The Baufinanzierung (mortgage financing) is the biggest financial decision of your life. Over a term of 25–35 years, even a 0.3 % difference in interest amounts to several thousand euros. This guide shows how to find the best financing, with concrete figures for 2026.
1. Current interest rate situation in 2026
After the interest rate peak of 2023/24, mortgage rates settled at a middling level in 2026. The values below are guidance values only. Actual offers vary from day to day, depending on your creditworthiness, the loan-to-value ratio and the bank:
| Zinsbindung (fixed-rate period) | approx. interest rate | Recommendation |
|---|---|---|
| 5 years | 2.8–3.2 % | Only if a sale is planned |
| 10 years | 3.2–3.8 % | Standard recommendation |
| 15 years | 3.5–4.0 % | Good with little equity |
| 20 years | 3.8–4.3 % | Maximum planning certainty |
2. The Zinsbindung is a decision of its own
Most buyers negotiate the interest rate and take the Zinsbindung (the fixed-rate period) as a given. That is the wrong way round. The Zinsbindung determines how much of your loan is exposed to interest rate risk at all. With a long fixed-rate period you are buying insurance, and the surcharge in the table above is the premium.
What makes it special: the insurance is one-sided. § 489 (1) no. 2 BGB lets you terminate any property loan ten years after it has been fully paid out, with six months' notice and without a Vorfälligkeitsentschädigung (early repayment penalty). So you are free after ten and a half years at the latest, even if the contract says 20 years. If rates fall, you get out. If they rise, you stay in the long fixed-rate period. The bank has no such right.
The cost of that option can be quantified. Take 300,000 € and a 2 % initial repayment rate. If you pay 0.6 points more than 3.5 % for the long fixed-rate period but keep the same monthly instalment, after ten years you are left with around 20,000 € more residual debt, because that money went into interest instead of repayment. That is the price of planning certainty. Whether it is worth it depends entirely on how much residual debt is still open after ten years.
3. Choosing the right repayment rate
The Tilgung (repayment rate) determines how quickly you become debt free. Basic rule: an initial repayment rate of at least 2 %, better 3 %. The lower the repayment rate, the longer the loan runs, and the more interest you pay in total.
| Repayment rate | Monthly instalment | Term | Interest paid |
|---|---|---|---|
| 1 % | 1,125 € | ~43 years | ~281,000 € |
| 2 % | 1,375 € | ~29 years | ~178,000 € |
| 3 % | 1,625 € | ~22 years | ~131,000 € |
| 4 % | 1,875 € | ~18 years | ~105,000 € |
4. Interest rate risk: the residual debt is the number that matters
When the fixed-rate period ends, the loan is not paid off. It has to be refinanced at an interest rate that is unknown today. This is exactly where it is decided whether a financing plan was sound. And it is exactly the number that no comparison portal puts first.
Let us work through the standard example: 300,000 €, 3.5 % interest, 2 % initial repayment, instalment 1,375 €, fixed-rate period 10 years. Over ten years you transfer 165,000 € to the bank. Of that, only around 72,000 € is actual repayment, the rest is interest. The residual debt stands at around 228,000 €.
| Scenario | Monthly instalment | Remaining term from year 10 |
|---|---|---|
| Rate stays at 3.5 % | 1,375 € | ~19 years |
| 5.5 %, instalment unchanged | 1,375 € | ~26 years |
| 5.5 %, term unchanged | ~1,620 € | ~19 years |
Two extra interest points therefore mean either around 245 € more per month or seven additional years of debt. Anyone who cannot manage the instalment ends up selling under pressure. The most effective protection is not a longer fixed-rate period but a higher repayment rate: with 3 % instead of 2 % initial repayment, the residual debt after ten years is around 192,000 € instead of 228,000 €.
Forward-Darlehen: locking in a rate in advance
With a Forward-Darlehen (forward loan) you agree today on the interest rate for your follow-up financing, at many banks up to 60 months before the fixed-rate period ends. In return the bank charges a premium on the current rate that grows with every month of lead time, usually in the range of a few hundredths of a percentage point per month, depending on the provider and its rate expectations.
5. Beleihungsauslauf: the lever many people miss
Banks do not work with the purchase price but with the Beleihungswert (mortgage lending value): the amount they could realistically recover in a forced sale. To get there they deduct a safety margin from the purchase price, usually 10 to 20 %. The Beleihungsauslauf (loan-to-value ratio) is then your loan divided by that mortgage lending value.
Example: purchase price 400,000 €, safety margin 10 %, so the mortgage lending value is 360,000 €. With a loan of 300,000 € the loan-to-value ratio is around 83 %. Put in 40,000 € more equity and it drops to around 72 %. Jumps like these are decisive, because banks price their rates in tiers, typically at 60 %, 80 %, 90 % and above. Anyone just above a tier pays the higher rate on the entire loan.
