Quote from @Damon Silver: Can you clarify "you can't have another separate tenant live there?" 

You should have, or you should create an amortization table that shows the actual interest paid on the $650k mortgage for the first 6 months while you lived there.

What zoning code could I request a zoning variance or rezoning that would allow us to have the 2 livable units on parcel, one primary residence and one additional living unit (known currently as ADU)?
