Real Estate Purchase: Complete Legal and Financial Process

A real estate purchase plays out across three timelines that move forward in parallel and only sync up at the very end: financing, legal due diligence, and the legal deadlines for withdrawal and preemption rights. Most sales that fall through don't stumble over price, but over a mismatch between these three clocks — a loan approved too late, a poorly drafted condition, a preemption right discovered along the way.

Step 1: The Purchase Offer

The written offer binds the buyer as soon as the seller accepts it: it forms the sale in principle, since there is agreement on the property and the price. An accepted offer is therefore not a simple 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 withdrawal period, which runs from the 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 sales agreement, the preliminary contract sets the price, the description of the property, the planned date for the notarized deed, and the conditions precedent.

The financing 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 loan refusal, or it is ineffective, and the buyer loses their deposit despite not having obtained financing. The buyer must also submit loan applications that are consistent with the stated terms: an application for a higher amount or a different term can be used against them.

Other common conditions relate to zoning, the absence of an undisclosed easement, and the clearing of preemption rights.

The ten-day withdrawal period benefits the non-professional buyer and runs from the day after the notification of the preliminary contract. Its starting point depends on the validity of that notification — which is why an electronic signature on a preliminary contract 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. Acceptance before that period is void. This period is added to the file processing time, which depends on the bank and the completeness of the documents provided.

Two financial points to watch, independent of the displayed interest rate:

• The annual percentage rate includes the processing fees, the guarantee, and the insurance, and is the only indicator comparable across offers.
• Borrower's insurance can be purchased from 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 conducts their investigations: thirty-year chain of title, mortgage status, zoning, clearing of preemption rights, and the seller's situation.

This due diligence depends on responses from third parties whose deadlines must be respected, which is why a file cannot be sped up beyond a certain point. The details of this process are covered in our article on the notary's role.

The technical diagnostic 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 renting out a property. Our article on mandatory real estate diagnostics details the documents required depending on the property.

Step 5: The Notarized Deed and Beyond

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, making it enforceable against third parties, and sends the title deed a few months later.

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

Usage Scenarios

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

Rental investment purchase. The holding structure and tax regime must be decided before the preliminary contract, since they determine how the deed is drafted. Changing them after signing requires a whole 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 affects its future rentability.

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, however, retains their withdrawal period starting from the 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 passes 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 the responses from third parties consulted by the notary.

What happens if the loan is refused? The condition precedent takes effect and the sale becomes void, with the deposit refunded — provided the loan applications submitted matched the terms stated in the preliminary contract.

Is borrower's insurance imposed by the bank? No. It can be purchased from a different provider with equivalent coverage, and this is the item where the cost difference is greatest over the life of the loan.

Can you buy a property without going through a notary? No, for real estate: the deed must be notarized 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 unavoidable deadlines, including a ten-day reflection period on the loan offer that no urgency can shorten. Legal due diligence depends on responses from third parties. And the legal deadlines — withdrawal, preemption — 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 holding structure, renovation cost estimates, and the precise drafting of conditions precedent all belong in the first category.
