The County Supervisor may take the best lien obtainable on any real estate owned by the borrower, including any real estate which already serves as security for another loan. Additional liens will be taken only when the borrower is delinquent, the existing security is not adequate to protect Rural Development interests, and the borrower has substantial equity in the real estate to be mortgaged, and taking such mortgage will not prevent making a Rural Development real estate loan, if needed, later.
