Renting farmland

[ddwilkins67]

Own a small farm with land we cash lease to farmer and a house that is now our primary home. Prior we rented house and land so I split the taxes and interest between the 2 types.  I no longer rent the house; live in it full time.  Can I take all the mortgage interest for the house and only use the tax tax expense up[ to what I get in rent for the land or do I have to use a % spread across the primary use house and the rented land? If I divide it I am generating  a loss every year on the land.

Probably allocate across the land and house by assigning a value to each.
