What are the Differences Between Market Rent, Asking Rent, and Achieved Rent? And When Should Each Metric Be Used?

In the real estate market, three key metrics allow a clearer understanding of how asset pricing is formed: market rent, asking rent, and achieved rent. Although often confused, these concepts reflect different stages in the dynamics between landlords, tenants, and investors.

Market rent is an exclusive SiiLA metric. It is not based solely on listings or recent contracts but results from an analysis that combines variables such as location, building standards, liquidity, and vacancy.

The idea is to arrive at a number that represents the “fair rent” for a given property. In 2025, for example, the estimate for prime office space in São Paulo’s CBDs reached R$ 142.64 per sqm, a record level.

Asking rent corresponds to the value a landlord advertises when placing an asset on the market. It is an initial expectation, which may or may not be confirmed during negotiations. Analyses based solely on this indicator tend to be limited, as they reflect only listed values without necessarily representing actual closing conditions.

Achieved rent, in turn, is the price effectively agreed upon in contracts, reflecting the outcome of negotiations. Although it is concrete data, it can lag behind, since agreements signed at a given moment do not necessarily reflect current market conditions.

In this context, market rent stands out as the most accurate and up-to-date reference, as it neutralizes both the inflated expectations of asking rents and the potential distortions of achieved rents. It works as a balancing point, aligning intent, reality, and the sector’s fundamentals.
