a larger impact on operating margin per compensated man-day. Accordingly, modest changes in occupancy can have a notable impact in our Community segment.
In January 2024, we completed the sale of the 120-bed Dahlia Facility, a residential reentry center in Denver, Colorado. We received gross sales proceeds of $8.0 million on the sale of the Dahlia facility compared to the carrying value of $7.5 million, resulting in a $0.5 million net gain on the sale after transaction related expenses, which was recognized in the first quarter of 2024. We continued to operate the Dahlia facility through the expiration of the management contract in June 2024. During our period of operation in 2024, this facility generated facility net operating income of $0.2 million.
In July 2024, we completed the sale of the idled 390-bed Tulsa Transitional Center, a residential reentry center in Tulsa, Oklahoma. We received net sales proceeds of $3.4 million on the sale of the Tulsa property, resulting in a gain on sale of $1.2 million, which was recognized in the third quarter of 2024.
CoreCivic Properties
CoreCivic Properties includes the operating results of the properties we leased to government agencies during each period. Total revenue generated by CoreCivic Properties decreased $8.4 million, or 64.4%, from $13.0 million during the three months ended March 31, 2024 to $4.6 million during the three months ended March 31, 2025. CoreCivic Properties' facility net operating income decreased $7.7 million, or 83.5%, from $9.2 million during the three months ended March 31, 2024 to $1.5 million during the three months ended March 31, 2025. The decreases in total revenue and net operating income were primarily the result of the termination of the lease at our California City Facility effective March 31, 2024, as further described hereinafter. During the three months ended March 31, 2025, CoreCivic Properties generated 3.1% of our total segment net operating income, compared with 9.1% during the three months ended March 31, 2024.
On December 6, 2022, we received notice from the California Department of Corrections and Rehabilitation, or CDCR, of its intent to terminate the lease agreement for our 2,560-bed California City Facility by March 31, 2024, due to the state's declining inmate population. The California City Facility was idled effective April 1, 2024. Rental revenue generated from the CDCR at the California City Facility was $8.5 million during the three months ended March 31, 2024. Facility net operating loss was $0.9 million and facility net operating income was $7.2 million during the three months ended March 31, 2025 and 2024, respectively, including carrying expenses we continue to incur post lease termination. Effective April 1, 2025, we entered into a letter agreement with ICE to begin activation efforts at the California City Facility. The letter agreement authorizes initial funding up to $10.0 million with maximum funding up to $31.2 million for a six-month period while we work to negotiate and execute a long-term contract. Because we are operating the facility rather than leasing it, we currently expect that the California City Facility will transition from our Properties segment to our Safety segment during the second quarter of 2025.
General and administrative expenses
For the three months ended March 31, 2025 and 2024, general and administrative expenses totaled $36.0 million and $36.5 million, respectively. General and administrative expenses consist primarily of corporate management salaries and benefits, professional fees, and other administrative expenses.
Depreciation and amortization
For the three months ended March 31, 2025 and 2024, depreciation and amortization expense totaled $30.5 million and $31.7 million, respectively. Depreciation and amortization expense decreased primarily as a result of certain assets, including certain information technology assets, becoming fully depreciated. In addition, we have begun to make more investments in "software as a service", or SaaS, technology, which reduces our need to install, maintain, and update certain software applications.
Interest expense, net and expenses associated with debt repayments and refinancing transactions
Interest expense is reported net of interest income and capitalized interest for the three months ended March 31, 2025 and 2024. Gross interest expense was $18.4 million and $22.1 million for the three months ended March 31, 2025 and 2024, respectively Gross interest expense was based on outstanding borrowings under our revolving credit facility, or Revolving Credit Facility, our outstanding term loan, or Term Loan, or collectively, our Bank Credit Facility, our outstanding senior unsecured notes, and our outstanding non-recourse mortgage note, as well as the amortization of loan costs and unused facility fees. Gross interest income was $3.2 million and $3.4 million for the three months ended March 31, 2025 and 2024, respectively. Gross interest income is earned on notes receivable, investments, cash and cash equivalents, and restricted cash. Interest income also includes interest income associated with the 20-year finance receivable associated with the Lansing Correctional Facility lease to the Kansas Department of Corrections, which commenced in January 2020, and amounted to $2.0 million and $2.1 million for the three months ended March 31, 2025 and 2024, respectively.
