What is it about?
Most buyers finance their property purchase through a bank. And the bank doesn't grant the loan on demand: it assesses the buyer and – often surprisingly for sellers – above all, the property itself. A large part of the documents the buyer's bank wants to see must therefore come from the seller. Those who provide these property documents early and completely sell faster, as the buyer's financing does not get stalled.
In practice, this is precisely the most common reason for collapsed or delayed sales: The buyer is enthusiastic, but their bank doesn't receive the necessary documents in time or completely – and without a reliable property valuation, there is no loan approval. The bank never finances "enthusiasm", but rather the proven lending value (Beleihungswert).
One topic has gained significant importance: energy efficiency. Banks are increasingly including energy performance in their valuation and terms. Properties with a poor energy performance certificate become harder and more expensive to finance – which reduces the pool of potential buyers and, in practice, means such properties more often go only to buyers with substantial equity or cash buyers. A good energy performance certificate is therefore no longer just a piece of paper, but a selling point.
Definition and meaning
By "Bank documents for financing", we mean all the documents a lending institution requires to grant a property loan to the buyer. They fall into two groups: the buyer's personal creditworthiness documents (proof of income, proof of equity, self-disclosure, SCHUFA) and the property documents that demonstrate the value and mortgageability of the property.
For sellers, the property documents are particularly relevant, as they must provide these: an excerpt from the land register, cadastral map, calculation of living/usable area, floor plans, building description, photos, energy performance certificate, and – for condominium apartments – the declaration of division, latest minutes of the owners' association meeting, economic plan, and information on the maintenance reserve.
From this, the bank determines the lending value – a deliberately conservatively estimated, sustainably realisable value, which is generally below the purchase price. The lending value and the buyer's creditworthiness together determine whether and under what terms financing will be granted.
Why it matters
Without complete property documents, the buyer's bank cannot determine the lending value and cannot give a binding commitment. Missing documents are the classic reason why a notary appointment is postponed or completely falls through.
The energy performance has a dual impact: it affects the property's value and the bank's willingness to finance. Properties with poor energy ratings are harder to mortgage, which deters buyers with standard financing and slows down the sale.
Sellers who proactively and orderly provide the documents give the buyer a faster loan process – and gain a decisive advantage themselves: the sale less often gets stuck with the bank, and serious buyers less often pull out.
The key sections
You should know and check these components:
Property documents (provided by the seller)
Land register extract (Grundbuchauszug), cadastral map/site plan, living space calculation, floor plans, building description, property photographs and the energy performance certificate (Energieausweis). For houses, additionally information from the building file.
WEG documents for owner-occupied flats.
Declaration of division (Teilungserklärung), the latest minutes of the owners' meeting, current economic plan (Wirtschaftsplan) and the amount of the maintenance reserve fund. Banks pay close attention to a healthy reserve fund.
Creditworthiness documents (provided by the buyer)
Salary or income statements, proof of equity, self-disclosure form and SCHUFA. Not viewable by the seller, but a prerequisite for approval.
Energy performance certificate and energy performance indicators.
Increasingly part of the valuation: efficiency class, energy source and renovation status influence the value and conditions. A good certificate broadens the buyer pool.
Mortgage lending value assessment (Beleihungswertermittlung)
The bank's internal valuation. It determines the mortgage lending value (Beleihungswert), which is usually below the purchase price and limits the maximum loan amount.
Draft purchase agreement
The bank wants to see the notarised draft before giving final approval – it confirms the purchase price, property and conditions.
Example
Energy Class and Financing – a Comparison
Two similar flats in Berlin are for sale at the same price. The difference lies in the energy performance certificate – and that precisely determines how easily buyers obtain financing.
Flat A – Efficiency Class B
Renovated, heat pump
Broad buyer pool: Banks are happy to finance, sometimes with incentives for energy-efficient properties. The sale is quicker.
Flat B – Efficiency Class G
Unrenovated, old oil heating
Banks factor in renovation costs and risk, demand more equity or are more cautious with financing. The buyer pool shrinks.
Practical Consequence for B
Often only buyers with substantial equity or cash buyers
A poor energy performance certificate effectively shifts the sale towards cash buyers – often associated with price reductions.
Mortgage lending value
Usually below purchase price
The difference between the purchase price and the mortgage lending value must be covered by the buyer with equity – another reason why creditworthiness and property matter together.
