How Luxembourgers Can Budget for Investment Property in Germany

For many Luxembourgers, buying property in Germany looks like a perfect opportunity. Prices are often lower than in Luxembourg, and the border makes it convenient for commuters.

However, the first real step is to budget for investment property in Germany. Too often, buyers focus only on the purchase price and later discover the extra costs waiting for them. That includes things like notary fees, property transfer taxes, insurance, and regular maintenance.

In addition, banks in Luxembourg and Germany apply different rules when checking affordability, which can affect how much you can borrow. This guide will help you plan your budget step by step, understand deposits and hidden costs, and compare financing options across borders so you can approach your investment with confidence.

Why Budgeting Matters When Investing in Germany

Affordability in German property financing isn’t just about the price of the home. Banks want to know how much of your income can realistically go toward repayments, and most set the limit at about 35% of your net monthly income. If you earn €3,000 a month, that means your repayment would usually be capped at around €1,050.

The loan, however, is only part of the picture. The cost of buying a house in Germany can add another 8–15% on top of the purchase price. Buyers need to plan for expenses like the property transfer tax (3.5–6.5%, depending on the state), notary and land registry fees (1.5–2%), and sometimes an estate agent’s commission (up to 3.57%).

What often catches people off guard is that banks usually finance only the property itself. Those extra costs have to be paid out of pocket. And if you’re buying from abroad without being a German resident, lenders may also ask for a larger deposit, sometimes as high as 40% of the property’s value.

How Much Deposit Do You Need for a House in Germany?

If you are asking, How much deposit do I need for a house in Germany, the answer completely depends on your situation.

For most buyers, the standard is about 20% of the property’s value. On a €300,000 home, that works out to around €60,000. This applies to many residents and also to foreign buyers who qualify for a mortgage in Germany.

For Luxembourgers and other EU citizens who live or work in Germany, banks can sometimes be more flexible. Some lenders offer 100% financing, which means you don’t need to provide a deposit. Still, this usually covers only the property price. The extra costs, such as notary fees and the property transfer tax, will need to be paid from your own savings.

If you are buying as a non-resident, the rules are a bit more stricter. In many cases, banks will finance only about 60% of the property’s value, leaving you to provide the remaining 40% yourself, plus the other costs on top.

In the end, the deposit you’ll need comes down to your residency status and the bank’s conditions. Knowing this in advance helps you plan sensibly and avoid unexpected roadblocks.

How Much Can I Afford to Buy a House in Germany?

One of the common concerns of any buyer is, How much can I afford to buy a house in Germany? And the answer is not the same for everyone. It depends on your income and how banks measure your affordability.

A common rule is to take your net annual income and multiply it by 10. For example, if you earn €50,000 after tax, you might qualify for a mortgage of around €500,000.

Another way banks check affordability is by looking at your monthly repayment. Most prefer that your mortgage stay under 35% of your net income. If you take home €3,500 per month, your maximum repayment would be about €1,225.

It’s also worth noting that German households already spend about 25% of their disposable income on housing. That’s why it makes sense to leave yourself a buffer and avoid stretching your budget too tightly.

Taxes and Fees That Affect Your Budget

When you start planning to buy a home in Germany, the purchase price is just only the beginning. There are several other costs that you will need to prepare for.

The biggest one is the property transfer tax (Grunderwerbsteuer). This is a one-time tax based on the purchase price, and the rate depends on where the property is located. It usually falls between 3.5% and 6.5%.

You will also have to pay notary and land registration fees, which are required to make the purchase official. These typically add about 2% of the property’s value.

And, after you have bought the property, there are the ongoing costs to think about. If you plan to rent it out, rental income tax will apply. On top of that, you’ll want to budget for home insurance and regular maintenance to protect your investment.

A question that comes up often is: How can I avoid capital gains tax in Germany on property? The rules are fairly straightforward.

If you keep the property for 10 years or more, you can sell it tax-free, even if you live outside Germany. And if it’s been your main residence for at least two full calendar years, you’re also exempt, even if you’ve owned it for less than ten years.

Budgeting Steps for Luxembourgers

Step 1: Check what you can afford
Start by looking at your income, which gives you an idea of the loan size you might qualify for. Banks also expect repayments to stay under about 35% of your monthly income, so that’s another thing to keep in mind.

Step 2: Plan for deposits and fees
Most buyers need a deposit of around 20% of the property value. On top of that, you will face extra costs such as transfer tax and notary and registration fees. If you are buying as a non-resident, some banks may ask for closer to 40%, so it pays to prepare early.

Step 3: Compare banks on both sides
Financing conditions differ in Luxembourg and Germany. Some banks even offer 100% financing, though fees aren’t included. Smart Finance helps Luxembourgers navigate cross-border property financing in Germany and Luxembourg and find the option that fits best. These steps give you a clear budget and a plan you can trust.

Step 4: Keep a safety buffer
Don’t forget about the ongoing costs. Insurance, taxes, and maintenance will come up year after year. Having a buffer set aside ensures these expenses don’t derail your plans.

By following these steps, you’ll know what you can afford, how much to save, and which financing path makes sense. That makes reaching your property investment goals in Germany far more realistic.
