Buying a property, launching a rental investment, or selling an apartment: each real estate project requires legal, financial, and technical skills that most individuals do not master on a daily basis. Since January 2026, the extension of RE2020 to major renovations and the strengthening of anti-money laundering standards have added layers of administrative complexity. Understanding where the real bottlenecks are helps avoid months of delays or even financial losses.
Anti-money laundering standards 2026 and real estate projects: the blockages that no one anticipates
Have you noticed that a financing file takes longer than before? It’s not a coincidence. The requirements for identity verification and fund traceability have tightened in 2026 for real estate transactions. Notaries, banks, and intermediaries must now document the source of every contribution, including family donations or income from foreign investments.

For a novice investor, the consequence is direct: an incomplete file blocks the transaction for several weeks. A transfer received from a foreign account without supporting documentation, a poorly traced cash contribution, or a structure through a SCI with vague statutes is enough to trigger a request for additional justification.
Real estate support professionals have not all integrated these new constraints into their processes. Some firms continue to prepare files without anticipating the documents required by banking compliance units. The result: the compromise is signed, but the financing remains suspended. Using the services of BTB Immobilier allows for structuring the file in advance with the required documents, even before actively searching for the property.

Energy audit and extended RE2020: what professional support changes
Since January 2026, RE2020 no longer only concerns new constructions. Major renovations must now certify their energy performance through prior audits. In practical terms, if you buy an old property to renovate, the cost and feasibility of the work depend on a diagnosis that only a certified study office can carry out.
Professional support includes managing this energy audit before signing the compromise. Without this step, you risk discovering after the purchase that bringing the property into compliance costs much more than expected, or that certain works are technically impossible in the existing structure.
Why the audit before the compromise changes negotiation
Having the audit report before committing provides a concrete negotiation lever on the price. The seller can no longer hide an unfavorable energy performance diagnosis behind a promise of light work. The buyer negotiates based on verified figures, not estimates.
A professional in real estate project management coordinates this sequence: search mandate, pre-selection of properties, energy audit, then purchase offer. This timeline avoids back-and-forth that wastes time and credibility with the seller.
Reducing disputes: what field feedback shows
According to a FNAIM study published in January 2026, projects supported by FNAIM professionals in 2025 recorded a 25% reduction in disputes compared to unaccompanied transactions. This reduction is explained by better anticipation of hidden defects thanks to enhanced diagnostics.
The diagnosis is not limited to the energy performance diagnosis. It covers the condition of electrical installations, the presence of asbestos, natural and technological risks, and recently, the compliance of individual sewage systems. Every unchecked point before the sale is a potential source of litigation after signing.
The key steps of support that reduce risk
- Verification of the property’s urban planning compliance (permits, declared extensions, easements) before any purchase offer
- Coordination of mandatory and recommended diagnostics, with cross-analysis of results by a professional independent of the seller
- Review of the compromise by a legal advisor distinct from the drafting notary, to identify clauses unfavorable to the buyer
- Monitoring the release of funds with anticipation of the anti-money laundering documents required by the bank
This sequence seems logical. In practice, the majority of buyers who proceed alone skip at least one of these steps, often due to a lack of time or knowledge of regulatory obligations.
Rental investment strategy: where support really makes a difference
The purchase of a primary residence and rental investment do not require the same skills. For a rental project, profitability depends on a precise calculation that includes the purchase price, the cost of renovations, applicable taxes, and market rent. Getting just one of these parameters wrong is enough to turn a profitable investment into a financial pit.
A professional specialized in rental investment does not just find a property. They analyze the local market, compare yields by neighborhood, and identify applicable tax incentives. They also anticipate management constraints: tenant turnover, rent control, energy efficiency obligations.
Rental management and regulatory compliance
Professional rental management takes care of the legal obligations that evolve each year. Since 2025, properties rated G on the energy performance diagnosis can no longer be rented. Properties rated F will follow in 2028. A professional manager plans the compliance work before the deadline to avoid forced vacancy.
- Calculation of net yield after charges, taxes, and provisions for work
- Selection of tenants with solvency checks in accordance with legal requirements
- Regulatory monitoring on rent control and energy performance obligations
Delegating management to a professional costs on average a few percentage points of the rent. This cost is offset by the reduced risk of unpaid rent and the time saved on administrative procedures.
The real estate market of 2026 rewards preparation and penalizes improvisation. The new regulatory constraints, whether related to the extended RE2020 or the strengthened anti-money laundering standards, transform every step of a project into an administrative control point. Surrounding yourself with competent professionals remains the most reliable way to secure a purchase or investment without facing unpleasant surprises after signing.
