Buying a home in Germany: rules and costs
- Property transfer tax (Grunderwerbsteuer) is set by each federal state and ranges from 3.5% (Bavaria) to 6.5%.
- Notary and land registry fees typically add 1.5–2% of the price.
- Most loans fix the rate for 10–15 years (Zinsbindung); a borrower can always terminate a fixed-rate loan 10 years after payout with 6 months' notice (§ 489 BGB).
- Many loans allow yearly special repayments (Sondertilgung), often up to 5% of the original amount — use the yearly extra payment field to model it.
- When a broker is involved, the buyer's share of the commission is capped at half, typically up to 3.57% including VAT.

Frequently asked questions
How is the monthly mortgage payment calculated?
For an equal-payment loan, the payment is P × i × (1 + i)^n ÷ ((1 + i)^n − 1), where P is the loan amount, i the monthly interest rate and n the number of months. Taxes, insurance and fees are added on top.
What is the current average mortgage rate in Germany?
The latest official figure is 4,01% for New housing loans (avg. agreed rate) (Aug 2026, source: European Central Bank, MFI interest rate statistics). Your own rate depends on your deposit, income, credit history and lender.
How much does a 1-point rate rise change my payment?
On a €320,000 loan over 30 years, going from 4,01% to 5,01% raises the monthly payment from €1,530 to €1,720 — about €190 more each month.
What upfront costs should I budget for in Germany?
On a €400,000 purchase, expect about €42,280 in taxes and fees on top of your down payment. The breakdown is shown in the calculator above.
Can this calculator predict future interest rates?
No. The scenario tool shows a range of possible outcomes based on the band you choose. Nobody can predict rates reliably — use it to check whether you could still afford the loan if rates rise.
