Private bidding procedure when buying property: clarify terms and your own limit before bidding

A private bidding procedure requires clear terms of participation and your own purchase-price limit. Learn which declarations you should check before bidding and why neither the label of the procedure nor a later contract date alone answers the question of binding effect.

The invitation states a starting price and a deadline for bids. That sounds straightforward. Before you participate, however, two different questions must be answered: how does the selling side organise the competition, and what legal declaration are you making yourself? This article concerns private property offers in Austria, not a judicial auction.

Request the procedure before you state a price

Our editorial recommendation: ask for the full terms of participation and keep exactly that version. Clarify whether non-binding price indications are first being collected, whether a signed purchase offer is required, or whether multiple rounds are planned. The mere label “Bieterverfahren” does not answer these questions.

Also ask how the end of a round will be communicated, whether later bids will still be considered and whether a financial pre-check is required. Do not expect automatic information about competing persons or their documents. For your decision you need the process for yourself, not other people’s financing data. If the conditions are only to be disclosed after submitting a bid, you will be missing an essential basis for participation.

Distinguish a procedural confirmation from an acceptance of the contract

§ 861 ABGB links the conclusion of a contract to matching declarations of offer and valid acceptance. As long as only negotiations take place and the corresponding declarations are missing, no contract arises from that. [VERTRAG] What matters is therefore the concrete content, not merely the subject line of an email or a green status in an input mask.

If the wording is unclear, ask for clarification before sending: is this only an expression of interest, already a binding offer or something else? Which conditions are actually included? An acknowledgement of receipt initially confirms receipt; whether it also constitutes an acceptance does not follow from its friendly wording alone. Likewise, a message that you are currently leading does not replace an examination of the full state of declarations.

Make a personal limit from the whole undertaking

Set your limit before the first round. Separate the maximum purchase price from additional funds needed for transaction costs, financing, necessary works and your ongoing household. This article does not give blanket percentages for incidental costs: which items apply to you must be clarified for the specific property and transaction.

Note down, alongside the financial limit, any conditions without which you do not want to buy. These can be missing documents, an unresolved financing decision or clarification of an included installation. A higher bid with unresolved prerequisites is not a better decision for you simply because it advances you to the next round. Have required conditions properly included in your declaration; a private note beside the submitted form does not change its content.

Do not confuse the binding period with the bidding round

According to § 862 ABGB an offer must be accepted within the period fixed by the offeror; before the expiry of the acceptance period the offer cannot generally be withdrawn. [FRIST] The organisational deadline for submitting a bid and the legal acceptance period for your offer can have different functions. Check both, rather than merely noting the final upload date in your calendar.

Do not rely on always being free to decide until a later date at a contractual office. In case of doubt the binding effect should be clarified before submission. Possible rights of withdrawal must be examined separately. § 30a KSchG concerns, under certain conditions, consumer declarations on the day of the initial viewing to cover an urgent housing need. It is not a general free exit option from any later bid. [RUECKTRITT]

Example: The second round no longer fits your plan

In the hypothetical case a household can finance the initially offered price together with its separately calculated additional expenses. A second round requires a higher price, although financing for that additional amount is still unresolved. One’s own limit is not raised simply to justify the viewing expenses already incurred. First the status of the first offer is checked; only afterwards does the household decide whether another declaration is sensible at all.

Secure a clear status after each round

Keep your declaration, the conditions used, the proof of dispatch and all responses together. Note which status is open, expired, rejected or, from a professional point of view, classified as accepted. Resolve contradictions before you submit another binding declaration in parallel for a different property. This article does not decide any specific contractual case nor the effectiveness of particular conditions. Its aim is to bring your price decision and your legal declaration together in time.
