Court allows interest deduction on loan for permanent residence but denies double interest on that debt.

The Administrative Court allowed the taxpayer to deduct interest on a loan used to purchase a permanent residence, but rejected the claim for additional interest on that same debt. The taxpayer argued that interest should be deductible on all related costs, while the tax authority limited deductions to the principal loan interest. The court ruled that while the primary interest is deductible, the secondary interest on the loan itself does not qualify for a separate deduction under the tax law.
