facts involved, concluded that the sale price was a reasonably equivalent value. At that time, however, no evidentiary hearing had been conducted concerning the issue of reasonably equivalent value. Although the bankruptcy court and the district court focused on the total price received for the property at the sale, it is more accurate to consider the value received for Hulm’s interest, which comprised less than all rights in the property. This point is not of practical significance, however, since examination of the adequacy of the total sale price necessarily subsumes the issue of the adequacy of the value received for Hulm’s interest.
On appeal Hulm and the trustee contend that the district court erred in its determination that the sale price at the foreclosure sale was a reasonably equivalent value under 11 U.S.C. § 548(a)(2)(A). In its cross-appeal First Federal contends that the transfer of Hulm’s interest occurred when the mortgage was recorded and perfected under state law on November 29, 1978, more than one year before Hulm’s bankruptcy petition was filed. First Federal also contends that actual market value is irrelevant because absent a showing of fraud or collusion the sale price at a judicial foreclosure sale is a reasonably equivalent value for the property transferred as a matter of law.
The question of whether the judicial foreclosure of a mortgage effects a transfer within the meaning of section 548(a) is a question of federal law. See McKenzie v. Irving Trust Co., 323 U.S. 365, 369-70, 65 S.Ct. 405, 407-08, 89 L.Ed. 305 (1945). Thus, to aid in determining whether the foreclosure of the mortgage was a transfer of an interest of the debtor in property, we turn to the definition of transfer found in 11 U.S.C. § 101(41): “‘[T]ransfer’ means every mode, direct or indirect, absolute or conditional, voluntary or involuntary, of disposing of or parting with property or with an interest in property, including retention of title as a security interest.” If at the time of the mortgage foreclosure Hulm held an interest in the property, the language of section 101(41) clearly establishes that the mortgage foreclosure procedure in this case effected a transfer. Section 101(41) expressly includes involuntary transfers, and neither section 101(41) nor section 548(a) indicates that to fall within their terms the transfer had to be made by Hulm himself.
The term “interest of the debtor in property” is not defined in the Bankruptcy Code, however, and thus we look to state law to determine whether the debtor had an interest in property. See Butner v. United States, 440 U.S. 48, 55, 99 S.Ct. 914, 918, 59 L.Ed.2d 136 (1979); Johnson v. First National Bank of Montevideo, 719 F.2d 270, 273 (8th Cir.1983), cert. denied, — U.S. -, 104 S.Ct. 1015, 79 L.Ed.2d 245 (1984). We have no difficulty in concluding that under North Dakota law Hulm had an interest in the property at the time of its sale, and at least until expiration of the redemption period. The mortgage held by First Federal was only a defeasible conveyance giving it the right to satisfy Hulm’s unpaid debt from the property. See Pioneer Credit Co. v. Latendresse, 286 N.W.2d 445, 447 (N.D.1979). As a mortgagee, First Federal did not have a title interest in the property. Aure v. Mackoff 93 N.W.2d 807, 811 (N.D.1958). Hulm remained the legal owner of the property until foreclosure, and his interest was alienable. Knowlton v. Coye, 76 N.D. 478, 37 N.W.2d 343, 347 (1949). Hulm’s interest also included the right to possession of the property until the end of the redemption period, see N.D.Cent.Code § 28-24-11, and the right to the excess of the value of the property over First Federal’s mortgage, see N.D.CentCode § 32-19-10. At the foreclosure sale Hulm’s interest was transferred, subject to redemption. Hulm’s equity of redemption was likewise an interest in the mortgaged property which could be conveyed. See Robar v. Ellingson, 301 N.W.2d 653, 657 (N.D.1981). Issuance of the sheriff’s deed terminated Hulm’s interest in the property. See N.D.Cent.Code § 32-19-09.
