Depreciation, depletion and amortization increased $0.5 million, or 7.7%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was driven by non-recurring adjustments in the second and third quarters of 2023 and more depreciable assets placed into service, partially offset by asset dispositions and more assets becoming fully depreciated.
Property operating expenses increased $0.5 million, or 5.7%, for the year ended December 31, 2023 compared to the year ended December 31, 2022, resulting from higher tax, insurance, and cost sharing on a West Coast farm, partially offset by lower utilities expense.
Cost of goods sold decreased $1.2 million, or 20.3%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease was the result of a lower volume of crop sold on citrus farms and the conversion of blueberry farms from direct operations to third party leases, partially offset by an increase in walnuts in the year ended December 31, 2023 compared to the year ended December 31, 2022.
Acquisition and due diligence costs remained relatively flat at $0.0 million and $0.1 million for the years ended December 31, 2023 and 2022, respectively.
General and administrative expenses decreased $0.7 million, or 6.1%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease was primarily driven by lower bonus, stock-based compensation and travel expense partially offset by higher payroll costs.
Legal and accounting expenses decreased $1.6 million, or 55.5%, for the year ended December 31, 2023 compared to the year ended December 31, 2022, due primarily to the successful defense and termination of the stockholder class action litigation that was pending against the Company from July 2018 until dismissal of the litigation by a federal judge on April 6, 2022.
Impairment of assets increased $5.8 million for the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was the result of certain properties being written down to their estimated fair value.

Other income decreased $0.6 million, or 94.1%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This decrease is primarily due to proceeds from a property insurance claim received during the year ended December 31, 2022, due to weather-related damage, partially offset by loss on early extinguishment of debt during the year ended December 31, 2022.
Income from equity method investment remained relatively flat at $0.0 million and $0.1 million for the year ended December 31, 2023 and 2022, respectively.
Gain on disposition of assets, net increased $33.5 million for the year ended December 31, 2023 compared to the year ended December 31, 2022, primarily due the appreciation of farmland value on properties sold relative to book value as well as a greater number of property dispositions during the year ended December 31, 2023 as compared to the year ended December 31, 2022. In connection with the sale of two farms in December 2023 pursuant to which we provided $9.5 million of seller financing, we deferred an additional net gain on sale of $2.1 million. The deferred gain will be recognized at such time as we consider collection of the seller-financed portion of the sale price to be probable under applicable accounting standards.
Interest expense increased $6.5 million, or 40.4%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. This increase was the result of an increase in interest rates, partially offset by a lower average balance on outstanding debt.
Income tax (benefit) changed from income tax expense of $0.2 million for the year ended December 31, 2022 to income tax benefit of $0.2 million for the year ended December 31, 2023. This change is due to tax adjustments of prior period estimates.
