Long-Term Debt [Text Block]	5. Long-Term Debt In 2023, the Company entered into a three-year financing agreement with a financial lending institution for an asset-based line of credit ("Credit Facility") with a maximum revolving credit of $7,000,000. The borrowing base under the Credit Facility is determined using 85% of eligible domestic and foreign accounts receivable balances, less any other specific reserves. In general terms, ineligible receivables are defined as invoices unpaid over 90 days. The balance outstanding on the Credit Facility is approximately $2,127,000 and $2,103,000 as of December 31, 2024, and 2023, respectively. The interest rate on the Credit Facility is equal to the greater of 8.0% or prime rate (as defined by JP Morgan Chase) plus 1.0% (8.5% and 9.5% as of December 31, 2024 and 2023, respectively). The Credit Facility is collateralized by the Company's non-realty assets. In accordance with ASC 470-10-45-5 Classification of Revolving Credit Agreements Subject to Lock-Box Arrangements and Subjective Clauses, borrowings outstanding under the Credit Facility that includes both a subjective acceleration clause and requirement to maintain a lock-box arrangement must be considered short-term obligations. As the Credit Facility includes both provisions, the outstanding balances are classified as current liabilities on the Condensed Consolidated Balance Sheets. The Credit Facility contains two financial covenants required to be maintained by the Company at the end of each of its fiscal quarters. The Tangible Net Worth covenant requires the Company to maintain tangible net worth not less than $20,000,000. The Working Capital covenant requires the Company to maintain working capital not less than $10,000,000. The Company met both covenant requirements as of December 31, 2024, and 2023.
