Property Purchase: Complete Legal and Financial Process

A property purchase runs on three timelines that move forward in parallel and only sync up at the end: the financing timeline, the legal due-diligence timeline, and the statutory cooling-off and pre-emption timelines. Most sales that fall through don't founder on price, but on a mismatch between these three clocks — a loan obtained too late, a poorly drafted condition, a pre-emption right discovered along the way.

Step 1: the offer to purchase

The written offer commits the buyer as soon as it is accepted by the seller: it forms the sale in principle, since there is agreement on the property and the price. An accepted offer is therefore not a mere expression of interest.

Two precautions are essential in practice. First, state the essential conditions — particularly financing — in the offer itself, rather than waiting for the preliminary contract. Second, set a validity period: an offer with no deadline theoretically remains open indefinitely.

The non-professional buyer retains the benefit of the cooling-off period, which runs from notification of the preliminary contract, which limits the practical scope of the commitment made at this stage.

Step 2: the preliminary contract

Whether a unilateral promise to sell or a bilateral sale agreement, the preliminary contract sets out the price, the description of the property, the planned date for the notarial deed, and the conditions precedent.

The loan condition deserves particular attention. It must specify the amount borrowed, the term, and the maximum accepted interest rate. If drafted in vague terms, it produces one of two equally undesirable effects: either it is too easy to invoke, allowing the buyer to withdraw without a genuine refusal, or it is ineffective and the buyer loses their deposit despite not having obtained financing. The buyer must also submit applications that match the stipulated characteristics: an application for a higher amount or a different term can be used against them.

Other common conditions relate to planning regulations, the absence of undeclared easements, and the clearance of pre-emption rights.

The ten-day cooling-off period benefits the non-professional buyer and runs from the day after notification of the preliminary contract. Its starting point depends on the regularity of that notification — which is why an electronic signature on a sale agreement secures the timeline, by establishing the delivery date beyond dispute.

Step 3: financing

The banking timeline is the most constrained of the three, and it is the one that dictates the date of the deed.

The loan offer issued by the bank cannot be accepted until after a mandatory ten-day reflection period. Any earlier acceptance is void. This period is added to the file-processing time, which depends on the bank and on the completeness of the documents provided.

Two financial points to watch, independent of the advertised rate:

• The annual percentage rate of charge includes arrangement fees, the security, and the insurance, and is the only indicator that is comparable across offers.
• Borrower's insurance can be taken out with a provider other than the lending bank, provided the cover is equivalent. This is the item where the difference is most significant over the life of the loan.

The security takes the form of a mortgage or a guarantee, whose costs and release arrangements differ considerably.

Step 4: the notary's checks

While financing is being arranged, the notary carries out their searches: thirty-year chain of title, mortgage register status, planning regulations, clearance of pre-emption rights, and the seller's situation.

These checks depend on responses from third parties whose own timeframes must be respected, which explains why a file cannot be sped up beyond a certain point. The details of this due diligence are set out in our article on the notary's role.

The technical diagnostics file is provided at this stage, and its content determines how the property can be used — particularly the energy rating, which has become a condition for letting. Our article on mandatory property diagnostics sets out the documents required depending on the property.

Step 5: the notarial deed and after

The deed is signed at the notary's office, the funds are released, and the keys are handed over. The notary then registers the sale with the land registry, which makes the sale enforceable against third parties, and sends the title deed within the following months.

Three matters remain to be dealt with after signing: transferring the energy and insurance contracts, any declaration to the local tax authorities, and — for a rental investment — choosing the tax regime, whose effect on net yield is covered in our article on property taxation.

Usage scenarios

First purchase of a main residence. The sensible order is to have your borrowing capacity validated before making an offer. An accepted offer without pre-assessed financing creates time pressure that later costs you on the loan terms.

Buy-to-let purchase. The ownership structure and tax regime are decided before the preliminary contract, since they determine how the deed is drafted. Changing them after signing requires a new transaction.

Property requiring renovation. Get quotes before making the offer, and include the amount in the financing plan rather than treating it as a later expense. The property's energy rating also determines its future letting potential.

Frequently asked questions

Does an accepted offer to purchase create a binding commitment? Yes, in principle, since there is agreement on the property and the price. However, the non-professional buyer retains their cooling-off period from notification of the preliminary contract.

What is the cooling-off period? Ten days for the non-professional buyer, starting the day after notification of the preliminary contract. Its regularity determines the starting point.

How long is it between the preliminary contract and the deed? Generally two to three months, dictated by loan processing, the reflection period on the bank's loan offer, and responses from third parties consulted by the notary.

What happens if the loan is refused? The condition precedent applies and the sale lapses, with the deposit returned — provided the applications submitted matched the characteristics stipulated in the preliminary contract.

Is borrower's insurance imposed by the bank? No. It can be taken out with a different provider offering equivalent cover, and this is the item where the cost difference is most significant over the loan's term.

Can you buy without going through a notary? No, for a property: the deed must be notarial and registered with the land registry office.

Key takeaways

Three timelines move forward in parallel, and failure almost always stems from their falling out of sync. Financing imposes its own unavoidable deadlines, including a ten-day reflection period on the loan offer that no urgency can shorten. Legal checks depend on responses from third parties. And the statutory deadlines — cooling-off, pre-emption — run independently of the other two.

The practical consequence can be summed up in one sentence: what is decided before the preliminary contract costs little, and what is discovered afterwards costs dearly. Borrowing capacity, the ownership structure, costing the renovation works, and the precise drafting of conditions precedent all belong to the first category.