6. Agreeing on Sondertilgung (special repayment)
Sondertilgung (special repayment) allows unscheduled repayments, for example from a bonus, an inheritance or a pay rise. Standard: 5 % of the loan amount per year free of charge. With a loan of 300,000 € that is up to 15,000 € of extra repayment per year.
Why the right has to be written into the contract explicitly: without an agreed Sondertilgung, the bank may refuse early repayment during the fixed-rate period or demand a Vorfälligkeitsentschädigung (early repayment penalty). It compensates the bank for the interest it loses and can run to several thousand euros on larger amounts. A free special repayment option removes exactly that obstacle.
The effect is bigger than it looks, because every special repayment saves interest for the entire remaining term. 5,000 € that you repay extra today saves you around 4,950 € in interest at 3.5 % over 20 remaining years. The amount almost doubles.
7. Watch out for Bereitstellungszinsen (commitment interest)
If you do not draw down the loan in full straight away (for example with a new build or a staggered purchase), Bereitstellungszinsen (commitment interest) apply, usually 0.25 % per month on the amount not yet drawn. That is 3 % a year, more than the loan interest itself.
Worked example: on a new build, 200,000 € stays undrawn for four months. 200,000 € × 0.25 % × 4 months = 2,000 € of pure commitment interest, for which you get nothing in return. So negotiate at least 6, better 12 months free of commitment interest. For a new build with an uncertain construction schedule, even 18 months is a legitimate negotiating goal, and usually cheaper to obtain than an interest rate that is 0.1 points better.
8. Right of withdrawal: a 14-day safety net
A property loan to a consumer is a Verbraucherdarlehensvertrag (consumer loan agreement). Under § 495 BGB you can withdraw from it within 14 days, without giving reasons. The period only starts once you have received the contract and all the mandatory statutory information. For consumer property loans the right of withdrawal expires at the latest twelve months and 14 days after the contract was concluded, even if the withdrawal notice was faulty (§ 356b BGB).
9. Where to compare financing offers?
Obtain at least 3 offers before you commit:
- Your own bank: Knows your creditworthiness, often not the best rate. But useful as a basis for negotiation.
- Brokers: Interhyp, Dr. Klein, Baufi24, they compare hundreds of banks. Free for the borrower (commission comes from the bank).
- Direct banks: ING, DKB, Commerzbank, often good terms with a straightforward assessment.
- KfW loans: Apply through your own bank, not directly at the KfW. See the KfW funding guide.
10. Which documents the bank wants to see
A financing commitment hinges on two questions: can you pay (creditworthiness), and is the property worth the security it provides (property value)? The bank wants paperwork for both. Anyone who arrives fully prepared gets a binding offer faster, and in a bidding process that is a real advantage.
- ☐ Proof of income (last 3 payslips + latest tax assessment)
- ☐ If self-employed: annual accounts for the last 2 to 3 years and a current BWA (interim business report)
- ☐ Proof of equity (bank statements, securities account, Bausparvertrag)
- ☐ SCHUFA report (free via meineSCHUFA.de)
- ☐ Selbstauskunft (self-disclosure): monthly income and expenses, existing loans
- ☐ Exposé (property brochure) and the notary's draft purchase contract
- ☐ Current Grundbuchauszug (land register extract) and cadastral map / site plan
- ☐ Floor plans, living area calculation, building specification, photos
- ☐ Energieausweis (energy performance certificate)
- ☐ For a flat: Teilungserklärung (declaration of division), business plan, minutes of the owners' meetings
11. Typical mistakes when comparing
Mistake 1: comparing the nominal rate instead of the effective rate. The Nominalzins is the pure loan interest. The effektiver Jahreszins (annual percentage rate) also factors in how often the bank credits your repayments and whether a discount (Disagio) or processing fees apply. Two offers with an identical nominal rate can have different effective rates. Always compare the effective rate.
Mistake 2: trusting the effective rate blindly. It does not contain everything. Commitment interest, valuation and appraisal fees and the notary's costs for registering the Grundschuld (land charge) are not included. So always ask about the incidental costs of the financing. What else is added on top when buying is covered in the guide Incidental purchase costs.
Mistake 3: comparing offers with different repayment rates. An offer at 3.4 % with 2 % repayment looks cheaper next to 3.5 % with 3 % repayment, because the monthly instalment is lower. But you pay the loan back more slowly and have more residual debt when the fixed-rate period ends. Offers only become comparable when the loan amount, fixed-rate period, repayment rate and special repayment right are identical. The decisive figure for comparison is then the residual debt at the end of the fixed-rate period.
