decline as a result of $2.6 million in rent received but not recognized in rental revenues due to the re-classification of two sales-type leases starting January 1, 2024 described above.
Rental revenue received for the six months ended June 30, 2024 included the application of $0.6 million of security deposits for payment of rent, of which $0.5 million was replenished by a tenant in July 2024. Rental revenue received for the six months ended June 30, 2023 included the application of $5.7 million of security deposits for payment of rent.
While we have re-leased several properties taken back since March 2023, rent commencement on certain of those properties is contingent on the tenants obtaining the requisite approvals to operate, and temporary rent abatements in certain instances as tenants transition into the properties and commence operations. As a result, we do not expect to recognize rental revenue from those properties until that has occurred.
Other Revenues. Other revenues for the three and six months ended June 30, 2024 and 2023 consisted of interest revenue related to leases for property acquisitions that did not satisfy the requirements for sale-leaseback accounting.
Property Expenses. Property expenses for the three months ended June 30, 2024 increased by $1.1 million to $6.9 million, compared to $5.8 million for the three months ended June 30, 2023. Property expenses for the six months ended June 30, 2024 increased by $2.2 million to $13.6 million, compared to $11.4 million for the six months ended June 30, 2023. The increase in both periods was due to additional investment in existing properties, which resulted in higher property tax that we paid for our properties, as well as higher property expenses related to properties that we have taken possession of but not yet leased. Property expenses related to leased properties are generally reimbursable to us by the tenants under the terms of the leases.
General and Administrative Expense. General and administrative expense for the three months ended June 30, 2024 decreased by $0.9 million to $9.7 million, compared to $10.6 million for the three months ended June 30, 2023. General and administrative expense for the six months ended June 30, 2024 decreased by $1.7 million to $19.2 million, compared to $20.9 million for the six months ended June 30, 2023. The decrease in general and administrative expense for both periods was primarily due to lower litigation-related expense incurred during the period and lower compensation to employees. The lower compensation was primarily due to the expiration of the PSUs granted in 2021 on December 31, 2023 (which were forfeited in their entirety as they failed to meet the threshold for any payout as of that date), which was partially offset by increases to payroll salary, bonus expense and non-PSU related stock-based compensation for employee and directors. Compensation expense for the three and six months ended June 30, 2024 included $4.4 million and $8.7 million, respectively, of non-cash stock-based compensation. Compensation expense for the three and six months ended June 30, 2023 included $4.9 million and $9.7 million, respectively, of non-cash stock-based compensation.
Depreciation and Amortization Expense. Depreciation and amortization expense for the three months ended June 30, 2024 increased $0.8 million to $17.5 million, compared to $16.7 million for the three months ended June 30, 2023. Depreciation and amortization expense for the six months ended June 30, 2024 increased by $1.2 million to $34.6 million, compared to $33.4 million for the six months ended June 30, 2023. The increase in depreciation and amortization expense was primarily related to depreciation on properties that we acquired in 2023 and the placement into service of construction and improvements at certain of our properties.

Interest Income. Interest income for the three months ended June 30, 2024 increased by $1.7 million to $4.0 million, compared to $2.3 million for the three months ended June 30, 2023. Interest income for the six months ended June 30, 2024 increased by $1.2 million to $5.8 million, compared to $4.6 million for the six months ended June 30, 2023. The increase in both periods was primarily due to cash interest received on our construction loan agreement with a developer pursuant to which we agreed to lend up to $23.0 million (as amended), for the development of a regulated cannabis cultivation and processing facility in California (the “Construction Loan”). Cash interest received on our Construction Loan was $2.1 million during each of the three and six months ended June 30, 2024, versus $0.5 million during each of the three and six months ended June 30, 2023. Cash interest received on our Construction Loan included a loan maturity extension fee paid to us of $0.3 million during the three months ended June 30, 2024.
Interest Expense. Interest expense primarily consists of interest on our Notes due 2026. Interest expense for the three months ended June 30, 2024 decreased by $0.2 million to $4.3 million, compared to $4.5 million for the three months ended June 30, 2023. Interest expense for the six months ended June 30, 2024 decreased by $0.3 million to $8.7 million, compared to $9.0 million for the six months ended June 30, 2023.The decrease in both periods was primarily due to the capitalization of $0.2 million and $0.4 million of interest during the three and six months ended June 30, 2024, respectively, and the maturity of the Exchangeable Senior Notes in February 2024. The decrease was partially offset by $68,000 and $0.1 million non-cash interest expense related to the Revolving Credit Facility for the three and six months ended June 30, 2024, respectively. Interest expense for the three months ended June 30,
