Real Estate 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 legal deadlines for withdrawal and pre-emption. Most sales that fall through don't stumble over price, but over 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 purchase offer

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 needed 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 withdrawal period, which runs from notification of the preliminary contract, which limits the practical significance of the commitment made at this stage.

Step 2: the preliminary contract

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

The loan condition precedent deserves particular attention. It must specify the amount borrowed, the term, and the maximum interest rate accepted. 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 unenforceable and the buyer forfeits the deposit despite not having obtained financing. The buyer must also submit applications matching the stipulated terms: an application for a higher amount or a different term can be held against them.

Other common conditions relate to zoning, the absence of undisclosed easements, and the clearance of pre-emption rights.

The ten-day withdrawal period benefits the non-professional buyer and runs from the day after notification of the preliminary contract. Its starting point depends on the validity of this notification — which is why electronically signing 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 an incompressible ten-day cooling-off period has elapsed. Acceptance before that is void. This period is added to the time needed to process the file, which depends on the bank and on how complete the supporting documents are.

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

• The annual percentage rate of charge includes administrative fees, the guarantee, and insurance, and is the only indicator that can be reliably compared across offers.
• Borrower's insurance can be taken out with a provider other than the lending bank, provided the coverage is equivalent. This is the item where the difference is greatest over the life of the loan.

The guarantee takes the form of a mortgage or a surety bond, whose costs and release procedures differ significantly.

Step 4: the notary's due diligence

While financing is being arranged, the notary carries out their investigations: chain of title over thirty years, mortgage status, zoning, 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 covered in our article on the notary's role.

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

Step 5: the notarial deed and afterwards

The deed is signed at the notary's office, the funds are released, and the keys handed over. The notary then registers the sale with the land registry, making it enforceable against third parties, and sends the title deed in the months that follow.

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

Usage scenarios

First-time purchase of a main residence. The sensible order is to have your borrowing capacity confirmed before making an offer. An accepted offer without pre-assessed financing creates timeline pressure that later shows up in the loan terms.

Rental 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 whether it can be rented out in future.

Frequently asked questions

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

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

How much time elapses between the sale agreement and the deed? Generally two to three months, dictated by loan processing, the cooling-off 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 becomes void, with the deposit refunded — provided the applications submitted matched the terms stipulated in the preliminary contract.

Is borrower's insurance required by the bank? No. It can be taken out with a different provider offering equivalent coverage, and this is the item where the cost difference is greatest over the loan's duration.

Can you buy property without going through a notary? No, not for real estate: the deed must be notarial and registered with the land registry office.

Key takeaways

Three timelines move forward in parallel, and failure almost always comes from their falling out of sync. Financing imposes its own incompressible deadlines, including a ten-day cooling-off period on the loan offer that no urgency can shorten. Legal due diligence depends on responses from third parties. And the legal deadlines — withdrawal, 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 afterward costs dearly. Borrowing capacity, the ownership structure, renovation cost estimates, and the precise drafting of conditions precedent all belong in the first category.
