Preliminary contract for house purchase or right of withdrawal from house purchase?

As of 01/01/2020, to the best of my knowledge, most prefab house suppliers will again raise their prices, some (our favorite) by about 5-6%. Now my husband and I would like to buy a house before the price increase, but we depend on selling our current house (owner-occupied) before paying for the new house. We cannot predict whether the sale of our current house will take weeks or months.

How do you think we should proceed? In the worst case, we will have to accept paying 15,000 to 20,000 euros more for the new house in mid/end of January/February than now in December. What is your opinion or what would you do?

It is also unpleasant in this context that if we sign a contract this year, we probably will no longer find a specialist to review the construction specifications and contract for us.

Are there relatively "non-binding" types of contracts where we can still secure the 2019 house purchase price?

Don't let yourself be rushed into anything. Pressure is a poor advisor. The year is over anyway.

You add the 5% also to the property being sold.

It is also unpleasant in this context that we will probably not find a specialist this year anymore who can review the construction performance specification and the contract for us upon signing.

Oops, is it already Christmas?

According to my knowledge, companies increase their prices in March.
Until then, one could look for an expert.
All other considerations are too late now anyway.
The construction performance specifications should have long been evaluated in this step of consideration. Otherwise, there is no point in discussing anything at this point in time, i.e., shortly before signing.
If the evaluations, e.g., of the construction performance specifications, are not yet completed, there is no need to debate about signing either.

Never ever let yourself be put under pressure! Then proceed as . Insist on that when selling. Have you at least secured the financing? You probably also need bridging finance.

The sellers always pressure with supposed price increases because they want a signature. Don’t let yourself get stressed out! Everything step by step.

The more you signal that you really like this offer, the more the seller will steer towards closing the deal.
Haste makes waste.
Only buy when everything you need for your security is clarified (construction performance description, house sale/financing...)
Check the accuracy of the seller's statement (note from ). Let someone call the company with feigned interest.
