Long-Term Rentals in Cascais: Lease or Furnished Stay?

What does a long-term rental in Cascais mean?

It can mean two different things, and they suit different people. The first is a standard residential lease, the kind a resident signs to live in a home as their main address. The second is a furnished stay of a month or more with a manager, with the home ready to use on day one.

Portugal Portfolio offers the second and not the first. We manage furnished holiday homes in Cascais and Lisbon for owners and rent them to guests. We do not broker residential leases, we do not sell property and we are not an estate agent. If you want a lease, you will need to find the home through another route and take advice on the contract.

How does a standard residential lease work in Portugal?

The Civil Code (Código Civil) lets a residential lease run for a fixed term or for an indefinite duration (article 1094, paragraph 1). If the parties are silent, the contract is treated as a fixed term of five years (article 1094, paragraph 3). The agreed term cannot be shorter than one year or longer than 30 years, and it is extended or cut to those limits automatically (article 1095, paragraph 2).

The one-year minimum does not apply to contracts for non-permanent housing or for special transitional purposes, such as professional, education and training or tourism reasons, stated in the contract (article 1095, paragraph 3). For tourism reasons, only one such contract can be made for each unit in a calendar year (paragraph 4). A standard lease is often unfurnished, though the articles quoted here do not say so. We do not cover deposits, guarantors or other conditions on this page. Ask a Portuguese lawyer or the relevant authority.

What does a furnished stay of one to six months cost in Cascais?

The median furnished stay of 28 nights or more cost €4,950 per 30 nights. This comes from 29 stays in 19 homes that Portugal Portfolio manages in the Cascais area, 12 months to 31 October 2026. All prices are for accommodation only, before cleaning fees and tourist tax.

The winter median was €4,000 per 30 nights, and the median winter stay lasted 42 nights. A studio or one-bedroom had a median of €2,000, so a longer stay in a small home in winter is where the numbers are lowest. Accommodation only, before cleaning fees and tourist tax.

Which one suits you, a lease or a furnished stay?

A lease suits someone who is already settled and plans to stay for a year or more. A furnished stay suits someone who needs a home for a shorter, defined period.

Is a furnished stay a good first step before a lease?

For many newcomers, yes. A standard lease commits you to at least one year, or five if the contract is silent (articles 1094 and 1095). A wrong choice of town, street or building is expensive to undo, and a furnished month or two shows you what a commute and a neighbourhood are like before you sign.

The CP Cascais line has stops at Cascais, Estoril, Carcavelos, Parede, Oeiras and Belém, and the timetable valid since 6 April 2026 shows about 40 minutes from Cascais to Cais do Sodré. Our relocating to Portugal guide covers what to have ready and how to plan the first months. Whether a stay suits your situation depends on your plans, so ask the team.

How is a furnished stay different from a short holiday let?

The length of the stay and the way it is documented. Decreto-Lei 128/2014, as republished by Decreto-Lei 76/2024, presumes local accommodation (article 4, paragraph 2) where a furnished and equipped property is offered to the public with services such as cleaning for periods under 30 days. A stay of a month or more falls outside that presumption. The team confirms the paperwork for your dates, and you should take legal or tax advice if you need certainty.

The mid-term rentals page and the monthly rentals guide explain the stays we offer, and the comparison of mid-term and short-term goes into more detail. You can also browse Cascais homes.

Where does the information in this guide come from?

The revenue, occupancy and price figures on this page are Portugal Portfolio's own data. Legal and tax rules were read at the official sources listed below on 10 November 2026. If a source changes, the source is right.

• Portugal Portfolio booking records 34 homes in the municipality of Cascais with guests across the 12 months from 1 November 2025 to 31 October 2026, 6,468 nights sold. Each night is counted once. Where the same stay appears twice, the lower price is used. No group has fewer than 5 homes.
• Codigo Civil, articles 1094 and 1095 (PGDL) Article 1094 allows fixed-term or indefinite residential leases and treats a silent contract as a five-year fixed term, article 1095 sets a term of at least one and at most 30 years, and paragraphs 3 and 4 exempt non-permanent housing or special transitional purposes (professional, education and training, tourism) from the minimum, with one tourism contract per unit per calendar year.
• Decreto-Lei 128/2014 as republished by Decreto-Lei 76/2024 (Diario da Republica) Article 4, paragraph 2(b) presumes local accommodation for a furnished and equipped property offered to the public with services such as cleaning for periods under 30 days, and paragraph 3 says the presumption can be rebutted under general law, for example with a registered lease.
• CP Cascais line timetable, valid since 6 April 2026 Stations from Cascais to Cais do Sodre, about 40 minutes from Cascais to Cais do Sodre on weekday trains, about 36 from Estoril, and weekday daytime departures every 20 minutes from Cascais.

What could not be confirmed. Not confirmed from an official source: deposit and guarantor rules for residential leases (the page does not state them), whether a standard lease is usually unfurnished (the Civil Code articles do not say so, and the page says only 'often'), and the contract type used for a given furnished stay.
