Financing Costs (Finanzierungskosten)

Interest and fees for your mortgage

3 min readUpdated December 2024

Financing costs (Finanzierungskosten) are all expenses related to obtaining and maintaining your mortgage. The good news: nearly all of them are tax-deductible for investment properties.

What Counts as Financing Costs?

One-Time Costs:

  • • Loan origination fees (Bearbeitungsgebühr)
  • • Property valuation (Wertgutachten)
  • • Loan broker commission
  • • Building insurance setup

Ongoing Costs:

  • • Mortgage interest (largest component)
  • • Annual account management fees
  • • Early repayment penalties (Vorfälligkeitsentschädigung)

Real Example: Total Financing Costs

€450,000 Property with 90% Financing (€405,000 loan):

Upfront Costs:

  • Property valuation:€800
  • Building insurance (annual):€450
  • Total upfront:~€1,250

Annual Costs (Year 1):

  • Mortgage interest (4.4%):€17,820
  • Building insurance:€450
  • Total annual:€18,270

Tax deduction (42% bracket): €7,673 tax savings

Net cost after tax: €10,597

Interest: The Biggest Component

Mortgage interest typically accounts for 95%+ of your annual financing costs. On a €405,000 loan at 4.4%, that's €17,820/year—but it's fully tax-deductible.

Strategic Insight: Leverage Makes Costs Worthwhile

Yes, €18,270/year in financing costs seems expensive. But you're controlling a €450,000 asset with only €45,000 down. If the property appreciates 3% (€13,500) plus rental income, you're ahead—even after financing costs.
