 N.E.2d 222, at ¶ 23. In the real-property-valuation context, we have held that the determination in an earlier year of a discrete factual/legal issue that is common to successive tax years may bar relitigation of that discrete issue in the later years. Olmsted Falls Bd. of Edn. v. Cuyahoga Cty. Bd. of Revision , 122 Ohio St.3d 134, 2009-Ohio-2461, 909 N.E.2d 597, ¶ 17. Thus, for instance, we have held that collateral estoppel may be applied to bar the relitigation of a sales arms-length nature. See New Winchester Gardens at 42, 684 N.E.2d 312.
{¶ 34} Applying these principles, we conclude that collateral estoppel precludes us from inquiring into whether the subject property is special purpose in nature. First, the BTAs decision on remand shows that the issue was actually litigated in the prior proceeding. Second, as each partys counsel stated at oral argument, the property at issue in the prior proceeding is the same property at issue here. And finally, Lowes Home Centers, Inc., and the county were parties to the prior proceeding and are parties to this proceeding.
{¶ 35} One last bit of analysis remains, however, because Lowes Home Centers, L.L.C., which appears on the complaint alongside Lowes Home Centers, Inc., as a property owner and is listed on the BORs and BTAs decisions of value, does not appear to have participated as a party in the prior proceeding. We have stated that collateral estoppel operates only when there is an identity of issues and an identity of parties or their privies in both the first and the second suit. Progressive Plastics, Inc. v. Testa , 133 Ohio St.3d 490, 2012-Ohio-4759, 979 N.E.2d 280, ¶ 17, quoting Whitehead , 20 Ohio St.2d at 113, 254 N.E.2d 10. The presence of Lowes Home Centers, L.L.C., as a party here means that the parties to this proceeding are not entirely identical to the parties to the prior proceeding. But we conclude that there is no bar to applying collateral estoppel under these circumstances.
{¶ 36} We have recognized that a party precluded [by collateral estoppel] from relitigating an issue with an opposing party likewise is precluded from doing so with another person unless he lacked [a] full and fair opportunity to litigate that issue in the first action, or unless other circumstances justify according him an opportunity to relitigate that issue.
Hicks v. De La Cruz , 52 Ohio St.2d 71, 74, 369 N.E.2d 776 (1977). The nonmutual application of collateral estoppel in a case like Hicks furnishes authority for allowing the doctrine to operate here. As evidenced by the existence of adversarial briefing during the remand proceedings, see Lowes Remand , 2016 Ohio Tax LEXIS 1270, at *2, we conclude that the county had a full and fair opportunity to litigate the special-purpose issue on remand, and we are aware of no other circumstances that would justify allowing the county an opportunity to relitigate that issue here.
The BTA did not adopt a present-use valuation
{¶ 37} Lastly, we address Lowes assertion that the BTA performed an unconstitutional present-use valuation in adopting Sprouts appraisal. Present-use valuation violates Article XII, Section 2 [of the Ohio Constitution] because that method of evaluation excludes, among other factors, location and speculative value which comprise market value. Johnston Coca-Cola Bottling Co., Inc. v. Hamilton Cty. Bd. of Revision , 149 Ohio St.3d 155, 2017-Ohio-870, 73 N.E.3d 503, ¶ 13, quoting State ex rel. Park Invest. Co. v. Bd. of Tax Appeals , 32 Ohio St.2d 28, 33, 289 N.E.2d 579 (1972). But while present use cannot ordinarily be the criterion of value, the BTA can consider it as a noncontrolling factor. Johnston Coca-Cola Bottling Co. at ¶ 14. Here, the BTA devoted an entire paragraph of its analysis to discussing the propertys location, agreeing with Sprout that the property was situated in a regional hub. 2015 WL 11018613 at *4. The BTAs discussion of the property from a locational standpoint defeats Lowes argument that Sprout considered the propertys present use as the only criterion of value.
CONCLUSION
{¶ 38} For the foregoing reasons, we vacate the BTAs decision and remand the cause to the BTA for evaluation and weighing of the property-rights-conveyed analysis contained in Sprouts appraisal report under the appropriate legal standards.
Decision vacated and cause remanded.
OConnor, C.J., and ODonnell, French, and Fischer, JJ., concur.

A ground lease is a lease that grants the right to use and occupy land. N. Royalton City School Dist. Bd. of Edn. v. Cuyahoga Cty. Bd. of Revision , 129 Ohio St.3d 172, 2011-Ohio-3092, 950 N.E.2d 955, ¶ 1, fn. 1, quoting American Institute of Real Estate Appraisers, The Dictionary of Real Estate Appraisal 146 (1984).
A second-generation space is a building or space used by a tenant other than the original tenant, Appraisal Institute, The Dictionary of Real Estate Appraisal 210 (6th Ed.2015), whereas a first-generation space is a building or space designed to be functionally and economically efficient for the original tenant or a similar class of tenants over a period of time, during which the space retains its original utility and desirability, id. at 92.
While this appeal was pending, the BTA purported to grant reconsideration and to vacate its original decision pending further proceedings before the BTA. No party, however, argues that we should give effect to the BTAs grant of reconsideration. Indeed, the BTA lost jurisdiction over the case when Lowes filed its notice of appeal, meaning that the BTAs grant of reconsideration was a nullity. See Johnston Coca-Cola Bottling Co., Inc. v. Hamilton Cty. Bd. of Revision , 149 Ohio St.3d 155, 2017-Ohio-870, 73 N.E.3d 503, ¶ 38-40.
