With the signature under a real estate purchase contract or a general contractor (GU) / total contractor (TU) contract, the buyer/contractor commits to paying several hundred thousand Swiss Francs. Therefore, it is worthwhile to carefully examine the opportunities and risks. Do not buy a "pig in a poke" so that the dream of homeownership does not turn into a nightmare.

An experienced expert will thoroughly review the contract and provide a comprehensive "Red-Flag" report, including tips for optimization.

What do I need to know about real estate contracts?

The real estate purchase contract is usually drafted by a notary appointed by the seller. The interests of the buyer are often inadequately considered. The contract is notarized and registered in the land register. Often, the mortgage deeds are also established simultaneously for financing arrangements. In the case of new buildings (general/total contractors), the construction contract is often integrated at the same time.

Actually always. Due to the freedom of design, there are many pitfalls. Individual clauses or missing regulations can have significant negative consequences.

Of course, the buyer can hardly ever achieve their optimum. But it is advantageous if the buyer is aware of the risks. In some cases, it is also possible to secure oneself elsewhere (e.g., insurance, guarantees). In addition, it is advisable to consider usage desires and risks on the buyer's side in the considerations (e.g., taxes, renovation costs, expansion/modification desires, marital property regime).

The purchase contract is signed before a notary and notarized by them. Since it can take several weeks until registration in the land register, this should be done in good time. Before registration, the bank will not provide the loan. The costs are usually borne by the buyer.

In most cases, warranty and liability are excluded to the extent legally permissible in the purchase contracts. Therefore, it is all the more important to uncover all defects at the handover. A precise description of the property can also help to assert warranty or damages claims afterwards.

In the case of construction contracts (individual/general/total contractors), it is essential to carefully examine how liability/warranty is regulated and whether any warranty claims are correctly assigned.

In principle, once a contract is signed, you cannot withdraw ("pacta sunt servanda").

Although there are certain legal remedies such as error, deception, improper contract performance, etc., which allow for withdrawal, the burden of proof (and thus the risk of costs) for the buyer is very high.
