Financing a Home in Germany: How to Plan It Right

From budget planning to financing to additional purchase costs: how to finance your home in Germany.

Reading time: 10 min.

Financing a home – one of the biggest financial decisions of your life. Loans of over €200,000, terms of 20-30 years: every detail has to be right. Equity, the fixed-rate period, repayment, KfW support – this guide shows you how to plan your financing correctly and avoid typical mistakes.

Key takeaways

  • Spend a maximum of 30-35% of your net income on housing
  • Equity: at least the additional purchase costs (10-15%), ideally 20-30%
  • Initial repayment rate: at least 2%, ideally 3% or more
  • Fixed-rate period: 15-20 years for maximum planning security

How Much House Can You Afford?

Before you start looking for a property, you need to know your budget. The rule of thumb: do not spend more than 30-35% of your net household income on housing.

Budget Calculation: An Example

  • Net household income: €5,000/month
  • Maximum burden (33%): €1,650/month
  • Minus utilities (approx. €350): €1,300 for the instalment
  • At 3.5% interest + 2% repayment (= 5.5% p.a.): approx. €285,000 loan
  • Plus equity (€80,000): €365,000 purchase budget
  • Minus additional purchase costs (12%): approx. €325,000 property price

Planning for Additional Purchase Costs

A common mistake: underestimating the additional costs. They make up 10-15% of the purchase price and are largely "lost" – they do not go into the property itself.

The Additional Costs in Detail

  • Property transfer tax: 3.5-6.5% depending on the state
    Bavaria/Saxony: 3.5% | North Rhine-Westphalia/Brandenburg: 6.5%
  • Notary and land registry: approx. 1.5-2%
  • Broker commission: 3-7.14% (often split equally)
  • Appraiser, if applicable: €500-1,500

Example: €400,000 Purchase Price in North Rhine-Westphalia with a Broker

  • Property transfer tax (6.5%): €26,000
  • Notary + land registry (2%): €8,000
  • Broker (3.57%): €14,280
  • Total: approx. €48,280 (12%)

Equity: How Much Do You Need?

The more equity you have, the better your interest rate conditions and the more secure your financing. But how much is enough?

The Rule of Thumb

Minimum: the additional purchase costs (10-15%)
Better: 20-30% of the purchase price plus additional costs
Optimal: 40%+ of the purchase price plus additional costs

Equity Tip

20% equity plus the additional purchase costs is considered a solid basis. With less equity, interest rates and risk increase significantly.

Why More Equity Is Better

  • Better interest rates: 0.2-0.5% cheaper at 30% vs. 10% equity
  • Lower instalment: less debt means a lower monthly burden
  • Debt-free sooner: less interest, more repayment
  • More security: a buffer in case of a loss in value or loss of income

Use the mortgage calculator to compare different equity scenarios.

What Counts as Equity?

  • Cash, overnight deposits, fixed deposits
  • Stock portfolio (with a discount for volatility)
  • Building society savings contract (ready for allocation)
  • Sweat equity ("Muskelhypothek"): 5-15% of construction costs
  • Gifts or inheritances
  • An existing property (as collateral)

Finding the Right Financing

There are various types of loans for home financing. The most common: the annuity loan.

Annuity Loan

The instalment (annuity) stays the same throughout the entire fixed-rate period. At the start you pay more interest, later you pay more repayment. The classic choice for homebuyers.

Building Society Savings Contract

Save first, then take out a loan. The advantage: interest rate security from the start. The disadvantage: a long savings phase that is often no longer up to date. As a supplement (an alternative to a forward loan), it can still make sense.

KfW Loan

State-subsidized loans for energy-efficient building and renovation. Often lower interest rates and repayment subsidies. Must be applied for through your bank.

Comparing Pays Off!

Even a 0.2% difference in interest adds up to approx. €12,000 on €300,000 over 20 years. Get at least 3 offers – a bank, a savings bank (Sparkasse) and an independent broker (Interhyp, Dr. Klein).

Repayment and the Fixed-Rate Period

Two important levers in your financing: how much you repay each month and how long your interest rate is fixed.

Initial Repayment Rate

At least 2%, ideally 3% or more. With a 1% repayment rate and 3.5% interest, it takes over 40 years to become debt-free. With a 3% repayment rate, it takes only about 23 years.

The Fixed-Rate Period

Common terms: 10, 15, 20 or 25 years. The longer the term, the higher the interest rate premium (approx. 0.3-0.5% per 5 years). But: you are protected if interest rates rise.

Rule of Thumb for the Fixed-Rate Period

Choose a fixed-rate period so that at most 10-20% of the loan amount is still outstanding when it ends. This minimizes your interest rate risk for the follow-up financing.

Using Government Support Programs

The government supports buying a home with several programs. The most important:

KfW Support

The KfW (Germany's state-owned development bank) offers low-interest loans and repayment subsidies for energy-efficient building and renovation. Particularly attractive: KfW 300 (home ownership for families) with up to €240,000 in loans on top terms.

Wohn-Riester

You can use your Riester savings to buy a home or use Riester allowances toward your repayment. Advantage: allowances and tax savings. Disadvantage: deferred taxation in retirement.

State Support Programs

Many German states (Bundesländer) have their own programs for families, young people or specific regions. Conditions vary widely – check with the relevant state bank (e.g. NRW.Bank, L-Bank, LfA Bayern).

Employee Savings Allowance

If your employer pays capital-forming benefits (vermögenswirksame Leistungen, VL) and you put them into a building society savings contract, you can receive a state allowance. Up to 9% on €470/year (= €43 per year).

Frequently Asked Questions About Financing a Home

Frequently Asked Questions

You should bring at least the additional purchase costs (10-15%) as equity. Better: 20-30% of the purchase price plus additional costs. For a purchase price of €400,000, that means €80,000-120,000 in equity plus approx. €40,000 for additional costs. The more equity you have, the better your interest rate conditions.

Rule of thumb: a maximum of 30-35% of your net household income. At €4,000 net, that would be €1,200-1,400. Also budget an additional €2-3/sqm for utilities (heating, electricity, property tax, insurance) and €1/sqm for maintenance.

Both matter! A higher repayment rate (at least 2%, ideally 3%) reduces the remaining debt faster and saves interest in the long run. A longer fixed-rate period (15-20 years) protects you against rising interest rates. In the current environment: a 15-year fixed-rate period with a 2-3% repayment rate is preferable to a 10-year period with a high repayment rate.

In theory, yes (110% financing including additional costs), but it is very expensive and risky. Interest rates are noticeably higher, the instalment puts a heavy strain on your budget, and if the property loses value you can quickly end up "underwater". Better: save up equity first.

The most important: KfW subsidized loans (especially for energy-efficient new builds/renovations), Wohn-Riester (allowances and tax benefits), state support programs (depending on the Bundesland), the employee savings allowance on a VL building society contract. Conditions change regularly – check with your bank for the latest terms.
