Why Rental Vacancy Rates in Lisbon Are at Record Lows—and What It Means for Renters and Buyers

Lisbon’s rental market is tighter than ever. The city’s latest data shows the vacancy rate for long-term rentals in the historic core has dipped below 0.7%—a level not seen for more than a decade. In hot neighbourhoods like Mouraria and Santos, apartments are being snapped up within hours, and some renters are offering to pay a year’s rent upfront just to edge out the competition.

Why the Shortage Has Hit Now

The pressure on Lisbon’s rental housing isn’t new, but conditions have worsened sharply this summer. A surge of digital nomads and remote workers, coupled with robust tourism and a still-active Golden Visa and D7 residency market, continues to squeeze residents. The city’s 2025 cap on short-term rentals—like Airbnbs—in the historic centre was supposed to provide relief, but local agents say units have not returned to the long-term pool as quickly as hoped. Instead, landlords are holding out for foreign tenants willing to pay a premium, or selling off stock to investors seeking capital appreciation in booming districts like Príncipe Real and Campo de Ourique.

"Finding anything under €1,500 a month in the Avenida da Liberdade corridor is nearly impossible," said an independent property manager in their office just off Rua das Portas de Santo Antão. The municipal housing portal, Habitar Lisboa, is reporting its lowest-ever inventory in parishes like Arroios and Estrela, where competition for T2 (two-bedroom) apartments is especially acute.

Crunching the Numbers: Supply Thin, Demand Relentless

A report released last week by Confidencial Imobiliário reveals the capital’s overall rental vacancy dropped to 0.9% in Q2 2026. For context, a healthy market typically hovers closer to 3%. At the same time, average asking rents have soared—up 7.2% year-on-year to €18.40 per square metre, putting a 60m² flat in Alcântara at around €1,100–€1,200 per month. Some areas are hotter than others: Baixa and Chiado listings for one-bedrooms are rare, with more than fifty applicants reportedly responding to each new posting on platforms like Idealista.pt.

For would-be buyers, the calculus isn’t much easier. Lisbon’s house prices are holding steady, with the INE (Statistics Portugal) median sale price at €4,250 per square metre in April 2026. Mortgage rates remain high, hovering between 5.1%-5.6%. Many young professionals find themselves priced out, unable to transition from renting to owning.

What’s Next—and Tips for Tenants

There’s little sign of immediate relief on the horizon. City officials are touting new developments along Avenida 24 de Julho and the Marvila riverfront, but most will not be ready for occupancy before 2028. In the meantime, renters are being urged to expand their search beyond the traditional centre: Laranjeiras and Lumiar, for instance, have slightly higher vacancy rates and more accessible pricing.

Experts from the consumer association DECO recommend preparing all paperwork—including proof of income, tax identification, and guarantor details—in advance to move quickly on listings. Affordable options, such as municipal housing lotteries, remain limited relative to demand. As Lisbon continues attracting a global rental audience, locals navigating the market can expect more competition—and fewer bargains—at least for the foreseeable future.
