A purchase offer in the context of a real estate purchase in Austria is often already a legally binding declaration. If the seller validly accepts a sufficiently specific offer within the applicable deadline, the purchase agreement may already come into existence. A genuine preliminary agreement, on the other hand, obliges the parties to conclude the main agreement at a later date. The heading on the form alone does not determine this.

As of September 2026. This article helps you assess the legal significance of a commitment before signing. The subsequent process involving escrow and land register registration is covered in our guide to real estate purchase agreements.

Purchase Offer and Preliminary Agreement: What Is the Difference?

Purchase offer: One party offers to purchase a specific property under clearly defined conditions. Valid acceptance may cause the agreement to arise immediately. The fact that a detailed purchase deed is to be prepared later does not automatically mean that no binding commitment exists until then.

Preliminary agreement: Both parties agree to conclude a more specifically defined main agreement at a particular point in time. Initially, the claim relates to the conclusion of that agreement. The Austrian Supreme Court expressly distinguishes this obligation from an immediate claim to transfer of ownership. Source: Austrian Supreme Court decision 8 Ob 148/09m.

Reservation: Check what is actually being promised. A document labelled “reservation” may contain binding obligations. Therefore, do not assume merely because of its name that it is a free, revocable reservation that can be cancelled at any time.

What matters most for your decision is this: Is the purchase intended to become binding upon acceptance, or do both parties merely undertake to conclude the agreement at a later date? Have any ambiguities clarified before signing.

What Must Be Defined in a Preliminary Agreement?

Section 936 of the Austrian General Civil Code requires, among other things, a specific date for the later conclusion of a binding preliminary agreement and the essential contractual terms. In a real estate purchase, these primarily include the specific property and the purchase price. The conclusion of the main agreement must be demanded no later than one year after the agreed date; this deadline is not a general withdrawal period. Source: Austrian Supreme Court decision 4 Ob 20/03z concerning Section 936 of the Austrian General Civil Code.

Do not use a preliminary agreement as a supposedly non-binding interim solution. If important issues remain unresolved, they and the consequences of leaving them unresolved must be expressly addressed. A general statement such as “we will sort out the rest later” does not provide reliable legal certainty.

What Does the Binding Period in a Purchase Offer Mean?

The binding period is the period during which the offer generally cannot be withdrawn at will. Record the date and, where applicable, the exact time. The acceptance period, payment deadline and planned handover date are separate matters.

Keep the complete signed purchase offer together with all attachments. Also have the acceptance declaration and its transmission documented. A message such as “the seller is generally in agreement” does not reliably establish whether an agreement was concluded or under which conditions. Regarding the binding effect of a purchase offer, the Austrian Chamber of Labour on withdrawal from a residential property purchase also points out that withdrawal options are limited.

Clarify Financing and Other Reservations in Advance

Any outstanding loan approval should be clarified before submitting the offer. If you need a financing condition, have it specified precisely which financing must be obtained by when and what happens if financing fails. A non-binding statement from a bank is not the same as secured financing.

For professionally drafted wording, at least the following questions should be answered:

• What financing amount is required and how much equity is available?
• What deadline applies to the bank’s decision?
• Which terms are decisive if the bank makes a different offer?
• What evidence must be provided in the event of a rejection, and to whom?
• Does the agreement only enter into force if the condition is fulfilled, or is a special right of withdrawal agreed?

The Austrian Chamber of Labour recommends a conditional purchase offer if the purchase still depends on financing. Source: Chamber of Labour Lower Austria on residential property purchases. These questions are a briefing for reviewing the agreement, not a universally suitable model clause.

Other unresolved issues may also be decisive: a building permit that still needs to be reviewed, a technical inspection of a defect, or the sale of the buyer’s existing property. Do not record only the unresolved issue; also specify the deadline, required evidence and legal consequence.

Can I Withdraw from a Purchase Offer?

There is no general right to change your mind after signing. First have it examined whether a valid binding commitment exists, whether an agreed condition has not been fulfilled, or whether a statutory or contractual right of withdrawal applies. A mutual cancellation must be agreed with the other party; merely wishing to withdraw is not sufficient.

A special consumer right is provided by Section 30a of the Austrian Consumer Protection Act. It applies to certain residential properties intended to meet the urgent housing needs of the consumer or a close relative, where the contractual declaration is made on the day of the first viewing. The period is one week and only begins once the consumer has received a duplicate of the declaration together with written information about the right of withdrawal. This special right expires no later than one month after the first viewing. Not every residential property purchase falls within this provision. Legal basis: Section 30a of the Austrian Consumer Protection Act.

If a dispute already exists, submit the purchase offer, acceptance, information provided, financing documents and the chronological sequence of events to a law firm or notary without delay. Whether, for example, a mistake, breach of contract or another legal basis exists must be assessed on a case-by-case basis. Deadlines should not be allowed to expire while further negotiations are taking place.

What Happens to the Commission if Financing Fails?

A rejected loan application does not automatically make an already valid purchase agreement non-binding. Nor does it automatically eliminate a commission claim. Under Section 7 of the Austrian Estate Agent Act, the entitlement to commission arises when the transaction brokered becomes legally effective. If the transaction ultimately does not proceed, it may depend, among other things, on whether the client is responsible for the reasons. Legal basis: Section 7 of the Austrian Estate Agent Act.

The purchase obligation, any possible claims by the seller and the estate agent’s commission should therefore be examined separately. An agreement cancelling the purchase with the seller does not automatically settle every claim by a third party. If an invoice is disputed, do not prematurely acknowledge liability and seek legal advice.

Checklist Before Signing

• Is it clear whether you are making a reservation, submitting a purchase offer or concluding a preliminary agreement?
• Are the property, purchase price, included inventory and deadlines clearly described?
• Do you have all documents that are essential for your decision?
• Is financing secured, or has a specifically reviewed condition been agreed?
• Are verbal promises documented in a traceable manner?
• Do you understand the consequences if a requirement is not fulfilled?
• Do you have a complete copy of all documents and sufficient time to review them?

Frequently Asked Questions

Am I Only Bound at the Notary Appointment?

Not necessarily. A validly accepted purchase offer may already create a binding commitment. The preparation of the agreement, payment of the purchase price and registration of ownership are separate matters.

Can I Add a Financing Condition Later?

You cannot unilaterally amend an agreement that has already become binding. Have any desired change expressly agreed with the other party and documented.

Is the Statement “You Can Withdraw at Any Time” Sufficient?

When purchasing real estate, do not rely on an unclear verbal statement. Have the scope, requirements, deadlines and costs of any promised right of withdrawal reviewed and recorded in writing.

Who Can Help with the Preparation?

For property documents and coordination of the purchase process, you can contact Simon Immobilien. The legal classification and drafting of a purchase offer or preliminary agreement should be individually reviewed by a law firm or notary.
