The lack of available financing is a major impediment to the construction of earth-sheltered housing. A broad-based study of lending institutions, this study describes the perceptions of loan officers toward earth-sheltered housing and their perception of their institution's lending policies in terms of their concerns. The survey finds that a majority of the loan officers perceive more stringent terms and larger down payments for earth-sheltered housing because of their concerns for financial risk, complexity, and relative advantage. Methods to reduce the risk and complexity and to increase the relative advantage would involve marketing research, certification and warranty programs, secondary mortgages markets, and other techniques. 8 references, 5 tables.
