But how many homes are there on the national market with moderate rents? Data from idealista/data reveals that eight out of every 10 homes for rent in the summer of 2025 have rents between 400 and 2,300 euros, covering most of the existing supply in large cities like Lisbon and Porto.

This new concept of moderate rent has generated considerable controversy within the real estate sector, which criticizes, above all, the upper limit for being out of touch with the reality of most Portuguese people and potentially even encouraging price increases. However, the government has argued that the moderate rent ceiling of 2,300 euros serves precisely to ensure the coverage of tax benefits nationwide, including areas experiencing greater housing price pressure, such as Lisbon and Porto.

According to idealista/news, during the third quarter of 2025, more than 43,000 houses were registered in the Portuguese rental market, distributed across 79 municipalities with representative samples (i.e., 50 or more properties). And the vast majority of these houses (81% of the total) are on the market with moderate rents between 400 and 2,300 euros. The largest supply is observed in Lisbon, Porto, Cascais, Vila Nova de Gaia, and Matosinhos.

It appears that practically all the municipalities analysed have more than half of the houses for rent within the moderate price range—and eligible for tax benefits for owners. This is the case in the capital (73% of the municipality's inventory), the municipality of Porto (91%), and Gaia (89%). Figueira da Foz stands out, as all 233 homes on the rental market are moderate-income.

The only exception is Cascais. In this municipality located in Greater Lisbon, the supply of homes in the premium rental market (53%) exceeds the supply of moderate-income properties (47%), as shown by the same idealista/data data. On the other hand, not a single home was found in this municipality priced below €400.
