What you can generate for Cascais
The Cascais market has a very active layer of international demand: Estoril, central Cascais and Birre have established pockets of expatriates. The supply of quality properties is limited, which sustains prices 20-30% above neighbouring municipalities. The Portuguese digital nomad visa has been a driver of new demand since 2022.

In Cascais, registration of the lease agreement follows the national 30-day regime through the Portal das Finanças. For contracts with foreign tenants (frequent in Cascais), the process is identical: the tenant's Portuguese NIF is mandatory for registration. If the tenant does not have a NIF, they must obtain one at the Cascais Tax Office before the contract is entered into.
Stamp duty
For a median rent of €1,433/month in Cascais, the Stamp Duty is €143.30 per contract. For houses with rents of €2,800/month (median), the Stamp Duty rises to €280. Landlords with multiple properties in Cascais should factor this cost into their profitability analysis, especially in luxury property portfolios with frequent turnover.
Landlord and tenant obligations
In Cascais, for premium properties, the landlord is obliged to keep all equipment in perfect condition (air conditioning, jacuzzi, security system, swimming pool if included). It is common to include a swimming pool and garden maintenance contract separate from the lease. For gated condominium properties, the condominium rules must be attached to the lease agreement as a binding document.
Frequently asked questions
Can I make a lease agreement in English in Cascais for a foreign tenant?
Legally, the contract may be bilingual (Portuguese + English), but the Portuguese version prevails in the event of a judicial dispute. For foreign tenants in Cascais, it is good practice to provide a bilingual contract with an official or sworn translation. Registration with the Tax Authority (AT) is always done in Portuguese with the details of the property and the parties. A bilingual contract has no additional legal cost but gives the foreign tenant more comfort.
In Cascais, is a bank guarantee mandatory for lease agreements?
It is not legally mandatory, but it is very common in the premium segment in Cascais. A bank guarantee (comfort letter issued by a bank) is an alternative to a security deposit by cheque; it costs 1-3% of the guaranteed amount per year but gives the landlord greater protection. For rents above €2,000/month, a bank guarantee or rent insurance are alternatives to the security deposit, which is limited by law to 2 months.
Can a lease agreement in Cascais include a swimming pool maintenance clause?
Yes. The lease agreement may include clauses on the maintenance of specific equipment, including the swimming pool, garden and HVAC systems. It is common in Cascais for the lease agreement of a house to establish that routine swimming pool maintenance (chemicals, weekly cleaning) is the tenant's responsibility, while equipment repairs (pump, filter) are the landlord's responsibility.
