QuintoAndar, the largest housing platform in Latin America, is celebrating the efficiency of its initiative that monitors and acts on the diversion of real estate transactions initiated on the platform and concluded without the due compensation of the company and its partner brokers—a practice known in the market as “bypass”.
In two years, more than 207,000 purchase and sale interactions, such as visits, proposals, and transaction history, were studied and investigated, with approximately R$ 6.5 million recovered by the company during the period and divided among all parties involved in the operation.
The program utilizes an algorithm that monitors suspicious behavior in the property sales journey and crosses internal databases with public data, such as property registrations and ITBI (Property Transfer Tax). In recent months, the proptech has also expanded the technological resources used, leading to even faster and more precise information matching. Consequently, the platform currently has the capacity to investigate approximately 20,000 properties daily, a performance 120 times higher than before the implementation of these mechanisms.
The increased efficiency was also reflected in the monthly reimbursed amounts. In July, the company recovered more than R$ 1.2 million—double the amount recorded in April and three times more than in May of 2025. The projection is that, annually, recovered amounts will reach R$ 20 million.
“Our anti-bypass program has demonstrated a real impact on protecting the revenue of partner agents, strengthening trust among all parties involved. This is fundamental for the healthy evolution of the sector,” says Lucas Lima, COO of QuintoAndar. “We will continue to invest heavily in this front because the commitment to a safer and more transparent real estate market is the foundation for us to provide a high-level experience to the entire ecosystem,” he concludes.
As next steps, QuintoAndar plans to further expand its actions to combat bypass. In addition to scaling extrajudicial and judicial collections, the plans include expanding operations to the transactions of partner real estate agencies in the Marketplace. For 2026, the company is also working on the development of intelligent technologies that allow for preventive action, anticipating the identification of behaviors that indicate an intention to divert the negotiation.
Bypass in practice
Bypass occurs when the buyer and seller, after being brought together by real estate agencies and/or partner brokers, decide to negotiate directly and exclude these professionals from the transaction. In practice, even with all the mediation work already performed, the two parties close the deal on their own outside the platform, failing to pay the brokerage commission due to the intermediaries who connected them and made the deal possible.
Once bypass is identified, platform users who participated in the process are notified extrajudicially and may face legal action. The amounts recovered through these measures are divided among the intermediaries who participated in the transaction.
The practice of bypass, besides violating Brazilian legislation and the agreements signed between the parties involved in the negotiation, also exposes owners, tenants, and buyers to risks. By concluding the negotiation directly, without professional guidance, both parties are vulnerable to issues such as poorly drafted contracts, risk of data leakage, lack of legal certainty, default, and potential fraud. Additionally, the absence of document checks and guarantees offered by brokers and the real estate agency can result in financial losses and legal disputes.
In addition to using the program’s technology, QuintoAndar provides a reporting channel so that clients, partner brokers, and member real estate agencies of the QuintoAndar Marketplace can be part of this good practice.
