Nothing is more frustrating than seeing a sale fall through shortly before the notary appointment because the buyer's bank ultimately refuses to cooperate. Meaningful proof of financing protects you from this – provided you know which documents are genuinely valuable and how to verify their authenticity. We show you which documents you should request from a specific prospective buyer, how to recognize a reliable commitment, and what you need to consider regarding data protection.
Why Proof of Financing Is So Important for Sellers
Many prospective buyers appear confident and convincingly assure you that they can easily afford the purchase price. But only when you enter into concrete negotiations with the preferred buyer does the crucial question count: Can this person actually raise the money? A failed sale costs you weeks, often months – and in the worst case, you then have to remarket the property as a “shelf warmer.”
Since April 1, 2023, a statutory ban on cash payments has also applied: Under Section 16a GwG, a domestic property may no longer be paid for with cash, crypto-assets, gold, platinum, or gemstones. The purchase price therefore almost always flows through a bank account. This puts the question of whether the buyer can raise the sum through equity, a loan, or a combination of both at the center of attention. A prospective buyer who insists on paying in cash is therefore a clear warning sign – legally, this method is no longer possible for the purchase price.
Which Documents You Should Request
Which document is useful depends on how the buyer intends to finance the purchase. In practice, most buyers combine equity and a bank loan.
The Bank’s Financing Confirmation
The most important document is the lender’s financing confirmation. It is not subject to any formal requirements, but should contain the key information:
- the buyer’s full name
- the loan amount the bank is prepared to provide
- the exact address and designation of your property
- the issuing bank, including contact details and contact person
- an issue date and a validity period (usually six months)
The confirmation does not yet contain a final interest rate – this is normal, because the The bank only sets the binding terms in the later loan agreement.
Proof of equity
If the buyer pays part of the purchase price from their own funds or even the entire purchase price without a loan, request proof of equity. Suitable evidence includes a current bank statement, a securities account statement, building society savings, or a brief bank confirmation of the available balance. For a buyer who wants to purchase entirely without financing, this proof of funds is even more important to the bank than any financing commitment.
Optional: Self-disclosure and SCHUFA credit report
For the bank, a SCHUFA inquiry is already a fixed part of the credit assessment. As the seller, you can also request a self-disclosure or a SCHUFA credit report from the buyer. This is particularly useful if the purchase is being made without bank financing and you would otherwise have no independent proof of the buyer’s ability to pay. Request such information only from buyers who are seriously being considered, not from every viewing guest.
Binding commitment or non-binding confirmation?
The most important distinction determines the value of the document: A non-binding financing confirmation merely signals that the bank is “generally prepared” to proceed, subject to a later credit and property assessment. It can be issued quickly, but offers you little security.
A binding financing commitment is issued by the bank only after it has fully assessed the buyer – this generally includes an identity card, proof of income and a SCHUFA report. Only this version reliably confirms to you that the prospective buyer is able to pay.
Look out for restrictive wording such as “subject to the final credit assessment” or “following determination of the lending value”. These are hallmarks of a non-binding confirmation – and are of little value for the security of your sale.
It is important to know: Even a binding commitment is not a one-hundred-percent guarantee. The bank may withdraw it if the buyer’s financial circumstances deteriorate significantly or the property’s lending value turns out to be substantially lower. Financing only becomes legally binding definitively with the loan agreement.
How to check that the proof is genuine
A financing confirmation can easily be copied or altered. Therefore, check it systematically:
- Reference to the property: Do the address and description of yourProperty specified exactly? A general confirmation without a specific reference to the property must always be regarded as non-binding.
- Buyer’s name: Is the prospective buyer named and identical to your negotiating partner?
- Date: Is the document current? A confirmation that is more than a few months old should be renewed.
- Issuing bank: Do the letterhead, contact details, and signature appear plausible? Unusual email addresses or missing contact persons are warning signs.
- Conditions: Does the bank link the disbursement to conditions unrelated to the matter? A proper commitment refers directly to the purchase of your property.
If doubts remain, ask the issuing bank or branch directly—with the buyer’s consent. A serious prospective buyer will have no problem with this. And another indication: If the bank’s review takes more than two weeks for no apparent reason, critical questions are warranted.
Data protection: How you must handle the documents
As soon as you receive bank statements, income, or creditworthiness data from a prospective buyer, you are processing highly sensitive personal data. The principle of data minimization under Art. 5 GDPR applies: Collect only what you really need.
- Request evidence only from a seriously considered buyer, not from every prospective buyer as a matter of course.
- Proof of ability to pay is sufficient—for the loan amount, individual transaction details on a bank statement are often unnecessary and may be redacted.
- Store the documents securely and return or delete them after the sale or a rejection.
This protects the buyer’s data and yourself from unnecessary risks.
FAQ on the buyer’s proof of financing
When may I request proof of financing?
The appropriate time is when a prospective buyer becomes a specific purchase candidate—at the latest, before the final price confirmation and the notary appointment. At this point, you have a legitimate interest in clarifying the ability to pay before taking the property off the market.
Is a financing confirmation legally binding?
Only to a limited extent. A non-binding confirmation does not bind the bank at all. A binding financing commitment follows a complete review, but may still be withdrawn if if the conditions change significantly. Only the loan agreement is finally binding.
How long is financing confirmation valid?
As a rule, about six months. If a buyer presents you with an older document, you should ask for an up-to-date confirmation – interest rates and creditworthiness may have changed in the meantime.
May a buyer pay the purchase price in cash?
No. Since April 1, 2023, § 16a GwG has completely prohibited cash payments when purchasing real estate; partial cash payments are also prohibited. The purchase price must be paid cashlessly, and the parties must provide proof of this to the notary. This proof requirement does not apply only when the transaction is handled through a notary escrow account or for consideration of up to 10,000 euros.
What should you do if an interested party does not want to provide proof?
Remain polite but consistent: Without reliable proof, you are taking an unnecessary risk. A solvent buyer will provide the confirmation without difficulty. If an interested party refuses to provide any information, that is a reason not to complete the sale for the time being.
Advantages and disadvantages of checking proof for sellers
- Advantage – Security: You screen out insolvent interested parties at an early stage and reduce the risk of a failed sale.
- Advantage – Negotiating position: A verified buyer gives you the confidence to take the property off the market with a clear conscience.
- Advantage – Time savings: You arrange the notary appointment and prepare the contract only with a realistic buyer.
- Disadvantage – Effort: Requesting and checking the documents takes time and requires care.
- Disadvantage – Data protection obligations: You are responsible for sensitive data and must observe the principle of data minimization.
- Disadvantage – no full guarantee: Even a binding commitment can fail in rare cases; a residual risk remains.
Conclusion: Checking protects against unpleasant surprises
Proof of financing is your most effective protection against a failed sale. Ask the preferred buyer for a financing commitment that is as binding as possible and specifically relates to the property or – in the case of cash buyers – a bank-issued proof of equity. Check the document for its reference to the property, date, and issuer, and contact the bank if in doubt. Anyone who follows these few steps will attend the notary appointment with a realistic buyer – and save themselves costly detours.
