Susan begins construction of her dream home and grants Bank a mortgage to secure payment for a loan for the construction expenses. After construction is completed, Susan buys a well pumping system from Tyko which is installed on Susan’s property and connected to the home. Tyko takes a purchase money security interest in the well pumping system.

If Susan declares bankruptcy 5 days after the well-pumping system is installed, which of the following statements is true?

A. Assuming Bank recorded its mortgage before the well pumping system was installed, Bank would have priority over Tyko.

B. Assuming Tyko files a proper financing statement in the UCC records within 20 days of the well pump system being installed, Tyko would have priority over Bank.

C. If Susan granted Bank another mortgage after the well pumping system was installed and Bank recorded the additional mortgage that same day, then Bank would have priority over Tyko even if Tyko filed a proper fixture filing within 5 days of the well pump being installed.

D. If Tyko filed a proper fixture filing within 5 days of the well pump system being installed, then Tyko would have priority over Bank, even if Susan granted Bank another mortgage in the property after the well pump system was installed and Bank recorded the additional mortgage that same day.
