Owning property in the Algarve, particularly in areas like Lagos, puts you in one of Portugal’s strongest rental markets. However, deciding whether to rent out your property for income is not simply a yes-or-no question. It depends on your goals, the type of property you own and how involved you want to be as a landlord.

This article outlines the financial, legal and practical considerations to help you make an informed decision.

The Algarve Rental Market

The Algarve remains one of Europe’s most popular destinations for both short-term tourism and long-term residents. Lagos benefits from:

• Strong year-round international demand
• A growing digital nomad and remote worker population
• Limited supply of quality rental properties
• Easy access to beaches, services, and transport

This combination makes rental income achievable (but not automatic).

Short-Term vs Long-Term Rentals in Lagos

Short-Term (Alojamento Local)

Pros

• Higher income potential during peak seasons
• Flexibility to use the property yourself
• Strong summer demand, especially near beaches and town centres

Cons

• Seasonal income fluctuations
• Higher management, cleaning, and maintenance costs
• Licensing and compliance requirements
• Dependence on tourism trends

Short-term rentals work best for well-located, fully furnished properties and owners willing to work with a professional management company.

Long-Term Rentals

Pros

• Stable, predictable monthly income
• Lower wear and tear compared to holiday lets
• Reduced management complexity
• Consistent demand from professionals, families, and expats

Cons

• Lower monthly returns compared to peak short-term rates
• Less flexibility for personal use
• Strong tenant protection laws

Long-term rentals are often better suited to owners seeking low-stress, reliable income rather than maximum yield.

Rental Income vs Costs

Before renting out your Algarve property, consider the full cost picture:

• IMI (municipal property tax)
• Rental income tax
• Condominium fees
• Maintenance and repairs
• Insurance
• Property management fees (if applicable)
• Utilities (often owner-paid in short-term rentals)

Net income, not gross rent, is what matters. A realistic financial projection is essential.

Legal and Tax Considerations in Portugal

Renting property in Portugal involves clear legal obligations:

• Short-term rentals require an Alojamento Local licence
• Rental income must be declared to the Portuguese tax authorities
• Non-residents may be subject to different tax rates
• Rental contracts must comply with Portuguese tenancy law

Professional advice from a local accountant or legal advisor is strongly recommended, especially for overseas owners.

Is Renting Always the Right Choice?

Renting out your property may not be the best option if:

• You rely heavily on personal use during peak seasons
• The property requires major renovation
• You prefer a hands-off investment without management involvement
• Market rents do not justify ongoing costs

In some cases, selling or holding the property for capital growth may be a better strategy.

How a Local Lagos Real Estate Agency Can Help

A local agency with on-the-ground experience can:

• Assess realistic rental income based on current market data
• Advise on short-term vs long-term suitability
• Connect you with trusted legal, tax, and management professionals
• Help you avoid costly compliance mistakes

Local knowledge matters, even more in a regulated and competitive market like the Algarve.

Summary

Renting out an Algarve property can be a solid income strategy, but success depends on planning, compliance and having realistic expectations.

The best results will come from understanding the market, the numbers and your own long-term goals.

If you own property in Lagos or the surrounding Algarve area, a professional assessment can help you decide whether renting is right for you and which rental model makes the most sense.