Who signs? Can a power of attorney be enough?
Responsibility and signature
The property and WEG documents are provided by the seller (for flats via the property management); the personal creditworthiness documents are provided by the buyer to their bank. The bank or financing broker provides the requirements list and determines the mortgage lending value. We compile the seller's documents so that any buyer's bank can use them directly.
The property documents are not 'signed', but provided; their accuracy is the responsibility of the owner. The buyer signs the loan agreement with their bank. The bank itself records the internal mortgage lending value assessment. The seller does not sign anything here with the buyer's bank.
Power of attorney and its scope
Yes, for the procurement of the seller's and WEG documents. With a power of attorney, we request the land register (Grundbuch), declaration of division, minutes and economic plan from the land registry office (Grundbuchamt) and property management. The buyer's creditworthiness and loan documents are unaffected by this – they are exclusively between the buyer and their bank.
For the seller's side, a power of attorney for 'obtaining property and administrative documents from the land registry office (Grundbuchamt), building supervisory authority (Bauaufsicht) and property management' is sufficient. A power of attorney from the seller cannot and should not include the credit decision or the buyer's personal creditworthiness proofs – that would not be permissible under data protection law and practically.
Do it yourself: step by step
- 1
Compile a complete property documents folder early (land register, cadastral map, living space calculation, floor plans, photos, energy performance certificate).
- 2
For owner-occupied flats, request the declaration of division, the last three minutes of the owners' meeting, the economic plan and the reserve fund status from the management.
- 3
Keep a valid, preferably good, energy performance certificate ready and correctly advertise the mandatory key figures.
- 4
Demand a property-specific financing confirmation from the buyer before reserving.
- 5
Provide the notarised draft purchase agreement in good time, as the bank wants to see it before approval.
- 6
Realistically plan that the mortgage lending value can be below the purchase price and that the buyer covers the difference with equity.
Your easy way
Or we take care of it for you
- We compile a bank-ready property documents folder that any buyer's bank can use directly.
- With a power of attorney, we request the WEG documents (declaration of division, minutes, economic plan, reserve fund) from the management.
- We organise a valid energy performance certificate and classify how the efficiency class influences financeability.
- We check the buyer's financing confirmation for property relevance, amount and reservations.
- We coordinate the timetable between the buyer's bank, notary and handover, so that financing does not become a bottleneck.
Important caveats
- The bank finances the lending value, not the purchase price – the buyer must cover the difference with their equity.
- A poor energy performance certificate reduces the pool of buyers and, in practice, lowers the achievable price.
- Missing owners' association documents (minutes, financial plan, reserve fund) are a common reason for delayed approvals.
- A low or disputed maintenance reserve fund can complicate the financing of an apartment.
- A financing confirmation without specific property reference is of little value for the seller's security.
Common mistakes
- Only start collecting property documents after the buyer's commitment.
- Treating the energy performance certificate as an annoying formality instead of using it as a financing and sales argument.
- Forgetting owners' association minutes and reserve fund status, thereby slowing down the buyer's bank.
- Assuming the bank will finance the full purchase price without equity.
- Confusing a non-binding online calculator with a genuine financing confirmation.
Frequently asked questions
- Why does the buyer's bank want documents from me as the seller?
- Because the bank assesses not only the buyer but also the property as collateral. For the lending value, it needs the land register (Grundbuch), areas, floor plans, energy performance certificate, and for apartments, the owners' association documents – all of which are held by the seller.
- Does the energy performance certificate really affect financing?
- Yes, increasingly. Banks incorporate energy efficiency into valuations and terms. Properties with a poor rating are harder to finance, require more equity, and more frequently attract only cash buyers.
- What is the difference between the purchase price and the lending value?
- The purchase price is the agreed price. The lending value is the conservatively determined, sustainably achievable value estimated by the bank – usually lower. The bank finances a proportion of the lending value, not automatically the purchase price.
- Do I, as the seller, need to see the buyer's creditworthiness documents?
- No, and you should not request them for data protection reasons. A property-specific financing confirmation from the bank, proving fundamental financeability, is sufficient.
- How can I, as the seller, speed up the financing process?
- By keeping all property and owners' association documents complete and organised, presenting a valid energy performance certificate, and providing the draft purchase agreement early. Then the buyer's bank can assess without delays.
