In this action brought by the Chapter 7 trustee to avoid and recover a pre-petition transfer of funds from the debtors to their residential landlord as a preference, the court denied the trustee's motion for summary judgment. While the landlord's § 365(p) argument regarding the assumption of a personal property lease was inapplicable here, the affirmative defenses in the preference statute were viable. The debtors' pre-payment of a month's rent could be considered an substantially contemporaneous exchange for new value, while the lump-sum payment of a six-month arrearage requires a factual inquiry into whether that was part of the parties' ordinary course of business dealings or financial affairs.
