A French couple I have been showing apartments in Lagos asked me this over coffee last week: “If we buy now and rent it on Airbnb until we retire, can the rental income pay the place off?” They are in their early fifties, want a two-bed near the water they can eventually retire into, and love the idea of the property earning its keep in the meantime.
It is one of the most common questions I get from second-home buyers. The honest answer is: partly, if you buy the right property and run it properly. But “paid off by Airbnb” is a stretch in 2026. Here is exactly what I told them.
Can Airbnb income actually pay off an Algarve apartment?
No, not on its own, and not at today’s prices. A well-located two-bed in Lagos or Meia Praia can realistically cover its running costs and a good chunk of a mortgage, but the era of short-let income clearing the whole purchase price is behind us.
Prices have run hard. Lagos now sits around 3,800 euros per square metre, with prime Praia da Luz pockets closer to 6,800. At the same time the rules around short-let have tightened. The gap between the dream and the spreadsheet is where I spend most of these conversations.
The 2026 short-let rules you actually need to know
Three things have changed the picture, and all three matter before you assume a single euro of income.
- Platforms now police licences. Since 20 May 2026, an EU regulation requires Airbnb, Booking.com and Vrbo to verify your Alojamento Local (AL) licence number and automatically delist any property that is not registered. No valid AL, no listing, no income.
- AL registration is property-specific. Whether you can even get an AL licence depends on the exact building and the municipality, and some zones restrict new registrations. So the first question is never “what will it earn,” it is whether this specific apartment can be registered for Alojamento Local at all. I check that per property, not per town.
- The 7.5% IMT still applies to non-residents. On a 500,000 euro purchase that is 37,500 euros in transfer tax alone, before notary, legal fees and furnishing. It reshapes the payback maths from day one, as I covered in my piece on Portugal’s 7.5% IMT for non-resident buyers.
I have talked buyers out of “perfect Airbnb flats” that could never legally be short-let. The yield only exists if the licence exists.
What the numbers really look like
I ran their exact profile through my own Algarve short-term rental simulator: a two-bed apartment in the Western Algarve, Lagos to Sagres, a 500,000 euro purchase, average occupancy of around 50% across the year, on professional management. Here is what it projected:
- Gross rental revenue: about 25,960 euros a year, built on nightly rates near 212 euros in peak July and August, 127 in the shoulder months, and 85 in winter.
- Running costs: about 8,190 euros, covering the 20% management fee, cleaning and platform fees.
- Net profit after the Portuguese simplified-regime tax: about 15,500 euros.
- Return on the purchase price: 3.1%.
That is a real, useful number. It covers your holding costs and a solid chunk of a mortgage, but it is not paying off a 500,000 euro flat on its own. And it swings hard on two levers: location and occupancy. Push occupancy up toward superhost level and the return climbs; drop to a new-listing 30% and it falls fast. That is exactly why I built the tool as a slider, not a single headline figure.
One market signal keeps me from modelling off best-case: national asking rents have now fallen for five straight months even as sale prices hit fresh records. Model off today’s reality, not off 2023’s peak.

Short-let, long-let, or keep it free for yourselves?
For a couple planning to retire into the place, the real decision is not just about income. It is about how much of the year you want the flat available for your own use. Here is how the three options compare.
| Short-let (AL / Airbnb) | Long-term let (12-month) | Keep it for your own use | |
|---|---|---|---|
| Income potential | Highest gross (~26k), ~3.1% net at average occupancy | Steadier, ~2.5 to 3.5% net, less volatile | None |
| Rules & effort | AL licence required, platform checks, high management | Standard lease, low effort, tenant protections | No letting rules to manage |
| Available for you? | Yes, block out your own dates | No, tied up for the tenant’s term | Fully, whenever you want |
| Best for | Owners wanting income plus summer access | Owners wanting hands-off, stable return | Buyers whose priority is the retirement home itself |
For buyers who genuinely want the property for retirement, short-let usually wins on flexibility: you earn in the peak weeks and still keep the place for your own spring and autumn stays.
What I told the French couple
Buy the apartment you would be happy to own even if it never earned a cent. Then treat short-let income as a way to offset the cost of holding it, not as a business plan that clears the mortgage.
The tailwinds are genuinely in their favour. France is now one of the top nationalities searching for Algarve property, and direct access keeps improving: Faro added more than 600,000 airline seats for summer 2026, which feeds both resale demand and holiday-let occupancy near the Lagos beaches. If the property is right and the licence is clean, the income is real. It just is not magic.
Frequently Asked Questions
Can Airbnb rental income pay off a retirement apartment in the Algarve?
Not on its own, not at 2026 prices. My Algarve rental simulator projects about 3.1% net, roughly 15,500 euros a year on a 500,000 euro two-bed at average occupancy, which covers running costs and part of a mortgage rather than the purchase price. Buy a place you would want to own regardless, and treat the rental income as a cost-offset.
Do I need an AL licence to rent my Algarve property on Airbnb in 2026?
Yes. Since 20 May 2026 an EU regulation forces Airbnb, Booking.com and Vrbo to verify your Alojamento Local licence number and delist unlicensed properties. Whether a given apartment can be licensed depends on the building and the municipality, so I always confirm AL feasibility on the specific property before we talk yield.
How much can a two-bed near Lagos earn on short-term rental?
My rental simulator projects about 26,000 euros gross and 15,500 euros net after tax at average, roughly 50%, occupancy, with peak nightly rates near 212 euros in July and August. Income is heavily concentrated in June to September. Run your own price and occupancy through the simulator to see your realistic range.
Is it better to short-let or long-let an Algarve apartment?
Short-let earns more gross and keeps the property available for your own dates, but it needs an AL licence and active management. Long-let is lower-effort and steadier at around 2.5 to 3.5% net, but ties the flat up for the tenant’s term. For buyers who want to retire into the place, short-let usually wins on flexibility.
Do non-residents pay extra tax buying a rental property in Portugal?
Non-resident buyers currently pay a flat 7.5% IMT transfer tax, which is 37,500 euros on a 500,000 euro purchase, before notary and legal costs. Factor it into your payback calculation from the outset.
