Risks and Uncertainties [Abstract]
Concentration of Credit Risk	Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash deposits and receivables. The Company places its deposits with financial institutions and other creditworthy issuers and limits the amount of credit exposure to any one party. For the year ended December 31, 2019, the Company had seven significant customers, five of which individually accounted for 23%, 23%, 16%, 14% and 10%, respectively, of operating lease revenue and two of which accounted for 57% and 38%, respectively, of finance lease revenue. For the year ended December 31, 2018, the Company had five significant customers, four of which individually accounted for 30%, 21%, 15% and 13%, respectively, of operating lease revenue and one of which accounted for 67% of finance lease revenue. At December 31, 2019, the Company had receivables from one customer totaling $828,000 related to rents for 2019, representing 74% of the Company’s total accounts receivable, all of which was for accrued rent that is due in March 2020. At December 31, 2018, the Company had receivables from three customers totaling $3,413,500, representing 87% of the Company’s total accounts receivable.
