Nonaccrual loan | 1,800,000 | $ 1,300,000
Loans receivable, description |  | One loan totaling $248,000 was refinanced with $30,000 cash out because of cost overruns associated with construction of two four-plexes. This loan was part of an overall credit facility maintained for the construction project. The credit facility is secured by the project real estate as well as additional real estate. The loan was classified as a TDR because of payment delays experienced by the borrower. Subsequent to June 30, 2019, an updated appraisal showing adequate loan-to-value in support of the project was obtained. One loan totaling $75,000 was modified with $15,000 cash out and an extension of the loan term to enable the borrower to consolidate debts and establish acceptable debt service obligations after a period of unemployment.
