Key legal question
Whether amortization on the building was deductible for direct federal tax because the property belonged to business assets.
Extracted holding
No. The building was part of the taxpayer's private assets, so the claimed amortization was not deductible.
Extracted reasoning
The operation was ordinary management of private wealth: the taxpayer mainly worked as an employee, the simple partnership was not registered, and the building was leased to mixed commercial and residential tenants without showing an independent business activity linked to the property.
