Kaufnebenkosten: The Purchase Costs You Can't Finance

"Kaufnebenkosten — the additional purchase costs beyond the property price — are one of the biggest financial surprises for first-time buyers in Germany, especially expats accustomed to markets where closing costs are lower or rolled into the mortgage. In Germany, these costs total 10–15 % of the purchase price and must almost always be paid from your own savings, because banks do not consider them value-adding to the property. This guide breaks down each component, shows how costs vary by state, and explains how to budget for them.",

Why Banks Don't Finance Kaufnebenkosten

"German banks secure their loan against the property's Beleihungswert (lending value). Kaufnebenkosten — taxes, notary fees, and commissions — don't increase the property's value. If the bank had to foreclose, it could sell the property but would never recover the transfer tax or notary costs. Therefore, financing these costs would create an immediate gap between the loan amount and the security value. This is why banks insist you cover them from equity.",

Component 1: Grunderwerbsteuer (Property Transfer Tax)

"The Grunderwerbsteuer is the largest single cost component, ranging from 3.5 % to 6.5 % of the purchase price depending on the federal state. It's levied by the state government and is non-negotiable — there are no deductions, exemptions (except between spouses), or ways to reduce it.",

Transfer Tax Rates by Federal State (2025)

3.5 %: Bavaria (Bayern), Saxony (Sachsen)
5.0 %: Baden-Württemberg, Bremen, Lower Saxony (Niedersachsen), Rhineland-Palatinate (Rheinland-Pfalz), Saxony-Anhalt (Sachsen-Anhalt)
5.5 %: Hamburg, Mecklenburg-Vorpommern
6.0 %: Berlin, Hesse (Hessen)
6.5 %: Brandenburg, North Rhine-Westphalia (NRW), Saarland, Schleswig-Holstein, Thuringia (Thüringen)

"The difference is enormous in absolute terms: on a €400,000 property, the transfer tax ranges from €14,000 (Bavaria) to €26,000 (Brandenburg). This single line item can represent the entire difference between an affordable and unaffordable purchase.",

Component 2: Notar Fees

"In Germany, all property transactions must be conducted through a Notar (notary public). The Notar is a neutral legal officer who drafts the purchase contract, verifies identities, ensures both parties understand the terms, and handles the legal transfer of ownership. Notary fees are regulated by the Gerichts- und Notarkostengesetz (GNotKG) and are not negotiable — they're based on the purchase price.",

"Typical Notar costs amount to approximately 1.0–1.5 % of the purchase price. This covers: the purchase contract (Kaufvertrag), the land charge registration (Grundschuldbestellung) for the bank's mortgage, priority notice of conveyance (Auflassungsvormerkung), and various certifications and official copies.",

Component 3: Grundbuch (Land Registry) Fees

"The Grundbuch (land registry) charges fees for recording the change of ownership and registering the bank's Grundschuld (land charge). These fees are also regulated and typically total 0.3–0.5 % of the purchase price. Common entries include: ownership transfer, Grundschuld registration, Auflassungsvormerkung, and deletion of seller's existing charges.",

Component 4: Maklerprovision (Agent Commission)

"If a real-estate agent (Makler) was involved in the sale, the buyer pays a share of the commission. Since the December 2020 reform, the buyer's share cannot exceed the seller's share. In practice, this means the total commission (typically 5.95–7.14 % including VAT) is split equally, with the buyer paying 2.975–3.57 %.",

"Commission rates vary by region. In Berlin, the standard is 7.14 % total (3.57 % each). In Hamburg, it's 6.25 % total (3.125 % each). Some transactions — especially direct purchases from developers — involve no agent, eliminating this cost entirely. Always clarify the commission structure before signing a purchase offer.",

Total Kaufnebenkosten by State: Worked Examples

"Here's the total for a €400,000 property in different states, assuming the buyer pays a 3.57 % agent commission:",

Bavaria: 3.5 % tax + 1.5 % notary + 0.5 % Grundbuch + 3.57 % agent = 9.07 % = €36,280
Hamburg: 5.5 % + 1.5 % + 0.5 % + 3.125 % = 10.625 % = €42,500
Berlin: 6.0 % + 1.5 % + 0.5 % + 3.57 % = 11.57 % = €46,280
Brandenburg: 6.5 % + 1.5 % + 0.5 % + 3.57 % = 12.07 % = €48,280
Without agent (direct purchase in Bavaria): 3.5 % + 1.5 % + 0.5 % = 5.5 % = €22,000

"The spread between the cheapest and most expensive scenario is striking: buying agent-free in Bavaria costs €22,000 in Nebenkosten, while a brokered purchase in Brandenburg costs €48,280 — a difference of €26,280 for the same property value.",

Can Kaufnebenkosten Ever Be Financed?

"In rare cases of Vollfinanzierung (110 % financing), some banks will include Kaufnebenkosten in the loan. However, this requires an exceptional borrower profile — very high income, perfect SCHUFA, and a highly desirable property. The rate premium for financing Nebenkosten is steep, typically 0.7–1.0 % above standard rates. For most buyers, paying Nebenkosten from savings is both the norm and the financially sensible approach.",

How to Budget for Kaufnebenkosten

Identify your target state and look up the exact Grunderwerbsteuer rate.
Check whether an agent is involved and at what commission rate.
Add 2 % for notary and Grundbuch (a safe estimate).
Sum up all components to get your total Nebenkosten percentage.
Multiply by your target purchase price for the absolute cash amount needed.
Add this to your property equity target and renovation/emergency buffer to get your total savings goal.

Timing of Payments

"Kaufnebenkosten are not all due at once. The typical sequence is:",

Notary fee: Due within 2–4 weeks of the Notar appointment.
Grunderwerbsteuer: The tax office sends a notice (Grunderwerbsteuerbescheid) after the Notar files the contract. You typically have 4 weeks to pay. Ownership transfer is blocked until this is paid.
Agent commission: Usually due within 14 days of the purchase contract being signed.
Grundbuch fees: Invoiced after registration — often 2–3 months after closing.

"Ensure you have the full amount liquid and accessible in a German bank account before the Notar appointment. While you have a few weeks' grace on the tax payment, delays can hold up the entire transaction.",

Strategies to Reduce Kaufnebenkosten

Buy in a low-tax state: If you're flexible on location, Bavaria and Saxony save you up to 3 % compared to Brandenburg or NRW.
Buy directly from the owner: Eliminating the Makler saves 3–3.57 % of the purchase price. Online portals like eBay Kleinanzeigen, ImmoScout (filter for 'provisionsfrei'), or local newspaper listings can help.
Negotiate the movable inventory separately: Items like a fitted kitchen (Einbauküche) or furniture can be listed separately in the purchase contract and are not subject to Grunderwerbsteuer. This is legal as long as the valuation is reasonable (typically up to €10,000–€15,000).
Buy new from a developer: Some developers cover or share the agent commission to attract buyers.

Key Takeaways

"Budget 10–15 % of the purchase price for Kaufnebenkosten and plan to pay them from your own savings. The largest component is the state-specific transfer tax, followed by the agent commission and notary/registry fees. These costs are non-negotiable and non-financeable under normal circumstances. Factor them into your total savings target from day one — they are as important as the property equity itself.",
