The house was sold as a result of foreclosure on date A through trustees at an auction. The bank representatives bought it back, the deed is not registered with the MoCo Office of the Assessor yet. I assume, it will be registered on date B. When does property actually change hands? date A, date B or sometime else?
Practical implications: who is responsible for building maintenance between date A and the effective date of property ownership transfer? If there are tenants on the property, who is their landlord between date A and B?
