Buying a property involves several months of procedures, various interlocutors, and a legal framework that evolves each year. The difference between a well-managed project and a burdensome journey often comes down to three or four decisions made very early, well before the first visit. This article outlines the steps of a real estate purchase, emphasizing the points where mistakes can be most costly.
Real Estate Purchase Budget: What Happens Before the Search
Most guides start with “defining your criteria.” In practice, the budget dictates all the criteria, not the other way around. An apartment with a terrace in a sought-after neighborhood is of no interest if your borrowing capacity only covers half the price.
Before consulting any listings, have your borrowing capacity assessed by your bank or a broker. This calculation includes your net income, recurring expenses, personal contribution, and the intended repayment period. The debt-to-income ratio remains capped: beyond the regulatory threshold, the application is rejected, regardless of your profile.
Also consider additional costs. Notary fees, borrower insurance, and any renovation work significantly increase the final bill. Incorporate these costs from the first budget calculation, not after you have found the property.

EPC and Energy Audit: Obligations to Check Before Signing

You have spotted a house that ticks all your boxes. The price is right. Why check the energy performance diagnosis before even negotiating?
Because EPCs carried out between January 2018 and June 2021 will no longer be valid from January 1, 2025. If the seller presents an old diagnosis, they will need to provide a new one before the sale. This detail can delay the signing by several weeks.
Regulations have also expanded the scope of the energy audit. From January 1, 2025, homes rated E will be subject to the regulatory audit upon sale, in addition to those rated F and G already subject to this obligation. For a buyer, this audit provides an estimate of the necessary work to improve the property’s performance, along with a timeline and priority order.
Another point to watch: the method for calculating the EPC has been adjusted for small areas and homes heated by electricity. Some properties that previously displayed an unfavorable label may now receive a better rating without any physical changes. Always compare the date of the EPC with the current regulatory corrections to determine if the document reflects the property’s current reality.
Purchase Offer and Sale Agreement: Timelines That Protect the Buyer
Once the property is found, the purchase offer formalizes your intention. It can be verbal, but a written version offers better protection. Specify the proposed price, the validity period of the offer, and the financing conditions.
If the seller accepts, the signing of the sale agreement (or promise of sale) takes place in the following weeks, usually at the notary’s office. This document commits both parties, with a few exceptions.
- The ten-day withdrawal period starts the day after the delivery of the agreement. During this time, you can withdraw without reason and without penalty.
- The suspensive condition of obtaining a loan generally gives you several weeks to secure a financing offer. If the bank rejects the application, the sale is canceled, and your deposit is refunded.
- The mandatory diagnostics (EPC, asbestos, lead, termites depending on the area) must be attached to the agreement. Their absence can invalidate the withdrawal period.
A common pitfall: signing an agreement without verifying the compliance of the diagnostics. The notary checks the documents, but they do not visit the property. Review each diagnostic before signing, not after.
Financing the Mortgage: What the Bank Expects in Your Application

Your financing application dictates the next steps of the project. The bank assesses your creditworthiness, the quality of the property, and the coherence of the financial arrangement. A few elements make the difference between an application that is quickly accepted and one that drags on.
- Your personal contribution covers at least the notary fees. A higher contribution improves the proposed interest rate conditions.
- Professional stability carries weight: a permanent contract outside the trial period remains the easiest profile to finance, although other statuses are accepted.
- Bank statements from the last three months show your current management. Regular overdrafts weaken the application.
- Borrower insurance can be taken out with an external insurer, often at a more competitive rate than the bank’s group contract.
Once the loan offer is issued, you have a non-reducible reflection period before accepting it. Do not sign on the day of receipt, even if you are pressed by the sale’s timeline.
Signing the Deed of Sale at the Notary: Last-Minute Checks
Signing the authentic deed at the notary finalizes the sale. The notary verifies all legal documents, the discharge of any mortgages, and the proper transfer of funds.
Before this meeting, review the draft deed sent by the notary’s office. Compare it to the agreement: price, property description, mentioned easements, state of co-ownership charges if the property is in a collective building. Any discrepancies must be reported before signing, not on the same day in the notary’s office.
The transfer of ownership is effective upon signing the authentic deed. You leave with the keys, and the seller receives the sale price. The notary then takes care of the publication at the land registry.
A successful real estate purchase project relies less on luck than on the rigor of the initial steps. A realistic budget, verified diagnostics, and a solid loan application form the foundation. The rest, negotiation, neighborhood choice, decoration, comes naturally once the foundations are laid.
