During the second quarter, the Resident Relief Funds paid approximately $10.4 million to approximately 8,200 Camden residents. Of this amount, approximately $9.1 million was paid to approximately 7,100 residents of our wholly-owned communities and recorded as a reduction of property revenues, and approximately $1.3 million was paid to approximately 1,100 residents of the operating communities owned by our unconsolidated joint ventures. For the amounts paid to residents of the operating communities owned by our unconsolidated joint ventures, we recognized our ownership interest of $0.4 million in equity in income of joint ventures. Additionally, we also made arrangements to defer payments over existing lease terms for many of our residents and tenants. For the deferred rent payment plans offered, we recognize property revenue on the existing straight-line basis over the remaining lease term and recognize any changes in payment through lease receivables, which is recorded in other assets, net, in our consolidated balance sheets; any identified uncollectible amounts related to deferred amounts are presented as an adjustment to property revenue.</span></div><div style="margin-bottom:6pt;text-align:justify;text-indent:22.5pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">As of December 31, 2020, our average residential lease term was approximately fourteen months with all other commercial leases averaging longer lease terms.

In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.</span>
