The document basis is not sufficient yet.
Request the missing documents first. Without them, it is not possible to assess whether purchase price, escrow, handover or warranty are properly regulated.
A binding offer should not leave this gap open.

Estate agent commission often becomes concrete only when offer, reservation and financing already create pressure.
Buyers should clarify early which agency service was provided, whether a dual agency role exists and how the commission fits into total costs.
This article supplements the existing reservation and ancillary cost content without repeating it.
Quick check
Is this point clarified before signing?
Two questions show whether documents and contract wording fit together.
Already know you want to get in touch? Go straight to the enquiry form.
Are the decisive documents available?
Draft contract, evidence and economic consequences must be reviewed together.
All paths at a glance
Overview of all answers.
The basis is documented, but the contract must be read carefully.
If documents and draft contract match, the starting point is better. Still check maturity, assurance, retention, withdrawal right and handover consequences in detail.
The risk is not sufficiently protected in the contract yet.
If the draft remains general, it should be revised before signing. Depending on the situation, a condition, purchase price retention, seller assurance or clear handover mechanism may be appropriate.
Review agency service and commission basis
Review agency service and commission basis
Before payment, it should be clear which agreement and which concrete activity support the commission claim.
The existing article on the reservation agreement in a property purchase shows the separation from the pre-contract phase.
Commission and reservation payment should not be mixed. They have different legal bases and different risks.
Make dual agency transparent
Make dual agency transparent
Dual agency can occur in Austria. The decisive point is disclosure and whether buyers understand which information they receive and which interests are affected.
The central anchor remains purchase contract review.
Unclear communication often leads to later disputes about expectation, service and cost.
Calculate ancillary costs before commitment
Calculate ancillary costs before commitment
Commission is only one part of ancillary purchase costs. Taxes, fees, contract costs and financing costs must also be included before a binding step.
The incidental costs calculator gives first orientation. The documents checklist helps prepare.
If commission is calculated only after the offer, a financing gap may arise.
Think through cost consequences in the purchase structure
Think through cost consequences in the purchase structure
The purchase contract does not replace the brokerage agreement, but it can influence the overall economic structure.
Before signing, clarify which payments outside the purchase price have already been made and whether they are credited to costs.
This prevents later arguments about the purpose of a payment.
Review points
Which contract questions matter before payment
The overview shows which points should not remain open.
| Point | Evidence | Risk without review |
|---|---|---|
| Agent role Service and mandate documented | Commission is asserted unclearly | |
| Reservation Binding effect and costs separated | Payment is misunderstood | |
| Ancillary costs Total costs calculated early | Financing gap arises | |
| Contract Cost consequence recorded in writing | Dispute after signing |
The concrete contract solution depends on the property and available documents.
Careful: This point should not be reviewed only after signing. Known risks belong into the contract, escrow and handover structure beforehand.

Frequent questions

When does a commission claim arise? +
That depends on the brokerage agreement, the agent activity and conclusion of the transaction. Before payment, the causal service should be reviewed.
Is dual agency automatically problematic? +
Not automatically. The role must be transparent and buyers should know which interests and information stand on which side.
Should commission be included in the financing calculation? +
Yes. Commission, real estate transfer tax, registration fee and contract costs must be included in total costs before binding commitment.
