One year occupancy required?

[James A Hart]

Hello,

My brother and I recently purchased a duplex that was going to serve as his primary residence. Because of this, we applied for a "primary residence" loan. Since we bought the property, our dad became sick and my brother will now be living at home with him instead of moving into the new duplex. What are the laws around dealing with this in regards to the one year occupancy requirement on our mortgage?

Thanks for any help.
