METRO LAND HOLDINGS INVESTMENTS, LLC et al.
v.
BANK OF AMERICA, N.A.
No. A11A1285.
Court of Appeals of Georgia.
August 24, 2011.
*567 King & Spalding, Philip Robbins Green, Schreeder, Wheeler & Flint, John A. Christy, Atlanta, for appellants.
Troutman Sanders, Thomas Edward Reilly, Claiborne Benson Smith, Atlanta, for appellee.
MIKELL, Judge.
This case arises from the applications for confirmation of four foreclosure sales filed pursuant to OCGA § 44-14-161 by Bank of America, N.A. ("the Bank") against Metro Land Holdings Investments, LLC ("Metro Land"), JFD Builders, LLC and Loomis E. Deavours ("Appellants"), who guaranteed the underlying promissory notes.[1] Appellants appeal the trial court's final order confirming the sale of the four properties contending that the third property was not purchased at its true market value (as required by OCGA § 44-14-161(b)). For the reasons that follow, we affirm.
In confirming a nonjudicial foreclosure sale under OCGA § 44-14-161, the trial court "shall require evidence to show the true market value[2] of the property sold under the powers and shall not confirm the sale unless it is satisfied that the property so sold brought its true market value on such foreclosure sale."[3] The trial judge in a confirmation proceeding "sits as the trier of fact, and its findings and conclusions have the effect of a jury verdict."[4] Thus, "witness credibility and the weight of the evidence proffered by the parties at a confirmation hearing are to be judged by the trial court, and not this Court on appeal."[5] For this reason, we will not disturb the trial court's decision if there is any evidence to support it,[6] and we view the evidence in the light most favorable to the trial court's judgment.[7]
So viewed, the record shows that in 2006, Metro Land executed four promissory notes in favor of the Bank. Each promissory note was secured by lots of undeveloped property in the Summerlake and Bramlett Station subdivisions in Gwinnett County, as evidenced by the Deeds to Secure Debt and Security Agreements. Metro Land defaulted on the notes, and the Bank elected to declare the outstanding debt immediately due and payable. The Bank then foreclosed on the properties under power of sale provisions contained in the deeds to secure debt. On July 7, 2009, the four properties were sold at auction at separate foreclosure sales in Gwinnett County. In the third foreclosure sale, the Bank, as lienholder, purchased a parcel of eight undeveloped residential lots in the Summerlake subdivision in Gwinnett County for $233,850.
*568 On July 29, 2009, the Bank reported the sales to a judge in the Superior Court of Gwinnett County and applied for confirmation of the four sales pursuant to OCGA § 44-14-161. Following a hearing, the superior court confirmed the sales. This appeal follows.
Appellants' sole enumeration of error is that the trial court erred in finding that the third property sold for its true market value because the written appraisal of the Bank's expert exceeded the amount bid by the Bank at the foreclosure sale.
At the hearing, the Bank presented the expert testimony of Scott R. Tonneson, an MAI-designated independent real estate appraiser, on the issue of true market value. Appellants called no witnesses and provided no expert testimony to rebut Tonneson's testimony as to valuation. Tonneson testified that he utilized a "Development Approach" in appraising the property based on its use as residential lots. According to Tonneson, this methodology requires a two-step process: first, the retail value of each lot is determined, and second, appropriate expenses and absorption rates are deducted from the retail value to arrive at the true market value.
Tonneson's written appraisal valued the eight lots comprising the third property at $237,551 as of July 7, 2009, an amount higher than the $233,850 foreclosure sale price. However, he stated at the hearing that he had revised his opinion subsequent to drafting the written appraisal because data he later obtained indicated that residential properties in the area were experiencing decreased sale prices and absorption rates during the last six months of 2009, and that this subsequent data was relevant to his valuation of the third property as of the sale date. Tonneson's revised opinion of the true market value of the third property is approximately $234,000 or $29,200 per lot.[8] Tonneson explained that the written appraisal reflected an inflated true market value because a review of subsequent sales in the area revealed a downward trend in the value of undeveloped lots. Tonneson explained that his review of these comparable bulk sales and absorption rates revealed that his "value conclusion [in his written appraisal] was . . . very high at the date of value" because there was "minimal demand and . . . excess supply" of residential lots in that area. Tonneson then went on to opine that, based on this downward trend, the fair market value of the third property as of the date of the foreclosure sale could be as little as $25,000 per lot, or $200,000 for the third property as a whole.
On appellate review, "the test is not whether this court would have accepted appellant's expert appraisals as the most reliable and accurate, but whether the record contains any evidence to support the findings of the trial court that the property brought its true market value at the foreclosure sale."[9] Further, "Georgia law has long held that the trier of fact may believe or disbelieve all or any part of the testimony of any witness."[10] Tonneson "provided the court with the basis for his opinions. As it appears that his opinion was not based on sheer speculation, an appellate court cannot second guess any methodology utilized to reach the opinion."[11] Appellants did not provide any evidence or expert testimony to rebut Tonneson's appraisal, and the trial court was entitled to believe Tonneson's expert opinion that the fair market value of the third property as of the date of the foreclosure sale was lower than his initial written appraisal because of a downward trend in the real estate market. Given the foregoing, the record contained sufficient evidence to permit the trial court to determine that the Bank's winning bid at the foreclosure sale brought at least the true *569 market value of the property.[12]
Judgment affirmed.
