Stanley Matthews, Easton v. German-American Bank…
“ He is in the position of a trustee to sell, and is, by a familiar maxim of equity, forbidden to purchase for his own use at his own sale. The same principle applies, with a like result, where real estate is conveyed by a debtor directly to a creditor as security for the payment of an obligation, with a power to sell in case of default. There the creditor is also a trustee to sell, and cannot purchase the property at his own sale for his own use. ”
