Operating Costs (Bewirtschaftungskosten)

Ongoing expenses of property ownership

3 min readUpdated December 2024

Operating costs (Bewirtschaftungskosten) are the ongoing expenses of owning and maintaining an investment property. Unlike acquisition costs, these are annual and tax-deductible.

What's Included

Property Management:

Typically 8-12% of gross rent for full-service management (tenant finding, rent collection, maintenance coordination)

Maintenance & Repairs:

Reserve 1-2% of property value annually for upkeep (broken appliances, painting, etc.)

Administrative Costs:

Property tax (Grundsteuer), building insurance, HOA fees (Hausgeld) for condos

Vacancy Reserves:

Budget for 1-2 months of lost rent per year for turnover periods

Real Example: Annual Operating Costs

€450,000 Property (€1,800/month rent):

  • Property management (10%):€2,160
  • Maintenance reserve (1.5%):€6,750
  • Property tax:€1,275
  • Building insurance:€450
  • Vacancy reserve (1 month):€1,800
  • Total operating costs:€12,435/year

Tax savings at 42% bracket: €5,223 → Net cost: €7,212/year

Operating Expense Ratio

Industry rule of thumb: Operating costs typically consume 25-40% of gross rental income:

  • New properties: 15-25% (lower maintenance)
  • Mid-age properties: 25-35% (typical)
  • Older properties: 35-45% (higher repairs)

What's NOT Included

Operating costs don't include:
• Mortgage payments (that's financing cost)
• Acquisition costs (notary, transfer tax)
• Major renovations (these add to property basis)
• Utilities paid by tenant (Nebenkosten)

Minimizing Operating Costs

  • Self-manage: Save 8-10% by handling tenant relations yourself (not recommended for first property)
  • Buy newer properties: Lower maintenance in first 10-15 years
  • Screen tenants carefully: Good tenants = less turnover = lower vacancy costs
  • Set aside maintenance reserves: Avoid surprises and forced sales
